4、s have the number 60000 added to the old number. For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that
5、 CEN and CENELEC standards normally include an annex which lists nonnative references to international publications with their corresponding European publications. The British Standards which implement these intedonal or European publications may be found in the BSI Standards Catalogue under the sec
