For instance, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over

6、 from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European P
