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.
