Information of Special Importance to Testing Laboratories

13th September 2017

Information for testing laboratories, calibration laboratories and other interested parties  

The Accreditation Body of Serbia (АТS) granted its first accreditations in 2000 to testing laboratories according to the then valid reference document for accreditation of laboratories, SRPS ISO/IEC Guide 25. Later in 2001 ATS started accrediting laboratories against SRPS ISO/IEC 17025 and has so far accredited over 400 laboratories.  

For 11 years reference document for accreditation of laboratories has been SRPS ISO/IEC 17025, whose last revision in the Institute for Standardization of Serbia was published in 2006.  Vast experience has been attained in application and assessment of observance of requirements of the said standard both in accredited laboratories and in ATS.   

Due to the changes in the environment where laboratories do business, International Organization for Standardization started activities on revision of ISO/IEC 17025:2005 in 2015 and currently voting on definitive text of the draft of the said international standard is in progress at it is carried out simultaneously in ISO and CEN. The voting will be carried out from 14th August 2017 to 9th October 2017. Publishing the standard globally is planned for November/December 2017. There are significant changes of the structure and content of the standard in comparison to the currently valid version of the standard.

Committee for standards and related documents КS CАSCO, Conformity assessment and quality management of ISS, participants of which are ATS representatives, has already started translating the standard FDIS ISO/IEC 17025, in order to provide the beneficiaries with the translation of the standard the immediately upon publishing on the international level. 

More detailed information on the condition of revision of the standard ISO/IEC 17025 can be found on the webpage of ISS http://www.iss.rs/rs/news/news_279.html.

ATS invites all accredited laboratories to monitor the state of revision of ISO / IEC 17025 standard and, in accordance with their needs, begin preparations for the harmonization of their work with the requirements of the new edition of the standard.

ATS will, immediately after adoption of appropriate resolution for transition to accreditation of laboratories according to new edition of ISO/IEC 17025 by the International Laboratory Accreditation Cooperation (ILAC), publish new information to all accredited laboratories on transition period and mode of transition to accreditation by ATS according to the future version of ISO/IEC 17025.

Information for CABs about change of rules in ATS

In February 2017, the Accreditation body of Serbia (ATS) made amendments in two documents: Rules for the Use of the Accreditation Symbol, Reference to Accreditation and ATS Status as a Signatory to the ЕА MLA, ILAC MRA and IAF MLA ATS-PA04 (technical correction published on ATS website on 19th April 2017) and Cross-frontier Accreditation Rules ATS-PA05 in order to conform them with the following changes in international documents:

- ATS-PA04, Rules for the Use of the Accreditation Symbol, Reference to Accreditation and ATS Status as a Signatory to the ЕА MLA, ILAC MRA are completely in compliance with the requirements of ILAC-R7:05/2015, Rules for the Use of the ILAC MRA Mark, IAF ML 2:2016, General principles on the use of the IAF MLA mark and EA-1/19 A:2015, Rules for Use of the EA Logo, as well as IAF resolutions (IAF Resolution 2015-14, Agenda Item 10 и IAF Resolution 2016-17, Agenda Item 9).

One of the significant changes refers to application of the decision by IAF GA (IAF Resolution 2015-14, Agenda Item 10 и IAF Resolution 2016-17, Agenda Item 9) which obligated CABs certifying management systems to use accreditation symbol on conformity assessment certificates for fields they are accredited for, in accordance with the granted Scope of accreditation.

It shall be deemed that the document for management systems certificates were issued by the process of accreditation if they have an accreditation symbol and/or refer to accreditation in the text and/or combined mark (if applicable).

Certification bodies that certify the management systems:

(1) must coordinate (conform) that the certification documents contain a symbol of accreditation or refer to accreditation at the time of making the decision about the recertification at the latest until the 6th November 2019

(2) during the process of making the decision on initial accreditation, i.e. the extension of the scope of accreditation for the new standard, starting 6th November 2019, certification bodies, which certificate the management systems must re-issue, previously issued non-accredited documents of certification in a period of one year until the date of making the final decision about accreditation.

Note: If there is an exception from the previous paragraph, the certification body’s Client, which certifies the management systems must justify this exception to both the certification body as well as to the accreditation body, and if they reach agreement between both parties, the certification in question will be considered to be accredited.

Point 2.2 of the document EA Rules for Use of the EA Logo EA-1/19 A:2015 stipulates that conformity assessment bodies accredited by EA members are not allowed to use EA logo. If you use EA logo on your website, it is vital that the logo be removed if you published it and the proof/information about it be sent to ATS to following email: office@ats.rs

Likewise, should you be interested in promoting international status of ATS as a signatory to the ЕА MLA/MRA and full member of international accreditation organisations (EA, ILAC, IAF), you can do so by putting the link to e.g. ATS logo which will direct to the ATS internet page containing the text about ATS status and international recognition (http://www.ats.rs/en/pages/international-organisations-and-agreements) – About us/International organizations and agreements and pursuant to point 3.2.1 of the Rules for the Use of ATS Logo ATS-PA07 which defines that “ATS logo may, upon request, be approved for use for other purposes, in adverts, articles, publications, on fairs, exhibitions, conferences/seminars and websites of other organizations.”

АТS-PА05, Cross-frontier Accreditation Rules  which defines ATS policy applied when accrediting conformity assessment bodies with the head office outside the Republic of Serbia or CABs established in the Republic of Serbia having sites and/or key activities in another country, and the policy related to cooperation with other accreditation bodies in case of cross-frontier accreditation; these Rules are fully in compliance with the requirements of EA- 2/13 М:2012, ILAC-G21:09/2012 and Regulation (EC) No. 765/2008 and they are additionally updated with the explanations of definitions concerning cross-frontier accreditation laid out in the document EA- 2/13 S1.

Information as regards accreditation of conformity assessment bodies for the purpose of designation to perform the conformity assessment activities referred to in the Regulation on Noise Emission by Equipment for Use Outdoors (“Official Gazette of the Republic of Serbia”, No. 1/13)

Application of the Regulation on Noise Emission by Equipment for Use Outdoors (“Official Gazette of the Republic of Serbia”, No. 1/13) (hereinafter referred to as: Regulation) started on 1st July 2015 and a notice thereof was posted on www.tehnis.privreda.gov.rs.

The notice stated that conformity assessment bodies accredited to perform testing of noise in keeping with SRPS EN ISO 3744:2008 can, prior to being designated to perform the conformity assessment activities referred to in Article 11 of the Regulation, issue certificates of conformity to local producers or, when applicable, to representatives of foreign producers as stipulated in Annexes 6, 7 or 8 of the Regulation and under conditions presented in the notice.

The Accreditation Body of Serbia hereby informs all interested conformity assessment bodies (CABs) that it will, as of 1st October 2015, receive CABs’ applications for accreditation that will allow them to perform conformity assessment activities in keeping with Article 11 of the Regulation (Annexes 6, 7 or 8 of the Regulation).

CABs can be granted accreditation for the said conformity assessment activities as per SRPS ISO/IEC 17020, SRPS ISO/IEC 17065 or SRPS ISO/IEC 17021 depending on the type of conformity assessment activities that need to be performed as per the said Annexes of the Regulation.

Accreditations can be granted in the course of initial assessments, reassessments or assessments performed to extend the scope of accreditation that had already been granted, whereas the awarded accreditation documents will serve as a proof of competence to perform conformity assessment in case of CAB designation as per the Regulation.

Moreover, it was determined, as defined in the EA policy stipulated in the document entitled EA-2/17 INF: 2014 that tackles CAB accreditation for the purpose of notification and as agreed with the Ministry of Economy (MoE document No. 110-00-165/2015-07 dated 22.07.2015), that accreditation documents (in addition to the aforementioned ones) that are in keeping with SRPS ISO/IЕС 17025 will be accepted (for the purpose of notification) as a proof of CAB competence and know-how to perform the conformity assessment activities referred to in Annexes 6 and 7 of the Regulation in case of testing laboratories performing testing of noise as per SRPS ISO 3744 if, during the accreditation procedure, additional assessments were performed to determine fulfilment of the requirements laid down in Annex 9 of the Regulation.

Hence ATS allows testing laboratories accredited as per SRPS ISO 3744 to perform noise emission testing to submit, as of 1st October 2015 (or even earlier if their regular surveillance assessments are planned to be carried out before 1st October 2015), applications to extend the scope of accreditation for the purpose of designation to perform conformity assessment as per Article 11 of the Regulation in case of the conformity assessment activities referred to in Annexes 6 and 7 of the Regulation. Assessments will be performed during regular surveillance assessments after the applications have been submitted or as a separate procedure after the applications to extend the scope of accreditation for the purpose of designation have been received. Laboratory assessment will include an assessment of their technical competence or assessment of their know-how and procedures used to make decisions on the basis of audits and evaluations prescribed in the Regulation and obtained noise testing results, whereas these decisions will need to confirm whether the Regulation requirements have been fulfilled or not. With this end in view laboratories should, in addition to all SRPS ISO/IЕС 17025 requirements, also fulfil the requirements referred to in clauses 4.1, 7.5 and 7.6 of SRPS ISO/IEC 17065 and this will be assessed during additional assessments on the basis of applications for the extension of the scope of accreditation for the purpose of designation. Accredited testing laboratories, the scope of which will be extended during the said procedure, will be issued the new extended Scope of Accreditation that will, in addition to regular information and data, contain clear information that a laboratory for conformity assessment in keeping with the Regulation was additionally assessed as per the relevant SRPS ISO/IEC 17065 requirements.

Application for the extension of the scope of accreditation for testing laboratories for the purpose of designation is posted under D.1.1A ANNEX TO THE APPLICATION FOR ACCREDITATION (for testing laboratories – SRPS ISO/IEC 17025) - ONLY FOR THE EXTENSION TO THE SCOPE OF ACCREDITATION FOR THE PURPOSE OF DESIGNATION. Completed and signed application forms with requested annexes have to be sent to the ATS’s address.

Information for testing laboratories performing periodic measurements of stationary source emissions

Pursuant to the decision of the EA General Assembly (EA GA) requiring that accreditation bodies signatories to the EA MLA should use, in the course of accreditation of testing laboratories performing periodic measurements of stationary source emissions, CEN/TS 15675 Air Quality - Measurement of stationary source emissions in addition to ISO/IEC 17025.

With that end in view the Accreditation Body of Serbia (ATS) published in February 2012 (version 1 dated 18.07.2014 being the valid one) the document entitled ATS-UP20, Guidelines for the Application of SRPS CEN/TS 15675 When Granting Accreditation to Testing Laboratories.

Application of SRPS CEN/TS 15675 in case of laboratories performing periodic measurements of stationary source emissions is prescribed by the Serbian legislation. Article 7 of the Regulation on the Conditions for Issuance of a License to Perform Measurement of Air Quality and License to Perform Measurements of Stationary Source Emissions (“Official Gazette of the RS“, No. 01/12) prescribes that a license to perform measurements of stationary source emissions shall be issued even if conditions as regards technical competence are fulfilled as per the requirements of SRPS ISO/IEC 17025 and SRPS CEN/TS 15675. Hence the respective ministry (Ministry of Agriculture and Environmental Protection) informed, by means of letter number 353-01-1012/2014-19 dated 11.09.2014, authorised bodies in this field about “a plan requiring that the assessment of legal entities currently authorised to perform measurements of stationary source emissions as per SRPS CEN/TS 15675 shall be finalised by the end of 2015, and that those legal entities that fail to fulfil the SRPS CEN/TS 15675 requirements after the expiry of the said period shall no longer be authorised by the Ministry to perform measurements of stationary source emissions”.

Having in mind the aforementioned, ATS will carry out the following:

• All testing laboratories accredited as per SRPS ISO/IEC 17025 that have waste gas option specified in their scopes of accreditation or that perform periodic measurements of stationary source emissions shall be assessed by the end of 2015 so that it could be determined whether they also fulfil the requirements of SRPS CEN/TS 15675.

• From 01.01.2015 ATS shall perform all assessments of testing laboratories performing periodic measurements of stationary source emissions by applying both SRPS ISO/IEC 17025 and SRPS CEN/TS 15675.

• The only exception shall pertain to testing laboratories that are being reaccredited and the accreditation certificate of which is valid until 31.03.2015, whereas they shall be assessed by the end of 2015 so that it could be determined whether they also fulfil the requirements of SRPS CEN/TS 15675.

• On 31.12.2015, ATS shall perform the following in case of all testing laboratories accredited to perform periodic measurements of stationary source emissions but not assessed so that it could be determined whether they also fulfil the requirements of SRPS CEN/TS 15675:
        - reduce the scope of accreditation or
        - withdraw accreditation (in case of those accredited testing laboratories performing only this type of testing).

CAB-related information about the Regulation on Portable Pressure Equipment

The Accreditation Body of Serbia hereby informs all accredited conformity assessment bodies and those seeking accreditation that, pursuant to published Regulation on Portable Pressure Equipment (published in the Official Gazette of the RS No. 30/2014 of 14.03.2014), the Regulation on Technical Norms for Portable Closed Vessels for Compressed, Liquid and Dilute Gases (“Official Journal of the SFRY“, Nos. 25/80 and 9/86, “Official Journal of the SRY“, Nos. 21/94, 56/95 and 1/03, and “Official Gazette of the RS“, No. 8/12) and Ordinance on Mandatory Atestation of Steel Propane-Butane Bottles with Valves (“Official Journal of the SFRY“, No. 44/87) shall be repealed with effect from the date of entry of this Regulation (1st June 2014). The Regulation prescribes (Article 16) that certificates of conformity issued on the basis of repealed regulations shall remain valid until the next periodic inspection, intermediate inspections or exceptional checks, but no later than 1st June 2019.

Having in mind the aforementioned, and after consulting with the Directorate for Dangerous Goods Transport, the Accreditation Body shall, from 1st June 2014, mark in the scopes of accreditation the said regulations as “repealed” in case of those CABs wishing to get accredited as per the new Regulation. Scopes of accreditation containing repealed regulations will remain valid until the finalisation of the accreditation procedure as per the new Regulation, but no later than 31.05.2015 when ATS will make decisions on reduction of the scope of accreditation or withdrawal of accreditation for those CABs that will still have in their scopes of accreditation reference to repealed regulations. In case of CABs that will still have reference to repealed regulations in their scopes of accreditation, but that do not wish to get accredited as per the new Regulation, ATS will, from 1st June 2014, make decisions on reduction of the scope of accreditation or withdrawal of accreditation.

Having in mind that the Regulation (Article 10) prescribes that accreditation as per SRPS ISO/IEC 17020 is one of the conditions to designate bodies, competence of all CABs wishing to get accredited for conformity assessment procedures as per the Regulation on Portable Pressure Equipment will be determined during initial assessments, reassessments and assessments for the purpose of extension of the scope of accreditation. When formulating scopes of accreditation CABs shall (under “reference documents” column) list, for each conformity assessment (CA) procedure (type of inspection), regulations, ADR/RID/ADN points describing CA procedures and specific standard(s) referring to ADR/RID/AND.

CABs wishing to get accredited as per SRPS ISO/IEC 17020 should meet the criteria for type A inspection bodies in order to become designated in keeping with the Regulation. The Directorate for Dangerous Goods Transport posted on its website (www.utot.gov.rs) an announcement for companies wishing to become designated for conformity assessment in case of portable pressure equipment and for interested parties wishing to apply in order to become designated.

Moreover, laboratories can be granted accreditation, as per the requirements of SRPS ISO/IEC 17025, to perform testing of portable pressure equipment, but it has to be mentioned that these laboratories cannot be designated by the Directorate for Dangerous Goods Transport given that such accreditation can confuse the market.

Opinion of the Ministry of Finance and Economy about the application of the Regulation on Personal Protective Equipment

We hereby inform our accredited conformity assessment bodies (CABs) that the Ministry of Finance and Economy, MFE (currently Ministry of Economy) published the opinion about the application of the Regulation on Personal Protective Equipment (PPE) – operation of the CABs after 1st July 2013.

For more information, please visit http://www.tehnis.privreda.gov.rs/en.html.

1st June 2013

In the first half of 2013, the Accreditation Body of Serbia (ATS) changed a series of documents and adopted the new management system documents in line with the requirements of the signed international agreements (EA MLA, ILAC MRA and IAF MLA) and obligations arising therefrom, change of the EA, ILAC and IAF documents, and the ATS wish to upgrade its management system and increase the efficiency of its operation.

With that end in view the following rules were changed:

- ATS-PA04, Rules for the Use of the Accreditation Symbol, Reference to Accreditation and ATS Status as a Signatory to the ЕА MLA, ILAC MRA and IAF MLA  in order to define the policy, conditions and rules for the use of the accreditation symbol and reference to accreditation, and the conditions and mode of use of the marks of international organisation for accreditation and reference to ATS status as a signatory to the said multilateral agreements; these Rules are fully in compliance with the requirements of ЕА-3/01 M: 2012, ILAC-R7:09/2009 and IAF ML 2:2011;

- ATS-PA05, Rules of Cross-frontier Accreditation defining the ATS policy applied when accrediting conformity assessment bodies with the head office outside the Republic of Serbia or CABs established in the Republic of Serbia having sites and/or key activities in another country, and the policy related to cooperation with other accreditation bodies in case of cross-frontier accreditation; these Rules are fully in compliance with the requirements of EA- 2/13 М:2012, ILAC-G21:09/2012 and Regulation (EC) No. 765/2008;

- ATS-PA03, Rules for Obtaining Acceptable Traceability of Measurement in order to be in compliance with ILAC- P10, ILAC Policy on Traceability of Measurement Results, and

- ATS-PA01, Rules of Accreditation that define the entire accreditation procedure, requirements to be met by CABs, rights and obligations of those participating in accreditation granting and maintenance. In addition to harmonisation with the changes in the management system documents and in order to increase the efficiency of the ATS operation and continue observance of the requirements of SRPS ISO/IEC 17011, the following periods of realisation of regular surveillance assessments were changed: “First regular surveillance assessment shall be carried out 6 to 9 months after the accreditation has been granted, second regular surveillance assessment shall be carried out 18 to 21 months after the accreditation has been granted, while the third one shall be carried out 30 to 33 months after the accreditation has been granted”. In accordance with the aforementioned, the time frame in case of realisation of reassessments was changed since this time frame require that reassessments shall be, as a rule, performed 6 months before the expiry of the accreditation validity period as specified in the changed Rules. Hence the plans of realisation of surveillance assessments and reassessments will be changed and accredited CABs will be informed thereof on time. The requirements related to the obligations of CABs and ATS were changed in line with the obligations arising from the signed agreements.

The Rules for the Use of ATS Logo ATS-PA07 were drafted in order to define the policy, conditions and use of the ATS logo and marks of international organisations for accreditation and reference to ATS status as a signatory to the multilateral agreements promoting equivalence of the accreditation systems.

In order to improve the operation of the ATS assessment teams and harmonise the assessor interpretations when performing assessments, ATS started collecting data related to the performed assessments by means of the special form entitled Evaluation of Performed Assessments (ATS-PR09-O02) that is available on the ATS website.

In the previous period ATS issued a larger number of the following guides governing specific fields of testing: ATS-UP27, Guides for the Accreditation of Microbiology Laboratories, and ATS-UP29, Guides for the Application of ISO/IEC 17025 when performing assessments of and granting accreditation to laboratories performing sensory testing, and ATS-UP32, Internal Control of Basic Metrological Parameters in Non-automatic Weighing Instruments between Two Calibrations providing description of the inspection procedure in case of basic metrological parameters affecting the measuring accuracy of non-automatic weighing instruments. The said documents are intended for both CABs and ATS assessors.

The document entitled ATS-UP28 Laboratory Accreditation Guide for Flexible Scopes specify the requirements for laboratories wishing to get accredited for flexible scopes of accreditation and procedures applied by ATS when granting accreditation to such laboratories. The said document is in compliance with EA 2/15 M. Flexibility means that laboratories can change the scope of accreditation they were granted accreditation for with no previous ATS assessments performed.

ATS grants accreditation to laboratories performing sampling and therefore the new Guide ATS-UP25 Accreditation of Sampling Activities stipulates the principles of assessment and accreditation of sampling activities performed by ATS.

All the said documents shall enter into force on the date of their adoption.

Information pertaining to the requirements to be met when measuring environmental noise levels

This information is intended for the assessors of the Accreditation Body of Serbia and laboratories performing noise measurement, and it resulted from the work of the ATS Task Force Group established to harmonise stands as regards the following requirements: monitoring of meteorological parameters when measuring noise, content of the noise test report and calibration frequency for calibrators used for noise measurement.

Monitoring of meteorological parameters when measuring noise:

Measurable meteorological parameters: temperature, barometric pressure, humidity and wind velocity are measured directly at the test location, whereas laboratories record on-site the presence of precipitation. Other meteorological parameters are as follows: wind direction and cloudiness are downloaded from the official website of the Hydrometeorological Service of Serbia (RHMZ). Parameters are measured by laboratories by using the equipment that was calibrated in line with the calibration programme that was put in place. This is necessary since meteorological parameters are essential for calculating the uncertainty of measurement of the measurement results.

Content of the noise test report:

Noise test report has to contain the elements provided under cl.5.10.2 of SRPS ISO/IEC 17025:2006 (Note: they are not contrary to the requirements of the Regulation on the Methods for Noise Measurement, Content and Scope of the Noise Test Report (“Official Gazette of the RS”, No. 72/2010), Article 3). Moreover, pursuant to the Regulation on Noise Measuring Methods, Content and Scope of the Noise Test Report (“Official Gazette of the RS”, No. 72/2010), a test report should also contain defined, i.e. measured meteorological parameters. The requested meteorological parameters are stipulated in standards used for environmental noise measuring - SRPS ISO 1996-1 (cl.8.2.1) and SRPS ISO 1996-2 (cl.12).

Calibration frequency for calibrators:

It is necessary to observe the recommendation made in SRPS ISO 1996-2 (cl. 5.2) as a document that served as a basis for noise measurement and that set the calibrator calibration frequency to be once a year. This once a year calibration frequency is not contrary to the requirements of the Regulation on the Conditions to Be Met by a Technical Organisation Performing Noise Measurement, and Documentation to Be Submitted together with an Application for Noise Measuring Authorisation (“Official Gazette of the RS”, No. 72/2010) that stipulates, in Article 3, that “the equipment has to be calibrated every two years by an accredited laboratory”.

9th April 2013

Information about the Regulation on Personal Protective Equipment

The Accreditation Body of Serbia hereby informs all accredited conformity assessment bodies that, pursuant to the published Regulation on Personal Protective Equipment (published in the Official Gazette of the RS Number 100 in 2011), certain regulations from this field governed by this Regulation shall be repealed with effect from the date of first application of this Regulation (1st July 2013). The Regulation prescribes that conformity certificates awarded on the basis of the repealed regulation shall remain valid until the expiry of the validity period, i.e. by 1st July 2013 at the latest as defined in the said regulation.

Having in mind the aforementioned, the Accreditation Body of Serbia will, from 1st July 2013, make decisions to reduce or withdraw accreditations to conformity assessment bodies that would list in their scopes of accreditation regulations that are no longer valid.

Competence of all CABs wishing to get accredited as per the Regulation on Personal Protective Equipment shall be determined during on-site assessments in case of initial assessments and reassessments or assessments for the purpose of extending the scope of accreditation.

The Accreditation Body of Serbia will, depending on the conformity assessment activities performed by CABs, grant accreditation to CABs in keeping with the requirements of the following standards:

  • For the conformity assessment activity defined by Article 11 of the Regulation (inspection of PPE type) – as per SRPS EN 45011 or SRPS ISO/IEC 17020;
  • For the conformity assessment activity defined by Article 12 of the Regulation (conformance with PPE type on the basis of internal production control and inspected testing of products at random intervals) – as per SRPS EN 45011 or SRPS ISO/IEC 17020;
  • For the conformity assessment activity defined by Article 13 of the Regulation (conformance with PPE type on the basis of the production process quality guarantee-production quality assurance) – as per SRPS ISO/IEC 17021.

Those CABs wishing to get accredited as per SRPS ISO/IEC 17020 should meet the requirements for “type A” inspection bodies in order to be designated in line with the Regulation.

Furthermore, laboratories can be awarded accreditation in accordance with SRPS ISO/IEC 17025 in case of testing of personal protective equipment for the needs of interested parties, whereas only designated CABs can issue the conformity certificates referred to in Articles 11-13 of the Regulation.

The list of regulations repealed in accordance with Article 24 of the Regulation on Personal Protective Equipment:

  1. Decree on Mandatory Attestation of Protective Helmets Used in Industry (“Official Journal of the SFRY” Nos. 4/82 and 43/82);
  2. Decree on Mandatory Attestation of Fire Protection Helmets (“Official Journal of the SFRY” No. 67/86);
  3. Decree on Mandatory Attestation of Respiratory Protective Equipment (“Official Journal of the SFRY” No. 49/87);
  4. Decree on Mandatory Attestation of Climbing hooks for Wooden Poles and Conditions to be Met by Organisations of Associated Labour Authorised to Attest These Products (“Official Journal of the SFRY” No. 67/89);
  5. Decree on Mandatory Attestation of Protective Belts and Conditions to be Met by Organisations of Associated Labour Authorised to Attest These Products (“Official Journal of the SFRY” No. 67/89);
  6. Regulation on Technical and Other Requirements for Fire Protection Helmets (“Official Gazette of the RS” No. 74/09);
  7. Regulation on Technical and Other Requirements for Personal Protective Equipment (“Official Gazette of the RS” No. 56/09), other than a provision in Article 2, point 10) of the regulation pertaining to helmets and visors for two or three wheel motor vehicle drivers.

Information about the content of the assessment report/calibration certificate when a laboratory has to state compliance with specifications

(based on ILAC-G8:03/2009, Guidelines on the Reporting of Compliance with Specification)

The information is intended for assessors of the Accreditation Body of Serbia and laboratories that need to provide statements of compliance with specifications in their test reports/calibration certificates.

The following references from ILAC-G8:03/2009, Guidelines on the Reporting of Compliance with Specification enable/explain coherent application of specific requirements of SRPS ISO/IEC 17025:

- For testing laboratories, ISO/IEC 17025:2005 (clause 5.10.3.1 b) requires that “the test report shall, where necessary for the interpretation of the test results include…, where relevant, a statement of compliance/non-compliance with requirements and/or specification”.;

- For calibration laboratories, ISO/IEC 17025:2005 (clause 5.10.4.2) requires that “if a statement of compliance with a specification is made, this shall identify which clauses of the specification are met or not met”. It is permissible to omit the measurement result and its uncertainty from the report as long as they are retained for possible future reference.

Statements of compliance with requirements and/or specifications shall not be considered opinions or interpretations in terms of SRPS ISO/IEC 17025. Therefore, when a laboratory reports such compliance in its test reports/calibration certificates, it has to be properly defined (e.g. statement of compliance with specification, conclusion, etc, but not “opinion”, “interpretation” or “opinion and interpretation”).

When laboratories provide statements of compliance with requirements and/or specifications in their test reports/calibration certificates, these test reports/calibration certificates shall, among other things, contain the following:

  • Test/calibration results with expanded uncertainty;
  • Coverage probability for expanded uncertainty;
  • A statement of compliance should not be reported in a way where it could be confused with inspection or product certification and it can only pertain to a test/calibration item, and
  • Source of specification.

When a specification describes an interval with an upper and lower limit, a statement of compliance or non-compliance should only be made where the ratio of the expanded uncertainty interval to the specified interval is reasonably small and fit for purpose (meaning that the laboratory should be able to meet the needs of the customer).

Measurement results can be stated without measurement uncertainty only when a specification or legal requirements require so (e.g. when it is stated that measurement uncertainty has been accounted for when setting the limits).

Stating compliance with specification for a single quantity

When a measurement result, including extended uncertainty, is compared with the specification interval (upper and lower specification limit) 4 cases can be defined (Figure 1):

  • Case 1: measurement result with expanded uncertainty is below the upper specification limit or above the lower specification limit;
  • Case 2: measurement result is below the upper specification limit or above the lower specification limit, but the interval of expanded uncertainty is outside the specification limit;
  • Case 3: measurement result is above the upper specification limit or below the lower specification limit, but the interval of expanded uncertainty includes part of the specification interval;
  • Case 4: measurement result with expanded uncertainty is above the upper specification limit or below the lower specification limit.

Figure 1. Compliance with specification for upper and lower limits

In case 1 compliance with the specification can be stated as “Compliance” or “Compliance – The measurement result is within (or below) the specification limit when the measurement uncertainty is taken into account with a 95% coverage probability for extended uncertainty”.
In case 4 noncompliance with the specification can be stated as  “Non-compliance – The measurement result is outside (above upper or below lower) the specification limit when the measurement uncertainty is taken into account with a 95% coverage probability”.
 
In cases 2 and 3 it is not possible to state compliance or non-compliance. In Case 2 it is possible to indicate “It is not possible to state compliance using a 95 % coverage probability for the expanded uncertainty although the measurement result is below the upper limit”. Only in case of a clear need for the statement of compliance/noncompliance (e.g. legal requirement), case 2 can be reported as follows “Compliance – compliance cannot be confirmed with a 95 % coverage probability for expanded uncertainty which means that the measurement result can be outside (above upper or below lower) the specification limit”, while in case 3 this can be reported as “Noncompliance – noncompliance cannot be confirmed with a 95 % coverage probability for expanded uncertainty which means that the measurement result can be inside (below upper or above lower) the specification limit”.
 
In case of a measurement result that is equal to the specification limit the procedure will follow that of case 3. If a laboratory is using a coverage probability other than a 95% coverage probability, then a statement of compliance/noncompliance with specification has to be harmonised given the used coverage probability.

Stating compliance with specification involving multiple quantities
 
If the evaluation of compliance with specification comprises more quantities, each measurement value should be evaluated independently. The result of each evaluation should be reported.
 
An overall evaluation of compliance with requirements or specification may be formulated in one of the following ways, or by combining them:

  • “All measured values comply with the specification limit(s)” or “The item/sample complies with the requirements”. This covers situations where all measurements comply with specification (Case 1 of Fig.1);
  • “For some of the measured values it is not possible to make a statement of compliance with specification”. This covers situations where some of the measurements demonstrate neither compliance nor non-compliance with specification (Case 2 and 3 of Fig.1).
  • “Some of the measured values do not comply with specifications” or “The item/sample does not comply with the requirements”. This covers situations where one or more measurements are in non-compliance with specifications (Case 4 of Fig.1).

EURACHEM is pleased to announce the publication of the Third Edition of the Eurachem/CITAC Guide "Quantifying Uncertainty in Analytical Measurement". The new version is closely consistent with the Second edition, and adds information based on developments in uncertainty estimation and use since 2000. The additional material provides:
-    Expression of uncertainty near zero;
-    Monte Carlo methods for uncertainty evaluation;
-    Improved guidance on the use of proficiency testing data:
-    Improved guidance on the assessment of compliance of results with measurement uncertainty.
The revised guide can be downloaded from EURACHEM website at www.eurachem.org.

A Working Group of the Accreditation Body of Serbia was established in order to take a stand as regards the description of the measuring ranges in the field of testing of building materials and the following conclusions were made:
 - in case when a standard testing method is used to define a measuring range that a laboratory can meet, the measuring range shall not be presented in the scope of accreditation;
- in case when a standard testing method is used to define a measuring range that a laboratory cannot meet in its entirety, the measuring range shall be described in accordance with the laboratory capabilities;
- in case of physical quantities that are the result of a direct measuring the measuring range shall be described (for example: mass, force (press range that is adequate for that testing), length, temperature (e.g. in case of asphalt, pressure).

When granting accreditation to testing laboratories performing periodic measurements of stationary source emissions the Accreditation Body of Serbia also assesses fulfillment of the requirements of SRPS CEN/TS 15675. With that end in view the Accreditation Body of Serbia published the document entitled ATS-UP20 Guidelines for the Application of SRPS CEN/TS 15675 When Assessing Testing Laboratories that contains the description of the ATS policy related to the application of this technical specification.

On 14th July 2011, the Accreditation Body of Serbia accepted the proposal made by the Electromagnetic Compatibility (EMC) Working Group that pertained to the description of the scope of accreditation in this field.

The annex contains the examples of how to describe the scope of accreditation that will become an integral part of the document entitled ATS-UP03, Guidelines for Describing the Accreditation Scopes of Testing Laboratories.

All accredited testing laboratories in this field need to harmonise their scopes in line with the adopted mode of description thereof by 01.01.2012 at the latest. When submitting documentation needed for the implementation of surveillance assessments, laboratories shall submit a proposal to update the scope that will be in line with the decisions that were adopted. When making decisions on accreditation ATS will update the scopes of accreditation that had already been granted.
