4、m No. 1 5 October 2001 Incorporating annex ZA. National foreword This British Standard is the official English language version of EN ISO 15667:2000. It is identical with ISO 15667:2000. The UK participation in its preparation was entrusted by Technical Committee EH/1, Acoustics, to Subcommittee EH/

5、1/4, Machinery noise, which has the responsibility to: aid enquirers to understand 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 develo

6、pments and promulgate them in the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publi

7、cations 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 section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI

8、 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 Standard does not of itself confer immunity from legal obligations. Summary
