"This document is titled as a calibration standard even though the method is typically conducted in a testing laboratory. While the sound pressure level measurements and distances associated with this method are traceable, the sound power level calibration results are not directly traceable to national standards of measure in a strict metrological sense. Testing laboratories performing this method are not expected to meet all requirements normally associated with a calibration laboratory."
