适用范围：1.1 This standard ( Part 1 ) covers the requirements and tests for circular, elastomer insulated, overall braided or elastomer sheathed lift cables of rated voltage up to and including 1 100 V.1.2 These cables are suitable for use, where the combination of ambient temperature and temperature rise due to load, results in a steady conductor temperature not exceeding 60°C.1.3 Cables covered in this standard are intended for installations where the freely-suspended length does not exceed 35 m, and the speed of travel does not exceed 1·6 m/s. The requirements for cables outside these limits is a matter of negotiation between the purchaser and the manufacturer.1.4 The cables covered in this standard may be used for similar applications requiring flexible connections.
