Scope

<!-- NEW! -->IEC 61557-5:2019 is available as <a href="https://webstore.iec.ch/publication/65554">IEC 61557-5:2019 RLV</a> which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.</br></br>IEC 61557-5:2019 specifies the requirements applicable to measuring equipment for measuring the resistance to earth using an AC voltage. IEC 61557-5:2019 cancels and replaces the second edition published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:

a) definitions and symbols in Clause 3 modified;

b) subclauses in Clause 4 restructured and aligned with other parts of the series;

c) limits for reduced voltages 25 V RMS or 35 V peak removed from 4.5;

d) requirements for clamps added;

e) marking for rated voltages to earth and measurement category added to Clause 5;

f) warning about absence of hazardous voltage added in Clause 5;

g) the term "percentage operating uncertainty" replaced by "operating uncertainty" in Clause 6;

h) equation for uncertainty corrected in Table 1;

i) new Annex A on test measurements with loop clamps added.
