Description of BS EN IEC 60317-18:2020 2020
IEC 60317-18:2020 is available as
IEC
60317-18:2020 RLV which contains the International Standard and
its Redline version, showing all changes of the technical content
compared to the previous edition.
IEC 60317-18:2020 specifies the requirements of enamelled
rectangular copper winding wires of class 120 with a sole coating
based on polyvinyl acetal or polyvinyl formal resin, which can be
modified provided it retains the chemical identity of the original
resin and meets all specified wire requirements NOTE 1 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. NOTE 2 Polyvinyl acetate is a general name for a
family of thermoplastic vinyl resins produced by the condensation
of polyvinyl alcohol with an aldehyde. Examples are polyvinyl
acetal, polyvinyl formal and polyvinyl butyral. The range of
nominal conductor dimensions covered by this document is: - width:
min. 2,0 mm max. 31,5 mm; - thickness: min. 0,80 mm max. 10,0 mm.
Wires of grade 1 and grade 2 are included in this specification and
apply to the complete range of conductors. The specified
combinations of width and thickness as well as the specified ratio
width/thickness are given in IEC 60317-0-2. This fourth edition
cancels and replaces the third edition published in 2004 and
Amendment 1:2009. This edition constitutes a technical revision.
This edition includes the following significant technical changes
with respect to the previous edition: - modification of the Scope
(Clause 1); - revision to thermal class designation from 105 to 120
in 3.2.2; - renaming of stretching test to adherence test, and
modification to the requirements in 8.2; - revision to the
