    Abstract - (Show below) - (Hide below)

    Provides details of the tests necessary to verify conformance to all mandatory specifications for sound levels meters. Identical with and reproduced from IEC 61672-2:2003.

    Scope - (Show below) - (Hide below)

    This part of IEC 61672 provides details of the tests necessary to verify conformance to allmandatory specifications given in IEC 61672-1:2002 for conventional sound level meters,integrating-averaging sound level meters and integrating sound level meters. Patternevaluation tests apply for each channel of a multi-channel sound level meter, as appropriate.Tests and test methods are applicable to class 1 and class 2 sound level meters. The aim is toensure that all testing laboratories use consistent methods to perform pattern evaluation tests.
