IEC 60051-6:2017 applies to direct acting indicating analogue electrical measuring ohmmeters (impedance meters) and conductance meters. This document also applies to some non-interchangeable accessories of ohmmeters (impedance meters) and conductance meters. This fifth edition cancels and replaces the fourth edition published in 1984. 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 IEC 60051-1 and IEC 60051-9; b) addition of Annex A to specify the nonconformity classification of test items.
