25、c range of the measuring equipment to yield the required level of accuracy. The length should be measured with an accuracy better than 1 % unless otherwise stated in the relevant cable specification. 4.2 Pre-conditioning The CUT shall be pre-conditioned at a constant ambient temperature for such tim
26、e as to allow the specimen temperature to stabilize according to 6.1. 5 Tests The tests required and performance characteristics applicable to each type of cable are given in the relevant cable standard. 6 Test conditions 6.1 Ambient temperature Tests shall be made at an ambient temperature within t
27、he range 15 C to 35 C unless otherwise specified. 6.2 Tolerance on temperature values Unless otherwise specified in the relevant specification, the tolerance on temperature shall be 2 C. 7 Equipment calibration 7.1 Calibration Equipment calibration shall be considered part of the quality system. 8 T
