BS EN 62135-2:2008 Resistance welding equipment. Electromagnetic compatibility (EMC) requirements
BS EN 62135-2:2008 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. The frequency range covered is from 0 Hz to 400 GHz.
Resistance welding equipment type tested in accordance with, and which has met the requirements of, this standard, shall be deemed to be in compliance for all applications.
BS EN 62135-2 takes precedence over all aspects of the generic standards and no additional EMC tests are required or necessary.
BS EN 62135-2 specifies:
- test methods to be used in conjunction with CISPR 11 to determine radiofrequency (r.f.) emission
- relevant standards and test methods for harmonic current emission, voltage fluctuation and flicker.
It also defines immunity requirements and test methods for continuous and transient, conducted and radiated disturbances including electrostatic discharges.
This standard does not define safety requirements.
BS EN 62135-2:2008 supersedes BS EN 50240:2004 which is withdrawn.
