| 7 | Introduction This International Standard is one of a series which deals with varnishes used for electrical insulation. The series consists of three parts: 1 Scope This part of IEC 60464 relates to varnishes used for electrical insulation. !Text deleted ” The varnishes may be used for finishing or impregnating applications, and may be dried or dried and cured at ambient or elevated temperatures. 2 Normative references The following normative documents contain provisions which, through reference in the text, constitute provisions of this Interna… IEC 60464-3-1, Varnishes used for electrical insulation – Part 3: Specifications for individual materials – Sheet 1: Ambient curing finishing varnishes. IEC 60464-3-2, Varnishes used for electrical insulation – Part 3: Specifications for individual materials – Sheet 2: Hot curing impregnating varnishes1). ISO 472:1988, Plastics – Vocabulary. ISO 1043-1:1997, Plastics – Symbols and abbreviated terms – Part 1: Basic polymers and their characteristics. 3 Designation The commonly used applications are as shown in Table 1. Table 1 – Application methods The code letters associated with the application may be used as an abbreviation of the application description. Further applications and associated code letters may be added if so required. Depending on their composition and purpose, these varnishes dry or dry and cure at ambient or at elevated temperature. The desig… Table 2 – Basic resins !The designation letter of the varnish type shall follow the resin type letter in brackets. Table 3 – Varnish types Type Code letter ” The code letters associated with the designation may be used as abbreviation of the polymer description.
