    4、nts National foreword This British Standard is the official English language version of EN ISO 14660-1:1999. It is identical with ISO 14660-1:1999. This standard, together with BS 8888 and other implemented European and International Standards listed in annexes A and B of BS 8888, suppersedes all pa

    5、rts of BS 308 which are withdrawn. The European and International Standards that were implemented to form subsections of Part 3 of BS 308 and were dual numbered, are now listed by the implementation number only, e.g. BS EN ISO xxxx. The pocket guide previously available is currently under review. Th

    8、ttention is drawn to the fact that CEN and 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

    9、 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 provisions of a contract. Users of British Standards are res

    10、ponsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
