scope:

This Standard sets out methods and provides data for the following:

(a) Calculating the vertical working loads on buried concrete pipes due to-

(i) the materials covering the pipes; and

(ii) superimposed loads.

(b) Relating the minimum proof test load to the selection of appropriate pipes made in accordance with either AS 4058 or AS 4139, to the calculated vertical working loads on concrete pipes installed under particular conditions, including that of combined vertical load plus internal pressure.

In addition, the Standard classifies types of pipe installation and types of bedding and sets minimum requirements for the soil materials around the pipes and compaction of these materials.

NOTE: AS/NZS 3724 Supp 1 is a Commentary on this Standard. It provides further information relevant to many Clauses in this Standard. The Supplement, while bound with the Standard, is 'informative' and does not form an integral part of the Standard.
