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 14: Equipment for testing the safety of electrical equipment of machinery (IEC 61557-14:2023)

IEC 61557-14:2023 defines special requirements for test and measurement equipment used to determine the electrical safety of electrical equipment of machinery in accordance with IEC 60204-1.
This International Standard is to be used in conjunction with IEC 61557-1:2019.
IEC 61557-14:2023 cancels and replaces the first edition published in 2013. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) clarifying the introduction;
b) replaced "dielectric strength" by "voltage test";
c) requirement for maximum output current has been added in 4.2.6.1;
d) tripping time at electrical switching activated by two-hand operation has been added in 4.2.6.1;
e) additional time limiting capability for the protection against electric shock for test persons and bystanders in 4.2.6.2;
f) updated references for safety testing;
g) alignment of the structure with that of the whole IEC 61557 series.
