Supplementary cementitious materials shall comply with AS 3582 or AS 3972.
6.1.3 Aggregates
Aggregates. where used, shall comply with AS 2758.1 and with any additional requirements that may, according to that Standard, need to be separately specified for a particular usage or application of the pipes.
Lightweight aggregate and non-ferrous metallurgical slag shall not be used in concrete for pipes and fittings.
NOTE: Attention is drawn to the fact that AS 2758. 1 includes a number of options, and cannot be used on its own as a specification for contract purposes. The particular option selected as appropriate to the intended usage of the pipes will, therefore, need to be separately referred to by the purchaser.

6.1.4 Water
Water added to the manufacturing process shall comply with the requirements of AS 1379.
8 ELASTOMERIC SEAL JOiNTS
Where elastorneric seal joints are employed, they shall provide a drip-tight seal. When tested in accordance with Appendix L, at the pressure specified in Clause 11.2, the joints shall provide a drip-tight seal at the manufacturer’s maximum recommended angular deviation.
9 DEFECTS
9.1 Cracks
Pipes shall be free from fractures and cracks wider than 0.1 mm and deeper than 0.3 mm.
9.2 Delamination
Pipes shall be free from any visible delamination.
9.3 Dents and bulges
