24、The IEC 60811 series specifies the test methods to be used for testing non-metallic materials of all types of cables. These test methods are intended to be referenced in standards for cable construction and for cable materials. NOTE 1 Non-metallic materials are typically used for insulating, sheathi
25、ng, 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 and used for other cables, in particular optical fibr
26、e cables, communication and control cables and cables for ships and offshore applications.

IEC 60811-100:2012, Electric and optical fibre cables Test methods for non-metallic materials Part 100: General 3 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60811-100 a
30、pply. 4 Test method 4.1 General This part of IEC 60811 shall be used in conjunction with IEC 60811-100. For multicore cables and cords, not more than three cores (of different colours, if any) shall be tested, unless otherwise specified in the relevant cable standard. All the tests shall be carried
31、out not less than 16 h after the extrusion or cross-linking, if any, of the compounds used for insulating or sheathing. 4.2 Conditioning procedure A sample of complete cable of sufficient length shall be conditioned in air (i.e. suspended in an oven). The duration of the test and temperature of the
32、air maintained continuously shall be as follows: 7 24 h at (60 2) C for filling compound having a nominal drop point above 50 C and up to and including 70 C; 7 24 h at (70 2) C for filling compound having a nominal drop point above 70 C. BS EN 60811-513:201260811-513 IEC:2012 7 NOTE For an explanati
33、on of the drop point, see IEC 60811-601. After conditioning, the cable sample shall be left at ambient temperature for at least 16 h without being exposed to direct sunlight. The sheath and cores to be tested shall then be taken from the cable and shall be cleaned by suitable means. 4.3 Test procedu
34、re Test pieces according to 4.2 shall be subjected to the following wrapping test: The conductor 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 othe
35、r end of the test piece by means of a winding device on a metal mandrel, preferably mechanically driven, at 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
36、 and shall be kept in their helical form for 24 h at (70 2) C in a vertical position, substantially in the middle of an electrically heated cabinet having natural air flow. For cellular insulations, including foam skin, having a wall thickness below or equal to 0,2 mm, the pull exerted on the expose
37、d conductor shall be reduced to about 7,5 N/mm2 20 % with respect to the conductor cross-section. 4.4 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 on
38、ce only if one test piece fails. 5 Test report The test report shall be in accordance with that given in IEC 60811-100.
