Scope
Introduction This amendment to EN 50620:2017 is needed to clarify and correct the wording of EN 50620 and to amend Annex ZZ@ giving the relationship of the requirements of the Low Voltage Directive (2014/35/EU) to the content of EN 50620. a) The Scope has to be clearly defined@ giving precise limits of the product. Under item b) of the Scope it is stated that cord sets are included. The wording has been modified to show that all kinds of accessories and plugs are excluded from the scope of this standard. b) The Introduction is not present in EN 50620@ it is not clear why the standard is needed. The amendment covers the history from the Vilamoura notification from Germany and response from CLC TC20 to cover the project on European level@ based on the need for a specific cable for power supply to electric vehicles. c) The identification of the Legislation and Standardization Request has to be clear and unambiguous. The ??European foreword?? of EN 50620:2016 has been amended to mention the LVD and mandate M/511. d) The sizes of the CC/CP cores in 6.2 have to be corrected to cover the range from 0@5 mm? to 1@0 mm?. e) All relevant (significant) essential or other legal requirements have been identified (under consideration of possible limitations in the scope)@ e.g. significant hazards. See Annex ZZ. f) Where appropriate@ for the identified relevant (significant) requirements@ appropriate and verifiable measures for reduction of uncertainty or risk have been specified (as far as possible performance based). See Annex ZZ. g) The requirements have to be compatible with good safety engineering practice@ state of the art safety expertise or appropriate reference standards. A remark about sampling requirements for the sample test have been added@ explaining that no rule on frequency is possible for this special product@ therefore this item will be subject to the contract parties / as requested by the customer. Sample Tests should be carried out on samples taken according to quality control procedures agreed between manufacturer and purchaser. Measurement uncertainties/tolerances are given in the test method standards. Yes o covering the pass/fail criterion need no uncertainty@ limit values do not need uncertainty ranges. h) The terms and definitions correspond to the terms and definitions appropriate to cable standards in IEC and CLC. ??Type test?? definition from electropedia is based on a different product@ therefore no modification will be introduced. Any deviation in these generic definitions are not able to be in conflict to the essential requirements in the LVD
