EN 60974-4:2011

Arc welding equipment - Part 4: Periodic inspection and testing

IEC 60974-4:2010 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 part of IEC 60974 may be tested in accordance with relevant requirement of this part of IEC 60974. This second edition cancels and replaces the first edition published in 2006. It constitutes a technical revision. The main significant technical changes with respect to the previous edition are the following: - title is amended; - scope is extended to equipment designed in accordance with IEC 60974-6; - complementary instructions from the manufacturer shall be followed; - qualification of test personnel is clarified (see 4.1); - plasma cutting power sources are excluded from no-load voltage test (see 5.6); - voltage reducing device functional test is simplified (see 6.3); - supply voltage is recorded in test report (see 7.1).

Matériel de soudage à l'arc - Partie 4: Inspection et essais périodiques

La CEI 60974-4:2010 spécifie les procédures d'essai pour l'inspection périodique, afin de garantir la sécurité électrique après réparation. Ces procédures d'essai s'appliquent également à la maintenance. La présente norme s'applique aux sources de courant pour le soudage à l'arc et les techniques connexes conçues conformément à la CEI 60974-1 ou la CEI 60974-6. Les équipements auxiliaires indépendants conçus conformément à une autre partie de la CEI 60974 peuvent être soumis aux essais conformément aux exigences correspondantes de la présente partie de la CEI 60974. Cette seconde édition annule et remplace la première édition parue en 2006. Elle constitue une révision technique. Les modifications majeures par rapport à l'édition précédente sont les suivantes: - changement du titre; - le domaine d'application est élargi au matériel conçu conformément à la CEI 60974-6; - les instructions complémentaires du fabricant doivent être respectées; - la qualification du personnel effectuant les essais est clarifiée (voir 4.1); - les sources de courant pour coupage plasma sont exclues de l'essai de la tension à vide (voir 5.6); - l'essai fonctionnel du dispositif réducteur de tension est simplifié (voir 6.3); - la tension d'alimentation est enregistrée dans le rapport d'essai (voir 7.1).

Oprema za obločno varjenje - 4. del: Perodični pregledi in preskusi (IEC 60974-4:2010)

Ta del IEC 60974 določa preskusne postopke za periodične preglede in, po popravilu, za zagotavljanje električne varnosti. Ti preskusni postopki veljajo tudi za vzdrževanje. Ta standard velja za vire napajanja za obločno varjenje in povezane procese, zasnovane v skladu z IEC 60974-1 ali IEC 60974-6. Samostojna pomožna oprema, projektirana v skladu z drugimi deli IEC 60974, se lahko preskuša v skladu z ustreznimi zahtevami tega dela IEC 60974.
OPOMBA 1: Vir napajanja za varjenje se lahko preskuša s katero koli nameščeno pomožno opremo, ki lahko vpliva na rezultate preskusa.
Ta standard ne velja za preskušanje novih virov napajanja ali virov napajanja, ki jih poganja motor.
OPOMBA 2: Za vir napajanja, ki ni vgrajen v skladu z IEC 60974-1, glej dodatek C.
