Sets out acceptable methods for calculating the vertical working (service) loads, resulting from overlying materials and superimposed dead and live loads, which act on buried concrete pipes. Users are also referred to AS 4058-1992 Precast concrete pipes.

This Standard sets out methods and provides data for-(a) calculating the vertical working loads on buried concrete pipes due to-(i) the materials covering the pipes; and(ii) superimposed loads; and(b) relating the minimum test cracking load to be applied to sample concrete pipes, in accordance with AS 1342 and AS 1392, 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.
