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5、rts of BS 308 which are withdrawn.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

A list of organizations represented on this committee can be obtained on request to its secretary. Cross-references A
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
