The difference type is noted on the rst line of the National Difference in the standard. The standard may not i
39、nclude 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 principles and requirements, elimination of which would compromise safety for consumers and users of prod

These requirements reect national safety practices, where empirical substantiation (for the IEC or national requirement) is not available or the text has not been included in the IEC standard. DC These
41、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 based on editorial comments or corrections. Each national difference contains a description of what
42、 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 entails adding a complete new numbered clause, subclause, table, gure, or annex. Addition is not meant
43、 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 replacement of an entire clause, subclause, table, gure, or annex of the base IEC text. Deletion
44、 / Delete - A deletion entails complete deletion of an entire numbered clause, subclause, table, gure, or annex without any replacement text.

46、ation 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 publishes Internatio
47、nal 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 participate in this
48、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 between the two org
49、anizations. 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 Publications 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 c
