European Standard

17.220.20     29.080.01     29.240.01  


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;
d) tripping time at electrical switching activated by two-hand operation has been added in;
e) additional time limiting capability for the protection against electric shock for test persons and bystanders in;
f) updated references for safety testing;
g) alignment of the structure with that of the whole IEC 61557 series.
