Anotation

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. LIEC 60974-4:2025 specifie les procedures dessai pour linspection periodique, afin dassurer la securite electrique apres reparation. Ces procedures dessai sappliquent egalement a la maintenance. Le present document sapplique aux sources de courant pour le soudage a larc et les techniques connexes concues conformement a lIEC 60974-1 ou lIEC 60974-6. Les equipements auxiliaires independants concus conformement a dautres parties de lIEC 60974 peuvent etre soumis a lessai conformement aux exigences correspondantes de la presente partie de lIEC 60974. Le present document inclut des exigences concernant les sources de courant de soudage a larc sur batterie, qui figurent a lAnnexe D. NOTE 1 La source de courant de soudage peut etre soumise a lessai avec tout equipement auxiliaire monte qui peut influencer les resultats dessai. Le present document ne sapplique pas aux essais des nouvelles sources de courant ou aux groupes electrogenes. NOTE 2 Pour une source de courant qui nest pas concue conformement a lIEC 60974-1, voir Annexe C. Cette quatrieme edition annule et remplace la troisieme edition parue en 2016. Elle constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - exemple de mesurages en reference a lEN 50699, - prise en compte de lequipement de mesure en reference a la serie IEC 61557, - autres determinations de la tension a vide pour le materiel de soudage construit conformement a lIEC 60974-1:1998 et lIEC 60974-1:1998/AMD1:2000 ou une edition anterieure; - nouvelle Annexe D contenant des informations supplementaires a prendre en compte lors des essais des sources de courant de soudage sur batterie et des chargeurs connectes.
