Foreword
The text of document 26/307/FDIS, future edition 3 of IEC 60974-1, prepared by IEC TC 26, Electric
welding, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as
EN 60974-1 on 2005-10-01.
This European Standard supersedes EN 60974-1:1998 + A1:2000 + A2:2003.
The significant changes with respect to EN 60974-1:1998 are the following:
– the scope includes relationship to other parts of EN 60974;
– environmental conditions were changed (see 4.a and 4.e);
– conformity of components is given (see 5.3);
– the sequence of type test was changed (see 5.4);
– more precise requirements for measuring the no-load voltage during routine test are given
(see 5.5d);
– creepage values for printed circuit boards are implemented (see Table 2);
– requirements for enclosures are changed (see 6.2.1);
– requirements for primary leakage current are included (see 6.3.7 and Annex N);
– requirements for engine driven power sources are changed (see 7.1.2 and 7.3.2);
– requirements for supply circuit terminals are changed (see 10.4.3 and 10.4.4);
– requirements for cable anchorage are changed (see 10.5);
– requirements for coupling devices are changed (see 10.9);
– standard characteristic for plasma welding is included (11.2.6);
– requirements for welding cables are added (see 11.7);
– requirements for plastic material used as enclosure materials are added (see 14.2.1);
– requirements for manual handling are added (see 14.3.2);
– existing ISO symbols and labels are taken into account (see 15.3 and 17.2).
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2006-07-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2008-10-01
Annex ZA has been added by CENELEC.
