PRIMARY CALIBRATION OF ACCELEROMETERS AND MICROPHONES IN DENMARK

摘要

Until this year no officially recognized laboratory for primary calibrations within the field of acoustics existed in Denmark. Therefore all laboratories wanting traceable calibrations had to get traceability by having their standards calibrated abroad, mostly at PTB in Germany or at NIST in Washington DC, USA. Recently the Danish Primary Laboratory of Acoustics (DPLA) has been established as primary laboratory for calibration of accelerometers and microphones and accredited to perform calibrations and issue calibration certificates as a service to clients. DPLA is an independent department within Bruel & Kjaer Industries and cooperates with the Acoustics Laboratory at the Technical University of Denmark, Lyngby. Mutual recognition of calibrations and laboratories is ensured by a multilateral agreement between the following countries: Denmark, Finland, France, Germany, Italy, The Netherlands, Sweden, Switzerland and the United Kingdom. The agreement is made within the framework of WECC (Western European Calibration Cooperation.
