1 General 1.1 Scope This part of GB/T 2951 specifies the test methods to be used for testing polymeric insulating and sheathing materials of electric and optical fibre cables for power distribution and telecommunications, including cables used on ships and in offshore applications. These test methods apply specifically to polyolefin insulation and sheath. 1.2 Normative References The following normative document contains provisions which, through reference in this text, constitute provisions of this part of GB/T 2951. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document referred to applies. ?
