IEC 60974-10-2020 pdf free download – Arc welding equipment – Part 10: Electromagnetic compatibility (EMC) requirements.
This part of lEC 60974 is applicable to equipment for arc welding and allied processes,including power sources and ancillary equipment,for example wire feeders，liquid coolingsystems, arc striking and stabilizing devices and chargers for battery powered equipment.
NOTE 1 Allied processes are, for example,plasma cutting and arc stud welding.
NOTE 2 This document does not specify basic safety requirements for arc welding equipment such as protectionagainst electric shock,unsafe operation, insulation coordination and related dielectric tests.
Arc welding equipment containing a radio receiver or transmitter is within the scope of thisdocument.
The radiated emission requirements in this document are not intended to be applicable to theintentional transmissions from a radio transmitter as defined by the lTU nor to any spuriousemissions related to these intentional transmitters.
This document specifies
a) applicable standards and test methods for radio-frequency (RF) emissions;
b) applicable standards and test methods for harmonic current emission, voltage fluctuations and flicker;
c)immunity requirements and test methods for continuous and transient,conducted and radiated disturbances including electrostatic discharges;
d) additional requirements for equipment powered by internal or external batteries (Annex D);
e) additional requirements for equipment containing radio frequency transmitters/receivers (Annex E).
Arc welding equipment type tested in accordance with,and which has met the requirementsset in, this document is considered to be in compliance for all applications.
