Arc welding equipment - Part 4: Periodic inspection and testing
IEC 60974-4:2016 specifies test procedures for periodic inspection and, after repair, to ensure electrical safety. These test procedures are also applicable for maintenance. This standard is applicable to power sources for arc welding and allied processes designed in accordance with IEC 60974-1 or IEC 60974-6. Stand-alone ancillary equipment designed in accordance with other parts of IEC 60974 may be tested in accordance with relevant requirements of this part of IEC 60974. This third edition cancels and replaces the second edition published in 2010. It constitutes a technical revision. The main significant technical changes with respect to the previous edition are the following:- With regard to basic standards the term "leakage current" has been replaced by "touch current" and "protective conductor current".- Measurements of circuits connected in a non-galvanic way shall be tested according to the information of the manufacturer.- The order of the chapters dealing with measurements to be carried out has been changed.- The example test report in Annex B has been adapted.
