4、- 2 60371-3-4 Amend. 1 IEC:2006(E) FOREWORD This amendment has been prepared by IEC technical committee 15: Standards on specifications for electrical insulating materials. The text of this amendment is based on the following documents: FDIS Report on voting 15/332/FDIS 15/347/RVD Full information o
5、n the voting for the approval of this amendment can be found in the report on voting indicated in the above table. The committee has decided that the contents of this amendment and the base publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:
6、/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. _ Page 7 INTRODUCTION Replace the existing text by the following new text: This International Standard is one of a series which
7、deals with insulating materials for use in electrical equipment built up from mica splittings or mica paper, with or without reinforcement, and with mica paper in its pure state. The series consists of the following three parts: Part 1: Definitions and general requirements (IEC 60371-1) Part 2: Meth
8、ods of test (IEC 60371-2) Part 3: Specifications for individual materials (IEC 60371-3) This standard contains one of the sheets comprising part 3, as follows: Sheet 4: Polyester film-backed mica paper with a B-stage epoxy resin binder.

10、phs: Materials which conform to this specification meet established levels of performance. However, the selection of materials by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification al

13、 plastic films for electrical purposes Part 3: Specifications for individual materials Sheet 2: Requirements for balanced biaxially oriented polyethylene terephthalate (PET) films used for electrical insulation 3 Designation Replace the existing first two paragraphs by the following new paragraphs:
14、When ordering materials to this specification, only the specification and type numbers need be quoted (see Table 1). Example: IEC 60371-3-4: type 4.1.01 The type number is derived from: the specification sheet number 4 followed by the sheet table number 1 followed by the number of the product in the
15、 sheet table 01 Thus giving type number 4.1.01. The final paragraph and table remain unchanged.
