---Part 9. Resins for cable accessories. The purpose is to determine the terms and definitions, nomenclature, type testing, and supply of resins for cable accessories applications, packaging, logos and labels.

---Part 10. Polyesterimide resin composites. The purpose is to determine the use of electrically heated-UV curable polyesterimide impregnation for electrical insulation technical requirements, test methods, inspection rules and marking, packaging, storage and transportation of resin composites.

1 Scope

This document specifies the technical requirements, inspection rules, markings, and packaging of electrically heated-UV curable polyesterimide resin composites for electrical insulation, packaging, transportation and storage, and the corresponding test methods are described.

This document is applicable to electric heating-UV curing polyesterimide resin composites for motors with heat resistance levels of 180 (H) and 200 (C).

Note: This type of product is composed of heat-resistant unsaturated polyesterimide resin, environmentally friendly reactive cross-linking monomer and composite initiator. Electric heating-UV curing process generally refers to an insulation treatment process in which after being impregnated with insulating resin, the motor stator winding conductors are energized to generate heat and ultraviolet (UV)-assisted curing is used.
