This section GB/T 1303 Part 1.

This section identical with IEC 60893-1:2004 "thermosetting resins for electrical industrial rigid laminated sheets - Part 1. Definitions, classification and General requirements "(in English).

The technical content section and IEC 60893-1:2004 the same, only delete the reference standard "IEC 60893-4:2003 electrically insulating material Gas thermosetting resins for industrial rigid laminated sheets Part 4. Typical value ", because this part does not use to.

This Part replaces GB/T 18381-2001 "thermosetting resins for electrical industrial rigid laminated sheets definitions, designations and general Claim".

This section differs GB/T 18381-2001 are as follows.

a) identifies the electrical components of thermosetting resins for industrial rigid laminated sheets standard "foreword" in;

b) an increase in Chapter 2, "Normative references";

c) an increase of "5.2 sheet size" clauses.

This part is proposed by the China Electrical Equipment Industrial Association.

This part of the National Standardization Technical Committee of the insulating material (SAC/TC51) centralized.

This part mainly drafted by. Guilin Electrical Apparatus Research Institute, East wood Technology Group Co., Ltd., Beijing Fu Runda new insulation material Limited liability company, Xian Xi, electrical materials limited liability company.
