36、temperature close to water freezing point for a fixed time 3.2 type tests tests made on materials or components of a cable accessory in order to demonstrate satisfactory performance characteristics to meet the intended application 3.3 outer protection cured resinous compound to protect the connectio

37、ns from damage by external mechanical forces 4 Designation Resins for cable accessories are classified according to their application in categories as follows: Table 1 Categories of resins Voltage Class Function Characteristic Low Voltage (L) Outer Protection (OP) Cures in presence of water a(W) Med

38、ium Voltage (M) Insulation (I) a Low foaming during curing when in contact with water as described in the subclause dealing with curing under water in IEC 60455-2. A resin is identified by a combination of categories. For example: Low voltage compound for outer protection: L-OP; Low voltage compound

39、 for insulation, curing in presence of water: L-I-W; Low voltage compound for insulation and mechanical protection: L-OP-I. Tests for type testing are carried out in accordance with each of the resin categories. Low voltage: 0,6/1,0 (1,2) kV Medium voltage: 20,8/36 (42) kV 5 Type testing 5.1 General

40、 Tests shall be carried out based on the category of the resins as defined in Table 1. These tests are of such a nature that, once successfully completed, they need not to be repeated unless changes are made in the material, component formulation or manufacturing process, which might change the perf

The type testing of resins shall be carried out either: as a stand-alone test. Samples used for the type test

42、shall be taken from material available as agreed between supplier and user. or in combination with an accessory type test. Samples used for the resins type test shall be taken from the same batch as used in the accessory type test. In the event that no material from the same batch is available, then

43、 the samples used for the resins type test shall be taken from material available as agreed between supplier and user. 5.3 Preparation and conditioning 5.3.1 General For all tests, unless otherwise specified, conditioning shall be made in accordance with IEC 60212 using standard atmosphere B. 5.3.2

44、Individual components prior to mixing Components (resin and reactive component) shall be individually prepared, conditioned and tested in accordance with the relevant test method as specified in stage 1 of the sequence of tests given in Table 2. Filler, when supplied as a separate item, shall not be
