18、ning, supporting and connecting aerial bundled cables (ABC) of rated voltage U0/U (Um): 0,6/1 (1,2) kV. The objective is to provide a method of testing the suitability of accessories when used under normal operating conditions with low voltage aerial bundled cables (ABC) complying with HD 626. There

19、 is variation between the different ABC specifications provided by HD 626, and tests carried out on one of the ABC types may not be completely applicable to ABC of a different specification. Therefore, the purchasers of accessories tested to this European Standard, must ensure that all their require

20、ments are met. NOTE This European Standard does not invalidate existing approvals of products achieved on the basis of national standards and specifications and/or the demonstration of satisfactory service performance. However, products approved according to such national standards or specifications

21、 cannot directly claim approval to this European Standard. It may be possible, subject to agreement between supplier and purchaser, and/or the relevant conformity assessment body, to demonstrate that conformity to the earlier standard can be used to claim conformity to this standard, provided an ass

22、essment is made of any additional type testing that may need to be carried out. Any such additional testing that is part of a sequence of testing cannot be done separately. Climate differs across Europe and in order to meet the differing geographic climatic conditions it is necessary to provide a ra

23、nge of tests to meet these variations. A range of optional, additional tests is provided to meet the varying climatic needs and these should be agreed between the customer and the supplier (see Annex C in EN 50483-6). The purpose of this Part 1 is to define the common aspects of the products include

24、d in the above scope. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
