BS IEC 60317-4-2015 pdf free download – Specifications for particular types of winding wires Part 4: Solderable polyurethane enamelled round copper wire, class 130.
This part of lEC 60317 specifies the requirements of solderable enamelled round copperwinding wire of class 130 with a sole coating based on polyurethane resin，which may bemodified provided it retains the chemical identity of the original resin and meets all specifiedwire requirements.
NOTEA modfied resin is a resin that has undergone a chemical change,or contains one or more additives toenhance certain performance or application characteristics.
The range of nominal conductor diameters covered by this standard is:-Grade 1:0,018 mm up to and including 2,000 mm;
-Grade 2: 0,020 mm up to and including 2,000 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013.
