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 fundamental an

25、d 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.

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 apply. 4 Test

29、 method 4.1 General This part of IEC 60811 shall be used in conjunction with IEC 60811-100. This test is used to examine the possible interaction between insulation materials and filling compounds of filled cables. It is intended only for the purpose of material selection. 4.2 Apparatus For the purp

30、ose of this test, the different equipment used is as follows: a) a glass vessel; b) an oven with natural air flow; c) an analytical balance with a precision of 0,1 mg. 4.3 Sampling and test pieces preparation Three samples of each colour of insulated core shall be taken from a cable before the filli

31、ng process. Each sample of about 2 m shall be cut into three pieces of length 600 mm, 800 mm and 600 mm. BS EN 60811-407:201260811-407 IEC:2012 7 4.4 Test procedure The 800 mm test piece shall be immersed in about 200 g of filling compound contained in a glass vessel and pre-heated to the following

32、temperature: (60 2) C for filling compound having a drop-point above 50 C and up to and including 70 C; (70 2) C for filling compound having a drop-point above 70 C. NOTE For an explanation of the drop-point, see IEC 60811-601. At least 500 mm of the middle part of this test piece shall be immersed

33、in the compound without contact with the glass vessel or another specimen. The ends of the test piece shall be kept out of the compound. The glass vessel shall be stored for 10 24 h in an oven and the temperature shall be maintained continuously at the value specified above for the relevant filling

34、compound. At the end of the period, the test piece shall be removed from the filling compound and carefully cleaned with absorbent paper. The ends of the test piece shall then be cut away leaving at least 500 mm of the middle part that has been immersed in the filling compound. The two dry 600 mm pi

35、eces shall be cut back to the same length as the immersed test piece and the conductor shall be removed from all three. 4.5 Measurements The three test pieces shall be weighed at ambient temperature to the nearest 0,5 mg. 4.6 Expression of the result The mass increase W, expressed in per cent, shall

36、 be determined as follows: 100112=MMMW where M1is the mean mass of the two dry test pieces; M2is the mass of test piece immersed in the filling compound. 5 Test report The test report shall be in accordance with that given in IEC 60811-100.
