IEC TR 61000-4-37:2016 outlines a typical test procedure for harmonic analysis in systems comprising tests apparatus designed to comply with IEC 61000-4-7, and products designed to comply with IEC 61000-3-2 and/or IEC 61000-3-12. The test procedure is intended to provide a systematic guidance suitable for use by manufacturers, end users, independent test laboratories and other bodies, for the purpose of determining the applicable compliance status within a wide range of harmonic current emissions. It is not intended as a replacement for type testing of harmonic analyzers, nor does it check all of the parameters specified in IEC 61000-4-7, IEC 61000-3-2, and IEC 61000-3-12.
