14、sh Standards are subject to periodical review. Suggestions for improvements will be recorded and in due course brought to the notice of the committees charged with the revision of the standards to which they refer. A complete list of British Standards, numbering over 5000, fully indexed and with a n
15、ote of the contents of each, will be found in the British Standards Yearbook. The BS Yearbook may be consulted in many public libraries and similar institutions. This British Standard has been prepared under the authority of the Electrical Industry Standards Committee, as a result of proposals by th
16、e Codes of Practice Committee for Electrical Engineering, in view of the increasing use of plastics conduits for electrical installations in the United Kingdom and other countries. Parts 1 and 2 dealt respectively with rigid PVC conduits and fittings in metric and inch dimensions. This Part is in cl
17、ose agreement with Part 1 and differs from it only in those respects necessary to adopt the requirements of Part 1 to pliable rather than rigid conduits. It is thus also in close agreement with the requirements of CEE1) Publication 26: “Rigid conduits of polyvinyl chloride for electrical installatio
18、ns and their fittings” and with a draft CEE recommendation for pliable conduits of self-extinguishing plastics material based on CEE 26 presently under review. This Part of this British Standard differs from Parts 1 and 2 as to material in that it allows the use of any plastics self-extinguishing ma
19、terials which meet the requirements of the tests specified and is not limited to PVC. The materials are, however, still classified according to their behaviour at low temperatures as in Part 1. A British Standard does not purport to include all the necessary provisions of a contract. Users of Britis
20、h Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
