This series consist of three parts: Part 1: Definitions and general requirem
27、ents (IEC 60455-1); Part 2: Methods of test (IEC 60455-2); Part 3: Specifications for individual materials (IEC 60455-3) IEC 60455-3-8 consists of one of the sheets comprising Part 3 as follows: Sheet 8: Resins for cable accessories BS EN 60455-3-8:2013 6 60455-3-8 IEC:2013 RESIN BASED REACTIVE COMP

35、Liquid epoxy resins Determination of tendency to crystallize 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 tendency to crystallization measurement of the ability of epoxy base resin not to change from a liquid to a solid state at a certain
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
41、ormance characteristics. BS EN 60455-3-8:2013 8 60455-3-8 IEC:2013 5.2 Sampling Samples for type testing shall be taken from material stored under conditions prescribed by the manufacturer. 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
45、 tested as a component. 5.3.3 Resin just after mixing (curing stage) Compounds shall be prepared and mixed according to suppliers instructions and tested as specified in stage 2 of the sequence of tests specified in Table 2. 5.3.4 Cured resin (original) Compounds shall be prepared according to suppl
46、iers instructions and cured for 24 h at room temperature unless otherwise specified in the test method referred to in stage 3 of the sequence of tests given in Table 2. The specimens shall be post-cured at (80 2) C for 24 h unless otherwise specified in the test method, and then cooled in a desiccat
47、or for 24 h at room temperature. NOTE If degassing is needed, it will be indicated in the relevant test method and the conditions for the degassing will also be indicated. 5.3.5 Cured resin after thermal ageing (dry and wet) Cured resin shall be prepared according to suppliers instructions and cured
48、 for 24 h at room temperature unless otherwise specified in the test method referred to in stage 4 of the sequence of tests given in Table 2. The specimens shall be post-cured at (80 2) C for 24 h unless otherwise specified in the test method, and then cooled in a desiccator for 24 h at room tempera
49、ture. NOTE If degassing is needed, it will be indicated in the relevant test method and the conditions for the degassing will also be indicated. 5.4 Sequence of tests Tests shall be carried out on the resin in the following four stages, in accordance with Table 2: Stage 1: Reactive components prior to mixing; Stage 2: Resin just after mixing; Stage 3: Cured resin (original); BS EN 60455-3-8:201360455-3-8 IEC:2013 9 Stage 4: Cured resin after heat exposure (
