5、e, 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. From1January1997, all IEC publications have the number60000 added to the
6、 old number. For instance, IEC27-1 has been renumbered as IEC60027-1. 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 and CENELEC Standards normally in
7、clude an annex which lists normative references to international publications with their corresponding European publications. The BritishStandards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standa
8、rds 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. Compliance with a British Standar
9、d does not of itself confer immunity from legal obligations.
