IEC 60974-4:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60974-4:2025 specifies test procedures for periodic inspection and, after repair, to ensure electrical safety. These test procedures are also applicable for maintenance. This document 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 can be tested in accordance with relevant requirements of this part of IEC 60974. This document includes requirements for battery-powered arc welding power sources, which are given in Annex D. NOTE 1 The welding power source can be tested with any ancillary equipment fitted that can affect the test results. This document is not applicable to testing of new power sources or engine-driven power sources. NOTE 2 For a power source not built in accordance with IEC 60974-1, see Annex C. This fourth edition cancels and replaces the third edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - examples for the measurements in respect of EN 50699, - consideration of measuring equipment in respect of IEC 61557 series, - more determinations of no-load voltage for welding equipment built according to IEC 60974-1:1998 and IEC 60974-1:1998/AMD1:2000 or earlier, - new Annex D providing additional information to be considered when testing battery-powered welding power sources and connected chargers.
