2012年7月26日 · The current standard for sound level meters, IEC 61672, is published in three parts. Here our explanation of IEC 61672 and what these parts mean for sound level meters. The first part, Part 1, details the performance characteristics that a Class 1 or Class 2 sound level meter should have.

‘IEC 61672-2 – ‘Pattern-evaluation tests’ provides details of the full tests necessary to verify conformance to all mandatory specifications given in IEC 61672-1 for a particular model of instrument, with the aim of ensuring that all laboratories use consistent methods to perform pattern-evaluation testing.

To satisfy most regulations, new meters should meet the standard IEC 61672 (or the British Standard equivalent BS EN 61672) to either Class 1 or Class 2. There are other standards for the Calibrator, for noise dosimeters, personal sound exposure meters, octave band filters and so on.

IEC 61672-3:2013 describes procedures for periodic testing of time-weighting, integrating-averaging, and integrating sound level meters that were designed to conform to the class 1 or class 2 specifications of the second edition of IEC 61672-1.

This standard, in conjunction with IEC 61672-2, cancels and replaces IEC 60651, Sound level meters , and IEC 60804, Integrating-averaging sound level meters . The text of this standard is based on the following documents:
