This section GB/T 5019 Part 11.

The partial modification of the use of IEC 60371-3-9:1995 "with mica-based insulating materials - Part 3. Specifications for individual materials 9 Articles. plastic mica plate "and the first revision (2007).

This section according to IEC 60371-3-9. (2007 including 1st amendment) redrafted 1995. Taking into account China's national conditions, in the IEC standard Time, made some changes in this section. About the technical differences have been identified in a single vertical line which they are involved with the provisions margin.

This part of IEC 60371-3-9:1995 (including 2007 1st amendment) the differences are as follows.

1) Remove the IEC 60371-3-9:1995 Foreword and Introduction;

2) consider the condition of our country does not use IEC 60371-3-9:1995 Type of product naming;

3) increase the "plasticity" and "Electrical strength" performance requirements;

4) A "inspection rules" chapter.

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 Institute of Electrical Science.

Drafters of this section. Wang Xianfeng.

This section first formulated.

Mica-based insulating materials Part 11. plastic mica plate
