The document rationalises all those test methods which are additional to those in HD 405 and HD 505, and which were originally planned to be included in Part 2 of each of HD 603 (Distribution cables of rated voltage 0.6/1kV) and HD 604 (0.6/1kV Power Cables with special fire performance for use in power stations). Consequently there is no Part 2 for either HD 603 or HD 604. By decision of the Technical Board (D68/047) National Committees are only required to implement in their national language the nationally applicable parts of HD 603 and HD 604. Therefore not all test methods in HD 605 apply to both the other HDs, nor are they all called up by any particular nationally applicable part. The draft was submitted to the CENELEC members for formal vote in March 1993 and was approved by CENELEC as HD 605 S1 on 8th December 1993. References to other HDs, ENS and international standards are given in Annex 111.

Unless otherwise specified one sample of cable shall be taken from each of three places. Compliance shall be checked on each core of cables having up to five cores, and on the number of cores stated in the individual specification for cables with more than five cores. If withdrawal of the conductor is difficult, it shall be stretched in a tensile machine or the piece of core shall be immersed in an appropriate liquid until the insulation becomes loose. 2 . 1 .1.2 Evaluation of results Unless otherwise specified the mean of the 18 values (expressed in millimetres) obtained from the three pieces of insulation from each core shall be calculated to two decimal places and rounded off as given below, and this shall be taken as the mean value of the thickness of insulation. If in the calculation the second decimal figure is 5 or more, the first decimal figure shall be raised to the next number thus, for example, 1.74 shall be rounded off to 1.7 and 1.75 to 1.8. The lowest of all values obtained shall be taken as the minimum thickness of insulation at any place. 2.1.2 Measurement of non-metallic sheath thickness 2.1.2.1 Procedure The thickness of sheath shall be measured in accordance with sub-clause 8.2 of HD 505.1.1. Unless otherwise specified one sample of cable shall be taken from each of three places. 2.1.2.2 Evaluation of results The mean of all the values (expressed in millimetres) obtained from the three pieces of sheath shall be calculated to two decimal places and rounded off as given below, and this shall be taken as the mean value of the thickness o f the sheath. If in the calculation the second decimal figure is 5 or more, the first decimal figure shall be raised to the next number, thus, for example, 1
