It is identical with IEC 61131-52000. The UK participation i
4、n its preparation was entrusted by Technical Committee GEU65, Measurement and control, to Subcommittee GEU65/2, Elements of systems, which has the responsibility to: - - aid enquirers to understand the text; present to the responsible internationaUEuropean committee any enquiries on the interpretati
5、on 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 subcommittee can be obtained on request to its secretary. From 1 January 1997, all IEC publications hav
6、e 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 CEN a
7、nd CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the secti
8、on 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 provisions of a contract. Users of British Standards are responsible for their correct application,
9、Compliance with a British Standard does not of itself confer immunity from legal obligations.
