These test methods are intended to be referenced in standards for cable construction and for cable materials. NOTE 1 Non-metallic m

25、aterials are typically used for insulating, sheathing, bedding, filling or taping within cables. NOTE 2 These test methods are accepted as basic and fundamental and have been developed and used over many years principally for the materials in all energy cables. They have also been widely accepted an

26、d used for other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore applications.

27、c to polyethylene and polypropylene compounds Wrapping test after thermal ageing in air 1 Scope This Part 510 of IEC 60811 specifies the test method for a wrapping test after thermal ageing in air. This test method applies specifically to polyolefin insulation in communication cables. This test is i

28、ntended for polyolefin insulations of unfilled cables and of dry cores for filled cables, where the insulation has a wall thickness of less than or equal to 0,8 mm. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable

29、for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60811-100:2012, Electric and optical fibre cables Test methods for non-metallic materials Part 100: General 3 Terms

30、 and definitions For the purposes of this document, the definitions given in IEC 60811-100 apply. 4 Test method 4.1 General This part of IEC 60811 shall be used in conjunction with IEC 60811-100. All the tests shall be carried out not less than 16 h after the extrusion or cross-linking, if any, of t

31、he compounds used for insulating or sheathing. 4.2 Apparatus The apparatus consists of the following parts: a smooth metal mandrel and loading elements; a winding device, preferably with mechanically driven mandrel; an electrically heated cabinet with natural air flow. 4.3 Sampling The test shall be

32、 carried out on four test pieces for each length of cable or core to be tested. Take a sample 2 m long and cut it into four test pieces of equal length. BS EN 60811-510:201260811-510 IEC:2012 7 Carefully remove the coverings and braidings, if any, from the test pieces and any filling compound which

33、may adhere to the cores. Leave the conductor within the insulation. Then straighten the test pieces. 4.4 Ageing procedure The test pieces prepared in accordance with 4.3 shall be suspended vertically for 14 24 h at (100 2) C in the middle of the heating chamber in accordance with 4.2 so that each te

34、st piece is at least 20 mm from any other test piece. Not more than 2 % of the chamber volume shall be occupied by the test pieces. Immediately after the ageing period, the test pieces shall be taken out of the chamber and left at ambient temperature, without being exposed to direct sunlight, for at

35、 least 16 h. NOTE The ageing time and/or ageing temperature may be increased if required by the relevant cable specifications. 4.5 Test procedure 4.5.1 Test pieces according to 4.3 shall be subjected, after ageing in accordance with 4.4, to a winding test at ambient temperature. 4.5.2 The conductor

36、shall be laid bare at one end. A weight shall be applied to the exposed conductor end, exerting a pull of 15 N/mm2 20 % with respect to the conductor cross-section. Ten windings shall be made on the other end of the test piece by means of a winding device in accordance with 4.2 on a metal mandrel at

37、 a speed of about 1 revolution per 5 s. The winding diameter shall be 1 to 1,5 times the test piece diameter. Subsequently, the test pieces wound on the mandrel shall be removed from the latter and shall be kept in their helical form for 24 h at (70 2) C in the vertical position, substantially in th

38、e middle of the heating chamber in accordance with 4.2. 4.6 Evaluation of results After cooling down to ambient temperature, the test pieces shall show no cracks when examined with normal or corrected vision without magnification. The test may be repeated once more if a test piece fails. 5 Test repo

39、rt The test report shall be in accordance with that given in IEC 60811-100.
