Product Details
NOTE A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics.
The range of nominal conductor diameters covered by this document is:
- Grade 1: 0,250 mm up to and including 3,150 mm;
- Grade 2: 0,250 mm up to and including 5,000 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-3:2008 and IEC 60317-0-3:2008/AMD1:2013. This fourth edition cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- new 3.2.2 containing general notes on winding wire, formerly a part of the Scope;
- revision to Clause 11 to take into account intermediate nominal conductor diameters;
- revision to Clause 7 to indicate that the springiness test is inappropriate.
- revision to Clause 16 to specify only the percentage of extractable matter and the minimum retained dielectric breakdown voltage.
