A centre core is not permitted. A protective conductor, if any, shall be applied in the outer layer. A centre filler may be used

34、, and is however compulsory for cables having 6, 18, and 36 cores, and also for 7 and 19 cores when these non-preferred sizes are used. The centre filler shall consist of a suitable material. A tape of suitable material may be applied around the core assembly before application of the sheath. 6.3.6

35、Sheath The core assembly shall be covered with a sheath. The sheath shall be applied either in a single layer, rubber compound EM2, or in two layers, with the inner layer made of either rubber compound EM1 or EM3 and the outer layer of rubber compound EM2. The application of a tape between the two l

36、ayers is optional. The thickness of sheath shall comply with the specified value given in part 4 Table IX columns 3, 4 and 5. The sheath in a single layer or the inner layer of the sheath in two layers shall fill the spaces between the cores. The sheath shall be capable of being removed, without dam

The lower limit given in Part 4, Table IX, Column 6 shall be regarded as an indicative value only and not a requirement for compliance with this specification. 6.3.8

38、 Outer markinas At least the designatory marking RN shall be printed or embossed on, or indented into, the polychloroprene sheath. The marking shall be continuous, in accordance with Part 1 , sub-clause 3.1.1 I 6.4 Tests Compliance with the requirements of Part 4, Sub-clause 6.3 shall be checked by
