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

31、 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 fundamental and have been developed and used over many years principally for the materials in all energy cables. They have also been wid

32、ely accepted and used for other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore applications.

41、 IEC 60811 shall be used in conjunction with IEC 60811-100. Unless otherwise specified, before any test, all test pieces, aged and unaged, shall be kept for at least 3 h at a temperature of (23 5) C. 4.2 Insulation 4.2.1 General These tests are to determine the tensile strength and elongation at bre

42、ak of the insulating material (exclusive of any semi-conducting layers) of the cable in the condition as manufactured (i.e. without any ageing treatment) and, when required, after one or more accelerated ageing treatment(s), which are prescribed in the relevant cable standard. When the ageing treatm

43、ent is to be carried out on prepared test pieces (in accordance with IEC 60811-401), the test pieces for the ageing treatment shall be from positions adjacent to the test pieces used for the test without ageing and the tensile tests on the aged and unaged test pieces shall be made in immediate succe

44、ssion. NOTE Where further increased test reliability is necessary, it is recommended that the tests on aged and unaged test pieces are performed by the same person using the same testing method and the same apparatus, in the same laboratory. 4.2.2 Sampling One sample of each core to be tested (or of

45、 the insulation from each core to be tested) shall be taken of sufficient size to provide a minimum of five test pieces each for the tensile tests without ageing and the tensile tests after each of the required ageing treatments, bearing in mind that a 100 mm length is needed for the preparation of

46、each test piece. The cores of unsheathed flat cables shall not be separated. Any sample that shows signs of mechanical damage shall not be used for the test. 4.2.3 Preparation and conditioning of test pieces a) Conditioning of test pieces shall be carried out as follows: 1) Elevated temperature cond

47、itioning NOTE 1 Elevated temperature conditioning is not an ageing treatment. It is used as a means of ensuring stable and consistent test pieces when required. It is used a) when called for in the relevant cable standard, or b) if there is a doubt or disagreement about a result and the test needs t

48、o be repeated. In BS EN 60811-501:2012 8 60811-501 IEC:2012 either case, the conditioning applies only to the test piece as taken from the cable before any subsequent treatment (ageing, compatibility test, oil immersion etc). Where conditioning at elevated temperature is used, such conditioning shal

49、l be carried out as follows: for dumb-bells, (A) after the removal of the insulation from the cable and removal of semi-conducting layers (if any) but before the cutting of strips; (B) after grinding (or cutting) to obtain parallel surfaces. Where grinding (or cutting) is not needed, the conditioning shall be performed at the point in the test protocol according to (A); for tubular test pieces, such conditioning shall be carried out after removal
