    8、006ii BSI 2006ForewordPublishing informationThis British Standard is published by BSI and came into effect on 29 December 2006. It was prepared by Subcommittee PRI/88/2, Plastics piping for pressure applications, under the authority of Technical Committee PRI/88, Plastics piping systems. A list of o

    9、rganizations represented on this committee can be obtained on request to its secretary.SupersessionThis British Standard supersedes BS 5392-1:1976, which is withdrawn.Relationship with other publicationsAttention is also drawn to BS 5391-1, which specifies requirements for compatible ABS pressure pi

    10、pe.Information about this documentThis British Standard can be referred to as BS 5392 instead of BS 5392-1 because there are no other parts to this standard. Future revisions of this standard will drop Part 1 from the identifier. In preparation for this, fittings conforming to this standard can be m

    11、arked with “BS 5392” instead of “BS 5392-1”.For this revision, the nominal size dimensions specified in Table 1 conform to BS ISO 727-2:2005. This revision also introduces nominal dimension sizes of 10 and 12.Product certification/inspection/testing. Users of this British Standard are advised to con

    12、sider the desirability of third-party certification/inspection/testing of product conformity with this British Standard. Appropriate conformity attestation arrangements are described in BS EN ISO/IEC 17025. Users seeking assistance in identifying appropriate conformity assessment bodies or schemes m

    13、ay ask BSI to forward their enquiries to the relevant association.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”.Commentary, explanation and general inf

    14、ormative material is presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with a British

    15、Standard cannot confer immunity from legal obligations. BSI 2006 1BS 5392-1:20061 ScopeThis British Standard specifies requirements for injection moulded pipe fittings made from acrylonitrile-butadiene-styrene (ABS) polymer, for solvent welding to ABS pressure pipe conforming to BS 5391-1:2006.This

    16、British Standard is applicable, for example, to fittings intended to be used for:a) chemical plants;b) industrial sewerage engineering;c) power engineering (cooling and general-purpose water supply);d) electroplating and pickling plants;e) the semiconductor industry;f) agricultural production plants

    17、;g) water treatment;h) potable water supply;i) low temperature applications down to p40 C.NOTE Pipe fittings conforming to this standard can be used for the transport of water intended for human consumption if it conforms to the relevant national, regional or local regulatory provisions applicable i

    45、 the marking shall be such that the marking is legible without magnification.9.4 Fittings shall be marked longitudinally with, as a minimum:a) the manufacturers name and/or trade mark;b) the number of this British Standard, e.g. BS 53921);NOTE Future revisions of this standard will drop Part 1 from

    46、the identifier because there are no other parts to this standard. In preparation for this, fittings conforming to this standard are allowed to be marked with “BS 5392” instead of “BS 5392-1”.c) the pressure class as given in Table 1, e.g. Class E;d) the nominal size, as given in Table 2, e.g. 4;e) t

    47、he material, i.e. ABS;f) the manufacturers information, including:1) the batch number or the production period (year and month), in figures or in code form; and2) if the manufacturer is producing at different sites, a name or code for each of the production sites.9.5 If the marking is printed on the

    48、 fitting, the colour of the printed information shall differ from the colour of the fitting.10 Stocking and transportFor the purpose of stocking and transport, fittings shall be protected from damage.1)Marking BS 5392 on or in relation to a product represents a manufacturers declaration of conformit

    49、y, i.e. a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is solely the claimants responsibility. Such a declaration is not to be confused with third-party certification of conformity.
