11、red to as BS 5391 instead of BS 5391-1 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, pipes conforming to this standard can be marked with “BS 5391” instead of “BS 5391-1”.For this revision, the nomi

This revision also introduces nominal dimension sizes of 10 and 12.Maximum sustained working pressures are based on a recommended working stress for the material of 7.5 MP

Users of this British Standard are advised to consider the desirability of third-party certification/inspection/testing of product conformity with this Br

14、itish Standard. Appropriate conformity attestation arrangements are described in BS EN ISO/IEC 17025. Users seeking assistance in identifying appropriate conformity assessment bodies or schemes may ask BSI to forward their enquiries to the relevant association.Presentational conventionsThe provision

17、ard specifies requirements for pipe made from acrylonitrile-butadiene-styrene (ABS) polymer for the conveyance of liquid and gaseous fluids as well as solid matter in fluids.This British Standard is applicable, for example, to pipes intended to be used for:a) chemical plants;b) industrial sewerage e

18、ngineering;c) power engineering (cooling and general-purpose water supply);d) electroplating and pickling plants;e) the semiconductor industry;f) agricultural production plants;g) water treatment;h) potable water supply;i) low temperature applications down to p40 C.NOTE Pipe conforming to this stand

19、ard 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 in the place of use. For products in the United Kingdom, attention is drawn to The Water Supply (Water Fittings) Regulations 1999 1.2
