IEC60051-5:2017 applies to direct acting indicating phase meters, power factor meters and synchroscopes having an analogue display.This document also applies to non-interchangeable accessories (as defined in 3.1.23 of IEC60051-1:2016) used with phase meters, power factor meters and synchroscopes.This document also applies to a phase meter or power factor meter whose scale marks do not correspond directly to its electrical input quantity, provided that the relationship between them is known.This fifth edition cancels and replaces the fourth edition published in 1985. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:a) updating of content in line with new editions of IEC60051-1 and IEC60051-9;b) addition of Annex A to specify the nonconformity classification of test items.
