3、lish language version of EN60534-3-3:1998. It is identical with IEC60534-3-3:1998. The UK participation in its preparation was entrusted by Technical Committee GEL/65, Measurement and control, to Subcommittee GEL/65/2, Elements of systems, which has the responsibility to: aid enquirers to understand
4、 the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this
5、subcommittee can be obtained on request to its secretary. From1January1997, all IEC publications have the number60000added to the old number. For instance, IEC27-1has been renumbered as IEC60027-1. For a period of time during the change over from one numbering system to the other, publications may c
6、ontain 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 correponding European publications. The British Standards which implement these int
7、ernational or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provi
8、sions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
