These test methods are

24、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 fundamental and have been developed and use

25、d 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.

27、 and PP compounds, including cellular compounds and foam skin for insulation. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated

29、in polyolefin pipes, fittings and compounds 3 Terms and definitions For the purposes of this document, the terms 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. The assessment shall be carried out in acco

30、rdance with ISO 18553. The method is suitable for use with granules of polyethylene or granule of polypropylene compound or extrusion of polyethylene or polypropylene (for example a sheath). NOTE The method applies with less than 3 % carbon black content. ISO 18553 gives two procedures for the prepa

31、ration of test specimens. Either may be used, but the following recommendations apply: the compression procedure is primarily intended for use with polyethylene compounds, but may be used for extrusions; the microtome procedure is intended for use with polyethylene extrusions. 4.2 Procedure Prepare

33、 of the examination in the manner given in ISO 18553. 4.4 Requirements Unless otherwise stated in the relevant cable standard, the limits recommended in Annex D of ISO 18553:2002 shall be taken to indicate an acceptable degree of dispersion. NOTE Annex D of ISO 18553:2002 states: “The following limi

34、ts are recommended: Grading: mean (see 5.1) 3. Appearance rating: not worse than micrograph B in Annex B (i.e. only dispersion ratings comparable to photomicrographs A1, A2, A3 and B are acceptable).” 5 Test report The test report shall be in accordance with that given in IEC 60811-100.
