11、4-2-11 makes reference to the Date of withdrawal, dow, of the relevant national standard. In this case there is no conflicting British Standard. 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 st
12、ates:The use of the certificate or mark licence in the running production 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 reco

14、andard calls for test procedures that may be injurious to safety or health if adequate precautions are not taken when conducting tests.Product certification. Attention is drawn to the fact that products conforming to this British Standard may be approved by BSI Product Certification, and that such c
15、ertification may be used for the purposes of participation in the CENELEC Certification Agreement. (Details of the BSI certification mark are given on the inside back cover.)Compliance with a British Standard does not of itself confer immunity from legal obligations.iiBSI 1997EUROPEAN STANDARDEN 501
