Specifies test methods to be used in conjunction with CISPR 11 to determine radiofrequency emission; relevant standards and test methods for harmonic current emission, voltage fluctuation and flicker. Also defines immunity requirements and test methods for continuous and transient, conducted and radiated disturbances including electrostatic discharges.
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.
