23、811-502:201260811-502 IEC:2012 5 INTRODUCTION 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 materi

24、als 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 and use

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

28、and 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. 4.2 Test equipment The test equipment shall be as follows: an air oven, electrically heated, capable of maintaining the test temperature; a measuring device

29、 with a scale division of 0,5 mm. 4.3 Sampling One sample about 1,5 L mm in length of each core to be tested shall be taken at least 0,5 m away from the end of the cable length. L is the length given in the relevant cable standard. 4.4 Preparation of test pieces All coverings, except adherent, extru

30、ded semi-conducting screens, if any, shall be removed from the samples of insulated conductor. Within an interval of not more than 5 min from the time of cutting the samples, a test length of L 5 mm shall be marked on the middle part of each piece of core. The distance between the marks shall be mea

31、sured to an accuracy of 0,5 mm. Each test piece shall then be BS EN 60811-502:201260811-502 IEC:2012 7 prepared by cutting and removing the insulation from both ends of each sample up to positions between 2 mm and 5 mm away from the marks. 4.5 Test procedure Each test piece shall be supported horizo

32、ntally in the air oven preheated to the temperature specified in the cable standard by the bare ends of conductors or on the surface of a preheated talc bath, to permit free movement of the insulation. Each test piece should remain in the oven for the time specified in the cable standard. Each test

33、piece shall then be removed from the oven and allowed to cool in air to room temperature and the distance between the two marks on each piece measured again to the nearest 0,5 mm. 4.6 Expression of results The percentage shrinkage L is the difference between the distances between the marks before th

34、e heat treatment (L1) and after the heating and cooling (L2), recorded as a percentage of the distance between the marks before the treatment: L = %100121LLL5 Test report The test report shall be in accordance with that given in IEC 60811-100.
