DMDM calibration and measurement capabilities in the field of acoustics were published
Notices
The International Bureau of Weights and Measures (BIPM) published calibration and measurement capabilities (CMCs) of the Directorate of Measures and Precious Metals (DMDM) for the field of acoustics, ultrasound and vibrations (AUV), subfield: sound in air.
On 27th February 2014 BIPM recognised the CMCs for 12 DMDM calibration services pertaining to calibration of laboratory standard microphones (LS1P and LS2P) by using primary reciprocity calibration method.
CMC List of DMDM is available on the BIPM website: (http://kcdb.bipm.org/AppendixC/country_list_search.asp?page=1&pge=1&CountSelected=RS&type=AUV).
