20、ements 1 Scope This part of IEC 60371 gives definitions of terms used to describe built-up mica materials, products based on them and mica paper. It also deals with general requirements and conditions of supply. 2 Normative references The following referenced documents are indispensable for the appl
21、ication of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

23、 the sheet silicates NOTE The two main types used for electrical purposes are a) muscovite (potassium alumino-silicate), b) phlogopite (potassium magnesium alumino-silicate). 3.2 mica splittings laminae split from mica blocks 3.3 mica paper paper-like material consisting entirely of very small flake
24、s of mica without any binder 3.4 built-up mica one or more layers of mica splittings or mica paper bonded together with a suitable binder with or without reinforcement Page4 EN603711:2003 4 Description of material 4.1 Rigid flat mica material or mica paper Built-up mica, bonded under pressure, with
25、or without external heat, in the form of rigid flat pieces. 4.1.1 Rigid material for commutator separators Rigid mica material ground on one or both surfaces. NOTE Commutator separators are the insulation between commutator segments. 4.1.2 Rigid material for heating equipment Rigid mica material cap
26、able of operating at the specified temperature, not usually ground. 4.1.3 Rigid material, heat formable Rigid mica material which can be formed and moulded when heated, not usually ground. 4.2 Flexible mica material Built-up mica usually consists of mica paper with a suitable binder with or without
27、reinforcement which is sufficiently flexible to permit winding or wrapping into place, with or without heat. The flexibility may or may not be maintained after application. 4.2.1 Flexible mica material impregnated with B stage resin FlexibIe mica material with a binder suitable for final cure after
28、application. 4.2.2 Flexible mica material, porous for post-impregnation Flexible mica material containing a small amount of binder used in conjunction with vacuum pressure impregnation (VPI) with compatible impregnants. 4.2.3 Flexible mica material for fire security cables Flexible mica material wit
29、h a suitable binder designed for use in cables capable of operating after fire. 5 General requirements and conditions of supply See the appropriate sheets of IEC 60371-3. _ Page5 EN603711:2003 Annex ZA (normative) Normative references to international publications with their corresponding European p
