26、 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, sheathing, bedding, filling or taping within cables. NOTE 2 These test methods are accepted as basic and fundamen
27、tal 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 fibre cables, communication and control cables and cables for ships and offshore applications. BS EN 60811-512

29、C 60811 describes the procedure for testing tensile strength and elongation at break after conditioning at elevated temperature. It is specific to polyethylene and polypropylene compounds. This test is intended for samples from filled cables, of polyolefin insulations with a wall thickness of more t
30、han 0,8 mm and for polyolefin sheaths in direct contact with filling compound. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

33、n with IEC 60811-100. For multicore cables 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 out not less than 16 h after the extrusion or cross-linking, if any, of the compounds used for
34、 insulating or sheathing. BS EN 60811-512:201260811-512 IEC:2012 7 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 air maintained continuously shall be as follows: 7 24
35、 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. NOTE For an explanation of the drop point, see IEC 60811-601. After conditioning, the cable sample shall be left at
36、 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 Tensile strength and elongation tests after conditioning at elevated temperature Tensile strength and/or e
37、longation tests, with respect to requirements in the cable standard, shall be performed on test pieces according to 4.2 in accordance with IEC 60811-501 without any further ageing treatment. 4.4 Expression of results The median of the values of tensile strength and/or elongation at break shall be re
38、corded as the tensile strength and/or elongation at break. 5 Test report The test report shall be in accordance with that given in IEC 60811-100.
