38、 through the CENELEC and CLC/TC 11 procedures. NOTE The Danish NC also takes sole responsibility for the technically correct coordination of this EN 50341-2-5 with EN 50341-1:2012. It has performed the necessary checks in the frame of quality assurance/control. It is noted however that this quality

39、assurance/control has been made in the framework of the general responsibility of a standards committee under the national laws/regulations. 3 This EN 50341-2-5 is normative in Denmark and informative for other countries. 4 This EN 50341-2-5 has to be read in conjunction with EN 50341-1:2012, herein

40、after referred to as Part 1. All clause numbers used in this Part 2-5 correspond to those of Part 1. Specific sub clauses, which are prefixed “DK”, are to be read as amendments to the relevant text in Part 1. Any necessary clarification regarding the application of Part 2-5 in conjunction with Part

41、1 shall be referred to the Danish NC who will, in cooperation with CLC/TC 11 clarify the requirements. When no reference is made in Part 2-5 to a specific sub clause, then Part 1 applies. 5 In the case of “boxed values” defined in Part 1, amended values (if any) which are defined in Part 2-5 shall b

42、e taken into account in Denmark. However any “boxed values“, whether in Part 1 or Part 2-5, shall not be amended in the direction of greater risk in a Project Specification. 6 The national Danish standards/regulations related to overhead electrical lines exceeding 1 kV (AC) are identified in 2.1/DK1

43、. NOTE All national standards referred to in this Part 2-5 will be replaced by the relevant European Standards as soon as they become available and are declared by the Danish NC to be applicable and thus reported to the secretary of CLC/TC 11.
