A list of organizations represented on this committee can be obtained on request to its secretary. From 1 January 1997, all IEC
5、publications 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 fiom one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is dram to the
