scope:

IEC 62135-2:2015 is applicable to equipment for resistance welding and allied processes which are connected to mains supplies with rated voltages up to 1 000 V a.c. r.m.s. This standard does not define safety requirements. This second edition cancels and replaces the first edition published in 2007 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - update of the applicable limits related to the updated reference to CISPR 11; - exclusion of the use of narrow band relaxations for RF emission limits; - update of the applicable limits for harmonics and flicker related to the updated reference to IEC 61000-3-11 and IEC 61000-3-12; - update of the requirements for voltage dips related to the updated reference to IEC 61000-4-11 and IEC 61000-4-34; - inclusion of symbols to indicate the RF equipment class and restrictions for use; - inclusion of EM field immunity test for frequency from 1,4 GHz to 2,7 GHz; - inclusion of emission limits for class B resistance welding equipment magnetic fields between 150 kHz and 30 MHz.
