What is BS EN IEC 60317-18 about?
BS EN IEC 60317-18 is the 18th part of multi-series that specifies the requirements of enamelled rectangular copper winding wires of class 120 with a sole coating based on polyvinyl acetal resin, which can be modified provided it retains the chemical identity of the original resin and meets all specified wire requirements.
The range of nominal conductor dimensions covered by this document is:
- Width: minimum: 2.0 mm, maximum: 31.5 mm
- Thickness: minimum: 0.80 mm, maximum: 10.0 mm
Who is BS EN IEC 60317-18 for?
BS EN IEC 60317-18 on particular type of polyvinyl acetal enamelled rectangular copper wire is relevant to:
- Copper wire manufacturers
- Manufacturers of applications that require electrical transference
- Electrical engineers
- Mechanical engineers
Why should you use BS EN IEC 60317-18?
Polyvinyl acetals the 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.
BS EN IEC 60317-18 provides basic specifications and test methods that aid in standardizing the quality of PVAc enamelled round copper wending wires.
BS EN IEC 60317-18 includes wires of grade 1 and grade 2 and applies to the complete range of conductors.
BS EN IEC 60317-18 provides information on appearance, dimensions and physical properties of wending wires including elongation, durability, resistance, and pliability
Compliance with BS EN IEC 60317-0-18 is beneficial as you will be able to ensure, through standardised methods, the extent of the materials’ resistance to bending, flammability at elevated temperatures, humidity resistance, and resistance to chemical and biological effects.
More importantly, the chemical composition of the original resin will remain intact, imparting high operational efficiency to the copper wire.
This will enable you to make the right production decisions to ensure durability and long service life of class 120 polyvinyl acetal enamelled round copper wire.
What’s changed since the last update?
BS EN IEC 60317-18:2020 supersedes BS EN 60317‑18:2004+A1:2010, which is withdrawn.
Some of the changes are:
- Modification of the Scope (Clause 1)
- Revision to the thermal class designation from 105 to 120 in 3.2.2
- Renaming of stretching test to adherence test, and modification to the requirements 8.2
- Revision to the cut-through requirement in Clause 10
