HD 620 applies to cables with extruded insulation and for rated voltages Uo/U(Um) from 3,6/6 (7,2) kV up to 20,8/36(42) kV used in power distribution systems of voltages not exceeding the maximum r.m.s. value of the system voltage Um. This Part (Part 1) specifies the general requirements applicable to these cables, unless otherwise specified in the particular sections of this HD. Test methods specified are given EN 60228, EN 60229, EN 60332-1-2, EN 60811, EN 60885-3, HD 605 and HD 632. Attention should be drawn to the fact that a significant number of sections include references to long term tests which are collected in HD 605. These long-term tests are considered as necessary and reflect the best available knowledge for the existing cable design. They are related to specific designs and different philosophies concerning adequate measures against the influence of water. However, it is the firm intention to reduce this large number of different tests, but more experience should be gained before starting to rationalise this important matter. The particular types of cables are specified in Parts 9 to 12. NOTE Parts 3, 4, 5, 6, 7 and 8 were withdrawn in HD 620 S2.

EN 50306-1 specifies the general requirements applicable to the cables given in EN 50306-2, EN 50306-3 and EN 50306-4. It includes the detailed requirements for S2 sheathing materials and other components called up in the separate parts. NOTE Detailed requirements for insulation systems are given in EN 50306-2. In particular, EN 50306-1 specifies those requirements relating to fire safety which enable the cables to satisfy Hazard Level 3 of EN 45545-1 and EN 45545-2. These cables are rated for occasional thermal stresses which causes ageing equivalent to continuous operational life at a temperature of 105 °C or 90 °C. For standard cables, this is determined by the acceptance test defined in EN 50305, using accelerated long-term (5 000 h) thermal ageing indicating a 125 °C or 110 °C /20 000 h temperature index. If the customer were to require lifetime predictions, this would be demonstrated based on the temperature index of the product as supplied by the manufacturer. The maximum temperature for short circuit conditions is 160 °C based on duration of 5 s. EN 50306-1 is expected to be used in conjunction with one or more of the other parts of EN 50306.

This document describes the procedure and rules for extended application of results of tests carried out according to the test methods described in EN 50399, EN 60332 1 2 and EN 61034 2. The EXAP rules described apply to EN 50399 test results used for classification according to EN 13501 6 in classes B2ca, Cca and Dca, additional smoke production classes s1, s2 and s3 and flaming droplets/particles, to EN 60332 1 2 test results used for classification in classes B2ca, Cca, Dca and Eca and to EN 61034 2 test results used for classification in classes s1a and s1b. No EXAP procedure and rules have been developed in respect to the results of tests carried out according to the test method described in EN 60754 2. As the parameters (pH and conductivity) for each cable in a family are determined based upon calculation using material test results, this is considered as a matter of direct application. Material test results taken from any one sample of finished cable from a family are sufficient to calculate the parameters for each cable in the family. Cables with a diameter of 5,0 mm or less are expected to be tested as bundles according to EN 50399. Cables with a diameter of less than or equal to 5,0 mm are included in the specific and general EXAP rules for single core unsheathed power cables only. The rules apply to circular and non-circular cables provided that they fall within the scope of the relevant test method. A specific EXAP rule has been developed for any of the types of electric cable families as defined in this document. A general EXAP rule has been developed for all electric cable families unless otherwise stated elsewhere in this document. NOTE 1 Multicore power cables are sometimes referred to as control cables with a rated voltage but for the purposes of this document are considered as power cables. For multipair, multitriple and multiquad control cables, either the general EXAP rule or the specific EXAP rule for power cables or the specific EXAP rule for communication cables can be applied. The use of the specific EXAP rule gives benefit in the lower number of cables to be tested for a range of cable constructions (product family). An EXAP is only possible when cables belong to a family as defined in this document. NOTE 2 For the purposes of this document, the term "electric cables" also covers optical fibre cables.

This document EN 60331-1 specifies the test method for cables which are required to maintain circuit integrity when subject to fire and mechanical shock under specified conditions. This document is applicable to cables of rated voltage not exceeding 600 V/1 000 V, including those of rated voltage below 80 V, metallic data and telecom cables and optical fibre cables. It is intended for use when testing cables of greater than 20 mm overall diameter. Although the scope is restricted to cables with rated voltage up to and including 0,6/1,0 kV, the procedure can be used, with the agreement of the manufacturer and the purchaser, for cables with rated voltage up to and including 1,8/3 (3,3) kV, provided that suitable fuses are used.

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.

IEC 60230:2018 defines the procedure for carrying out withstand lightning and switching impulse tests and withstand superimposed impulse test on cables and their accessories. This document applies solely to the methods of carrying out the tests as such, independently of the problem of selecting the test levels to be specified. The voltages pertaining to the system on which cables and accessories are to be used are given in IEC 60183 or in the relevant product standard. This document specifies the following requirements: - the characteristics and state of the test installation and those parts of the procedure which are common to withstand tests and tests above the withstand level; - the procedure for carrying out withstand lightning, switching impulse tests and superimposed impulse test; - the procedure for carrying out tests above the withstand level which is intended for research purposes. This second edition cancels and replaces the first edition published in 1966. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the structure of the standard takes into account the current style of IEC standards; b) this document is no longer a “Recommendation” but an “International Standard”; c) the test installation is no longer related to gas-pressure and oil-filled cables only; d) switching-impulse voltage and superimposed impulse voltage tests have been included; e) for the measuring system the reference to IEC 60060-2 has been added. The reference to the sphere gap method has been moved to Annex B.
