Electric cables. Additional test methods

Alkalmazási terület

1.1 Scope This HD collates and specifies the test methods to be used for testing polymeric insulated and sheathed electric cables, of rated voltage up to and including 20,8/36 kV, intended for public distribution systems, and for use in power generating plants and sub-stations. Test methods in this HD are additional to those already harmonized, e.g. EN 60332-1 series and EN 60811 series, and are used for testing cable types specified in HD 603, HD 604, HD 620, HD 622, HD 626 and HD 627. In each case, these HDs give complementary information needed for the practical application to each specific type. Therefore the present HD as such is not sufficient for carrying out and evaluating the tests on electric cables. Full test conditions (e.g. temperatures, durations) and/or test requirements are not specified in this HD. Such data needed to carry out the tests is given in the particular sections. NOTE The words 'particular section' refer throughout to the section of HD 603 or HD 604, or other HD to which HD 605 applies, in which a particular cable type is specified. 1.2 Applicable tests Tests applicable to each type of cable are given in the particular section, which may also state the sequence, the frequency of test, and the possibility of repeating failed tests. 1.3 Classification of tests The classification of tests is given in Parts 1 of HD 603, HD 604, HD 620, HD 622, HD 626 and HD 627. 1.4 Sampling The size and number of samples are given either in this HD or in the particular HDs. If a marking is indented in the insulation or sheath surface, the samples used for the tests shall be taken so as to include such markings. For multicore cables, except for the test specified in 2.1.1, not more than three cores (of different colours, if available) shall be tested unless otherwise specified. 1.5 Test conditions 1.5.1 Ambient temperature Unless otherwise specified in the details for the particular test, tests shall be made at an ambient temperature of (20 ± 15) °C. 1.5.2 Tolerance on temperature values Unless otherwise specified in the particular specification, the tolerance on temperature values quoted in the test methods are the following: Táblázat 1.5.3 Frequency and waveform of power-frequency test voltages Unless otherwise specified the test voltage shall be in the range 49 Hz to 61 Hz of approximately sine-wave form, the peak ratio value/r.m.s. value being equal to gyökjel2 with a tolerance of ± 7 %. The values given are r.m.s. 1.5.4 Pre-conditioning Unless otherwise stated the tests shall be carried out not less than 16 h after the extrusion or cross-linking, if any, of the insulating or sheathing compounds.
