27、 Specifications for individual materials Sheet 2: Round laminated moulded tubes 1 Scope This part of IEC 61212 gives requirements for industrial rigid round laminated moulded tubes for electrical purposes, based on different resins and different reinforcements. Applications and distinguishing proper
28、ties 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 application and not based o
29、n 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 documents, in whole or in part, are normatively referenced in this document an

34、assified into types which differ in the resin and reinforcement used, the method of manufacture and their distinguishing properties. 4.2 Designation Individual types are designated by: a two-letter abbreviation denoting the resin; a second two-letter abbreviation, denoting the reinforcement; a seria
35、l number of two digits, the first digit denoting the form of the material, a “3” indicates moulded tubes, and, a second digit denoting sub-grades of the same type. The abbreviations are given in 4.3. The complete designation of the moulded tube is denoted by: description: moulded tube; number of the
36、 IEC standard: IEC 61212-3-2; designation of the individual type; dimensions (in millimetres) of the moulded tube: internal diameter external diameter length; a letter designating the finish on the external diameter of the moulded tube: “A“ designating moulded tubes in the “as produced“ condition; “
37、B“ designating moulded tubes in ground or turned condition.
