10、g Systems Components Standards Policy Committee. It supersedes BS 6130:1981, which is withdrawn. It is one of a series concerned with hose and hose assemblies for conveying petroleum products. It specifies requirements for ensuring the integrity and standardization of two types of metallic hose and
11、hose assembly for conveying asphalt and bitumen, which are hazardous materials at temperatures where they can flow readily. Corrugated hose with a temperature limit of 400 C has been introduced with details on construction, manufacture and testing. It is envisaged that rubber hose and hose assemblie
12、s will be specified in BS 6130-2. Asbestos has been specified for the strip wound hose constructions covered by this Part of BS 6130 as the only packing material that can meet the duty required although other alternative materials are being considered. The manufacture of all asbestos-based products
13、is covered by the requirements of the control of Asbestos at Work Regulations 1987, introduced on 1 March 1988. These set out comprehensive provisions covering work activities involving exposure to asbestos. Advice on how to comply with these regulations can be obtained from the manufacturers of the
14、 material, from the Asbestos Information Centre, Derby Road, Widnes, Cheshire WH8 9ND, from the local area office of the Health and Safety Executive or from the Environmental Health Department of the Local Authority. Particular note has to be taken of the Asbestos Products (Safety) Regulations 1985,
15、 made under the Consumer Safety Act 1978 and of the Asbestos (Prohibitions) Regulations 1988 made under the Health and Safety at Work etc. Act 1974, which prohibit the supply of products containing amosite or crocidolite and set out requirements for the labelling of all products containing asbestos.
16、 All the above legislation implements European Directives. Product certification. Users of this British Standard are advised to consider the desirability of third party certification of product conformity with this British Standard based on testing and continuing product surveillance which may be co
17、upled with assessment of a suppliers quality systems against the appropriate Part of BS 5750. Enquiries as to the availability of third party certification schemes are forwarded by BSI to the Association of Certification Bodies. If a third party certification scheme does not already exist, users sho
18、uld consider approaching an appropriate body from the list of Association members. 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 Standard does not of itsel
19、f confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 8, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be ind
