Electrical safety in low voltage distribution systems up to 1 000 V AC and 1 500 V DC - Equipment for testing, measuring or monitoring of protective measures - Part 16: Equipment for testing the effectiveness of the protective measures of electrical equipment and/or medical electrical equipment

Scope

IEC 61557-16:2023 specifies the requirements applicable to the performance for test and measurement equipment in order to determine the effectiveness of the protective measures for electrical equipment and/or medical electrical equipment described in IEC 62353.

This International Standard is to be used in conjunction with IEC 61557-1:2019.

IEC 61557-16:2023 cancels and replaces the first edition published in 2014. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a) splitting of uncertainty requirements for medical and non-medical electrical equipment in 4.2.1;

b) addition of a definition of ranges with defined uncertainty in 4.2.1 to 4.2.7;

c) addition of an optional measuring device (MD) for non-medical devices in 4.2.1;

d) addition of a limitation of the maximum intrinsic uncertainty for medical applications at leakage current in 4.2.1;

e) change of 4.2.3 from test sockets to sockets for service purposes;

f) addition of a warning in the operating instructions;

g) integration of former 6.3 into 6.2;

h) update of Table 1;

i) alignment of the structure with that of the whole IEC 61557 series.
