Specifies requirements and recommended methods for installing acrylonitrile butadiene styrene (ABS) pipelines, above or below ground, for both pressure and non-pressure applications.

This Standard specifies requirements and sets out recommended methods for installing acrylonitrile butadiene styrene (ABS) pipelines, above or below ground, for both pressure and non-pressure applications. Information is included on the selection, storage and handling, of ABS pipes.NOTE: The suitability of ABS for conveyance of a range of chemicals is tabulated in Appendix A.
