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

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

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.
