Specifies the requirements for pipes. integral joints and post-formed bends of PVC-M for the conveyance of water and wastewater under pressure. The pipes are intended for use below ground and above ground where they are not exposed to direct sunlight.

This Standard specifies requirements for pipes, integral joints and post-formed bends of PVC-M for the conveyance of water and wastewater under pressure. The pipes are intended for use below ground and above ground where they are not exposed to direct sunlight.NOTE: If it is intended to use pipes complying with this specification for the conveyance of fluids other than water, the manufacturer should be consulted.PVC-M pressure pipes manufactured to this Standard, and associated fittings, should be used and installed in accordance with AS 2032, NZS 7643 and AS/NZS 2566, as applicable.Methods of demonstrating compliance with this Standard are given in Appendix A.
