Abstract

Specifies performance and general requirements for grey and ductile cast iron pipes and fittings up to nominal size DN 300 intended to be used where internal working pressure is considered negligible. An Appendix illustrates preferred designs of pipe fittings.

RECONFIRMATION NOTICE
Major stakeholders of this publication have reviewed the content of this publication and in accordance with Standards Australia procedures for reconfirmation, it has been determined that the publication is still valid and does not require change.
Certain documents referenced in the publication may have been amended since the original date of publication. Users are advised to ensure that they are using the latest versions of such documents as appropriate, unless advised otherwise in this Reconfirmation Notice.

Scope

This Standard specifies requirements for cast grey iron (flake graphite) and ductile iron non-pressure pipes and fittings up to nominal size DN 300, and intended to be used where the internal working pressure is negligible.
Where resistance to internal pressure is of prime importance, reference should be made to AS 2280, AS 2544 and AS 1724.
NOTE: Guidelines on information that should be provided by the purchaser or agreed upon at the time of enquiry or order are given in Appendix A. Typical designs of fittings are given in Appendix B.
