適用范圍：1.1 This standard covers the requirements and tests for the following types of unarmoured polyethylene (PE) insulated, PVC or PE sheathed cables with copper or aluminium conductors for electric power and lighting (including weatherproof cables) for voltages up to and including 1 100 V.Note — For use as weatherproof cables, the sheath of PE sheathed cables shall have a suitably dispersed carbon black content (see 5.2.1 ; and the PVC sheathed cables shall meet the requirements of additional ageing test [see 11.1 (m) and 11.2 (h)].1.1.1 Types of Cablesa) Single core;b) Circular twin, three and four core;c) Flat twin with or without ECC; andd) Flat three core.1.2 The cables covered in this standard are suitable for use on ac single phase or three phase (earthed or unearthed) system for rated voltages up to and including 1 100 V. These cables may be used on dc systems for rated voltages up to and including 1 500 V.1.3 The cables covered by this standard are suitable for use where the combination of ambient temperature and temperature rise due to load results in continuous conductor temperature not exceeding 70°C.
