10、combined with the corresponding Part from HD 622 (Power cables having rated voltage from 3.6/6(7.2)kV up to and including 20.8/36(42)kV with special fire performance for use in power stations) to form Amendment No. 1 to HD 605. Each of Parts 3-9 inclusive are further divided into particular sections
11、 and, by decision of the Technical Board (D68/047) National Committees need at present only implement in their national language those sections having national applicability. The obligation remains however to announce the full HD in public by titles and numbers, and also to withdraw any conflicting
12、national standards. Page numbering reflects the arrangement into Parts and particular sections, e.g. Page 442-3 is page 3 of particular section C of Part 4. References to other HDs, ENS and international standards are given in the particular parts or sections. The draft was submitted to the formal v
13、ote and was approved by CENELEC as HD 620 S1 on 1995-1 1-28.

This Part (Part 1) specifies the general requirements applicable to these cables, unless otherwise specified in the particular sections of this HD.
39、 Test methods specified are given in EN 6081 1, HD 383, HD 405, HD 605 and in IEC Publications 229, 840, 885-2 and 885-3. 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 conside
40、red 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 m
41、ore experience should be gained before starting to rationalise this important matter. The particular types of cables are specified in Parts 3 to 9. 1.2 Object The objects of this Harmonisation Document are: - to standardise cables that are safe and reliable when properly used, in relation to the tec
42、hnical requirements of the system of which they form a part; - to state the characteristics and manufacturing requirements which have a direct or indirect bearing on safety; - and to specify methods for checking conformity with those requirements. 2.
