Using round Robin Test Results for the Accreditation of Laboratories in the Field of Building Acoustics in Germany
The assessment procedure currently used for the accreditation of building acoustics laboratories is given in the standard ISO 140-2. It is based on the deviations between values obtained in the new laboratory and round robin results whereupon the number of third-octave values outside of the critical differences is simply counted. A new procedure is proposed which additionally accounts for the amount of deviation from the round robin mean value. Thus, it can be considered as a refined continuously scaled version of the current procedure. The new method has been checked by applying it to the data from a round robin survey of a heavy test wall. Besides the comparison between individual laboratory results and round robin mean results, an additional single measurement, carried out in each laboratory, is proposed to verify the results.
