BS EN 50504 Validation of arc welding equipment specifies validation methods for arc welding equipment constructed and used to the accuracy specified in BS EN 60974-1 or other equivalent standards BS EN 50504 applies to:
Arc welding power sources wire feeders welding instrumentation.
BS EN 50504 is not applicable to arc striking and stabilizing device. Calibration, verification and validation of equipment for other welding processes and ancillary equipment which may affect the quality of the weld, e.g. flow gauges, thermocouples, robots and manipulators are given in EN ISO 17662 .
