It is to be read in conjunction with BS EN 50144-1:1996 General requirements, which it supplements or modifies. The many references to Part 1 should be
10、 read as references to BS EN 50144-1:1996, which is the English language version ofEN 50144-1:1995.The foreword of EN 50144-2-9 makes reference to the “date of withdrawal”, dow, of the relevant national standard. In this case the relevant national standard is BS 2769-2.9:1984 which will be withdrawn
11、 on 1 December 1996 in accordance with the CENELEC Internal Regulations. Reference is also made to the application of CENELEC Memorandum No. 6 with regard to certification. Attention is drawn to Note 7 to Memorandum No. 6 which states:“The use of the certificate or mark licence in the running produc
12、tion may not go on for more than 60 months after dow. This should allow necessary changes in the production line and to use up supplies.Within the established period after dow the certificates and mark licences will have to be reconsidered and cancelled or reissued”.For tools intended to be used in
13、locations where special conditions prevail, as in ships and vehicles, and in hazardous locations, for example, where explosions are liable to occur, requirements additional to those specified in the standard may be necessary.This standard calls for test procedures that may be injurious to safety or
14、health if adequate precautions are not taken when conducting tests.Product certificationAttention is drawn to the fact that products conforming to this British Standard may be approved by BSI Product Certification, and that such certification may be used for the purposes of participation in the CENE
15、LEC Certification Agreement. (Details of the BSI certification marks are given on the inside back cover.)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 Stand
16、ard does not of itself confer immunity from legal obligations.Summary of pagesThis document comprises a front cover, an inside front cover, pages i and ii, the EN title page, pages 2 to 6, an inside back cover and a back cover.This standard has been updated (see copyright date) and may have had amen
