IEC 60317-4 pdf download Specifications for particular types of winding wires – Part 4: Solderable polyurethane enamelled round copper wire, class 1 30
1 Scope
This International Standard 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.
NOTE A modified resin is a resin that has undergone a chemical change, or contains one or more additives toenhance certain performance or application characteristics.
Class 130 is a thermal class that requires a minimum temperature index of 130 and a heatshock temperature of at least 155 °c.
The temperature in degrees Celsius corresponding to the temperature index is not necessarilythat at which it is recommended that the wire be operated and this will depend on manyfactors,including the type of equipment involved.
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-O-1.
