    Project Details


    International comparison between 37 laboratories in 16 countries on calibration of Pistonphones and Sound Calibrators organized under EA/C2 (European co-operation for Accreditation).
    Project leader and pilot laboratory.
    2 sets of pistonphones (B&K type 4228) and Sound Calibrators (B&K type 4231) was calibrated in January 1998 and has since then circulated among the participating laboratories. An intermediate recalibration took place in August 1998 and the circulation was finished in January 1999.
