The first key comparison in the area of vibration organized under the auspices of the Consultative Committee for Acoustics, Ultrasound and Vibration (CCAUV) and piloted by the Physikalisch-Technische Bundesanstalt (PTB) was carried out between January 2000 and June 2001. Twelve national metrology institutes (NMIs) from the five regional metrology organizations APMP, COOMET, EUROMET, SADCMET and SIM participated. On the basis of thorough investigations of amplitude linearity, long-time stability and other performance characteristics, the pilot laboratory had selected two different reference accelerometers (back-to-back and single-ended) as transfer standards.
