19、ETTING RESINS FOR ELECTRICAL PURPOSES Part 3: Specifications for individual materials Sheet 3: Round laminated moulded rods 1 Scope This part of IEC 61212-3 gives requirements for industrial rigid round laminated moulded rods for electrical purposes, based on different resins and different reinforce
20、ments. Applications and 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 pe
21、rformance in that application 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 indispen

26、erties. 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 “4” indicates moulded rods, and, a second digit
27、denoting sub-grades of the same type. The abbreviations are given in 4.3. The complete designation of the moulded rod is denoted by: description: Moulded rod; number of the IEC standard: IEC 6121233; designation of the individual type; dimensions (in millimetres of the moulded rod: diameter x length
28、) a letter designating the finish on the external diameter of the moulded rod: “A“ designating rods in the “as produced“ condition; “B“ designating rods in ground or turned condition.
