Foreword

GB/T 5019 "with mica-based insulating materials" is divided into the following sections. --- Part 1. Definitions and general requirements; --- Part 2. Test methods; --- Part 3. Commutator separators and materials; --- Part 4. Mica paper; --- Part 5. electric equipment mica plate; --- Part 6. Polyester film reinforced B stage epoxy resin binder; --- Part 7. vacuum pressure impregnation (VPI) film reinforced with glass cloth and epoxy resin binder; --- Part 8. Glass fabric reinforcement B stage epoxy resin binder; --- Part 9. single wire wrapped with epoxy polyester film mica; --- Part 10. fire-resistant safety cables mica; --- Part 11. plastic mica plate. 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.
