The difference
35、 type is noted on the rst line of the National Difference in the standard. The standard may not include all types of these National Differences. DR These are National Differences based on the national regulatory requirements. D1 These are National Differences which are based on basic safety principl
36、es and requirements, elimination of which would compromise safety for consumers and users of products. D2 These are national differences from IEC requirements based on existing safety practices. These requirements reect national safety practices, where empirical substantiation (for the IEC or nation
37、al requirement) is not available or the text has not been included in the IEC standard. DC These are National Differences based on the component standards and will not be deleted until a particular component standard is harmonized with the IEC component standard. DE These are National Differences ba
38、sed on editorial comments or corrections. Each national difference contains a description of what the national difference entails. Typically one of the following words is used to explain how the text of the national difference is to be applied to the base IEC text: Addition / Add - An addition entai
39、ls adding a complete new numbered clause, subclause, table, gure, or annex. Addition is not meant to include adding select words to the base IEC text. Modication / Modify - A modication is an altering of the existing base IEC text such as the addition, replacement or deletion of certain words or the
40、 replacement of an entire clause, subclause, table, gure, or annex of the base IEC text. Deletion / Delete - A deletion entails complete deletion of an entire numbered clause, subclause, table, gure, or annex without any replacement text.

42、for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic elds. To this end and in addition to other activities, IEC publis
43、hes International Standards, Technical Specications, Technical Reports, Publicly Available Specications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may partic
44、ipate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement betwe
45、en the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publication
46、s have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
47、 misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding
48、national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certication bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any service
49、s carried out by independent certication bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publi
