11、ing separate Parts: Part 1: Steel nails; Part 2: Copper nails; Part 3: Aluminium nails. This Part of the standard has been prepared under the authority of the Hardware and Ironmongery Industry Standards Committee. It is expressed solely in metric units and relates to 6types of copper nails at presen
12、t in common use and to the roves manufactured for use with the two types of copper boat nails specified; it is thus not confined to nails for buildings. No attempt has been made to specify “specials”. For the benefit of those not conversant with metric diameters of nails, each table in this standard
13、 includes a separate column showing the nearest former standard wire gauge (s.w.g.) numbers. These do not form part of the specification. Their inclusion is only intended to be temporary and is planned to be reconsidered by31December1976. Inch equivalents, if required, may be determined from BS350,
14、“Conversion factors and tables”. This Part of the standard replaces BS1202-2:1966 which was prepared at the request of nail users and manufacturers with the approval of the Code of Practice Drafting Committees responsible for CP142, “Slating and tiling and CP143, Sheet roof and wall coverings”. A Br
15、itish 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 of pages This document comprises a fr

36、n trade mark of the British Standards Institution. A licence to use the Kitemark on or in relation to a product will be granted to any manufacturer or producer who demonstrates that he can and will be able consistently to make that product to a specified British Standard. His capability of doing so
37、is initially assessed by inspection of his production process, quality control organization and test facilities, and by independent testing of a sample of the product against all the criteria of the relevant standard. The licensee is required to accept, and to operate in accordance with, a BSI schem
38、e of supervision and control which identifies the tests to be carried out during manufacture and on the completed product and specifies the frequency of such testing. BSI carries out unannounced inspection visits to the manufacturers works and audit testing of the product, and may withdraw the licen
39、ce for any failure of the manufacturer to comply with the relevant standard or with the requirements of the scheme of supervision and control. The presence of the Kitemark on or in relation to a product is an assurance that the goods have been produced under a system of supervision, control and test
40、ing, operated during manufacture and including periodical inspection of the manufacturers works in accordance with the certification mark scheme of BSI.
