This section GB/T 5019 Part 8.

The partial modification of the use of IEC 60371-3-6:1992 "with mica-based insulating materials - Part 3. Specifications for individual materials 6 Articles. Glass fabric reinforcement B stage epoxy resin binder "and the first Amendment (2006) (in English).

This section according to IEC 60371-3-6:1992 and the first redrafting Amendment (2006). Taking into account China's national conditions, in use IEC 60371-3-6:1992 and the first Amendment (2006), this part has made several modifications. About the technical differences between them involved Terms of the margin identified by a single vertical line.

This part of IEC 60371-3-6:1992 and the first Amendment (2006) The differences are as follows.

1) Remove IEC 60371-3-6:1992 Foreword;

2) consider the condition of our country does not use IEC 60371-3-6:1992 Type of product naming;

3) the length of its diameter bonded mica tape volumes and disk representation (IEC 60371-3-6 to tape length indication);

4) increase the "edge curvature", "gel time", "softness", "electric strength (uncured)" performance requirements;

5) A "inspection rules" chapter;

6) increase of the applicable content and storage conditions.

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 section is drafted. Sichuan East wood Technology Group Co., Xi'an Electric Electrical Materials Co., Ltd., Harbin celebrate edge Electrical Materials Co., Ltd., National Engineering Research Center of insulating material, Guilin Institute of Electrical Science.
