24、 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 materials are typically used for insulating, sheathing, bedding, filling or taping within cables. NOTE 2 These
25、 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 used for other cables, in particular optical fibre cables, communication and control cables and cables for
26、 ships and offshore applications.
