44、 The Norwegian NC has prepared this Part 2-16 of EN 50341-1:2012, listing the Norwegian national normative aspects, under its sole responsibility, and duly passed it through the CENELEC and CLC/TC 11 procedures. NOTE The Norwegian NC also takes sole responsibility for the technically correct coordin

45、ation of this EN 50341-2-16 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 assurance/control has been made in the framework of the general responsibility of a standards committee under the national laws/reg

46、ulations. 3 This EN 50341-2-16 is normative in Norway and informative for other countries. 4 This EN 50341-2-16 has to be read in conjunction with EN 50341-1:2012, hereinafter referred to as Part 1. All clause numbers used in this Part 2-16 correspond to those of Part 1. Specific subclauses, which a

47、re prefixed “NO”, are to be read as amendments to the relevant text in Part 1. Any necessary clarification regarding the application of Part 2-16 in conjunction with Part 1 shall be referred to the Norwegian NC who will, in cooperation with CLC/TC 11 clarify the requirements. When no reference is ma

48、de in Part 2-16 to a specific subclause, then Part 1 applies. 5 In the case of “boxed values” defined in Part 1, amended values (if any) which are defined in Part 2-16 shall be taken into account in Norway. However any “boxed values“, whether in Part 1 or Part 2-16, shall not be amended in the direction of greater risk in a Project Specification. 6 The national Norwegian standards/regulations related to overhead electrical lines exceeding 1 kV (AC) are identified in 2.1/NO1. NOTE All national standards referred to in this Part 2-16 will be replaced
