Foreword
GB/T 5019 Insulating Materials based on Mica shall be divided into the following parts.
--- Part 1. Definitions and General Requirements;
--- Part 2. Methods of Test;
--- Part 3. Commutator separators and materials;
--- Part 4. Mica Paper;
--- Part 5. Rigid Mica Materials for heating Equipment;
--- Part 6. Polyester Film-backed Mica Paper with a B-Stage Epoxy Resin Binder;
--- Part 7. Glass-Backed and Film-Backed Mica Paper with an Epoxy Resin Binder
for Vacuum Pressure Impregnation (VPI);
--- Part 8. Glass-Backed Mica Paper with a B-Stage Epoxy Resin Binder;
--- Part 9. Polyester Film Mica Paper with an Epoxy Resin Binder for Single
Conductor Taping;
--- Part 10. Mica Paper Tapes for Flame-Resistant Security Cables;
--- Part 11. Moulding Micanite.
This Part belongs to Part 5 of GB/T 5019.
This Part was drafted as per the rules specified in GB/T 1.1-2009.
This Part replaced GB/T 5022-1998 Rigid Mica Materials for Heating Equipment;
compared with GB/T 5022-1998, this Part has the following differences.
--- The products can be divided into 6 types according to the product applied
different mica substrate and adhesive types. And the required value on
corresponding product thickness and performance are added;
--- Delete “test methods” and “inspection rules”;
--- Add “delivery mode” (see Chapter 8);
--- Change “mark, package, transportation, and storage” into “mark”;
--- Add the appendix A.
This Part adopts re-drafting method to modify and use IEC 60371-3-3.1983
Insulating Materials based on Mica –
Part 5. Rigid Mica Materials for Heating Equipment
