This section GB/T 5019 Part 2.

The partial modification using IEC 60371-2:2004 "with mica-based insulating materials - Part 2. Test methods" (in English).

This section according to IEC 60371-2:2004 redrafted. This section lists the reg number and IEC 60371-2 in Appendix A.

2004 reg control list numbered.

Taking into account China's national conditions, in using IEC 60371-2:2004 when this part has made several modifications. These techniques are listed in Appendix B List surgery differences and the reasons for the reference.

This section instead of 5019-2002 "Test Method for insulating materials based on mica" GB/T .

This part of GB/T 5019-2002 compared to the main changes are as follows. increasing the "heating reduction", "softness", "edge curvature" "From the floor rate", "plasticity", "volume resistivity", "high-temperature insulation resistance." this section of the Appendix A, Appendix B are informative appendices.

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. Guilin Institute of Electrical Science.
