23、one of a series which deals with industrial rigid round laminated tubes and rods based on thermosetting resins for electrical purposes. This series consists of three parts: Part 1: Definitions, designations and general requirements (IEC 61212-1) Part 2: Methods of test (IEC 61212-2) Part 3: Specific
24、ations for individual materials (IEC 61212-3) IEC 61212-3-1 contains one of the specification sheets comprising Part 3, as follows: Sheet 1: Round laminated rolled tubes.

25、TRICAL PURPOSES Part 3: Specifications for individual materials Sheet 1: Round laminated rolled tubes 1 Scope This part of IEC 61212-3 gives requirements for industrial rigid round laminated rolled tubes for electrical purposes, based on different resins and different reinforcements. Applications an
26、d distinguishing properties are given in Table 1. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that appl
27、ication and not based on this specification alone. Safety warning: It is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner. 2 Normative references The following referenced documents are indispensable for the applicat
28、ion 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.

30、For the purposes of this document, the following modified definition, which is taken from ISO 472, applies. 1To be published EN 61212-3-1:2006 5 3.1 round laminated rolled tube (as applied to thermosets) tube formed by rolling impregnated layers of material on a mandrel between heated pressure rolls
31、, curing in an oven, then removing the mandrel ISO 472 MOD 4 Designations and abbreviations 4.1 General The round laminated rolled tubes covered by this standard are classified into types which differ in the resin and reinforcement used, the method of manufacture and their distinguishing properties.
32、 4.2 Designation Individual types are designated by a two-letter abbreviation denoting the resin; a second two-letter abbreviation, denoting the reinforcement; a serial number of two digits, the first digit denoting the form of the material, a “2” indicates rolled tubes, and, a second digit denoting
33、 sub-grades of the same type. The abbreviations are given in 4.3. The complete designation of the rolled tube is denoted by: description: rolled tube; number of the IEC standard: IEC 6121231; designation of the individual type; dimensions (in millimetres) of the rolled tube: internal diameter x exte
34、rnal (diameter) x length; a letter designating the finish on the external diameter of the rolled tube: “A“ designating tubes in the “as produced“ condition; “B“ designating tubes in ground or turned condition.
