This part of IEC 62135 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.
Resistance welding equipment type tested in accordance with, and which has met the requirements of, this standard, is deemed to be in compliance for all applications.
The frequency range covered is from 0 Hz to 400 Ghz.
This product EMC standard for resistance welding equipment takes precedence over all aspects of the generic standards and no additional EMC tests are required or necessary.
Typical allied processes are resistance hard and soft soldering or resistance heating achieved by means comparable to resistance welding equipment.
Limit values are specified for only part of the frequency range.
Resistance welding equipment are classified as class A and class B equipment.
This part of IEC 62135 specifies
-
test methods to be used in conjunction with CISPR 11 to determine radiofrequency (RF) emission;
-
relevant standards and test methods for harmonic current emission, voltage fluctuation and flicker.
The limits in this standard cannot, however, provide full protection against interference to radio and television reception when the resistance welding equipment is used closer than 30 m to the receiving antenna(e).
In special cases, when highly susceptible apparatus is being used in close proximity, additional mitigation measures are sometimes employed to further reduce the electromagnetic emissions.
This part of IEC 62135 also defines immunity requirements and test methods for continuous and transient, conducted and radiated disturbances including electrostatic discharges.
These requirements do not, however, cover extreme cases which are extremely rare.
