The series consists of three parts: Part 1: Definitions and general requirements (IEC 60464-1); Part 2: Methods of test (IEC 60464-2); Part 3: Spec

26、ifications for individual materials (IEC 60464-3).1 ScopeThis 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 Normati

For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based

28、on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of current
