28 - B1 SCOPE

Specifies methods for calculating the working loads, resulting from overlaying material and superimposed dead and live loads, which act on buried vitrified clay pipelines. From these values, a design crushing load can be calculated for use in selecting an appropriate crushing strength class of pipes and fittings complying with AS1741, Vitrified clay pipes and fittings with flexible joints - Sewer quality.

This Standard sets out requirements and provides data for-(a) calculating the working loads on buried vitrified clay pipes due to-(i) materials covering the pipes; and(ii) superimposed loads; and(b) selection of the crushing strength class for combinations of installation condition, support type, working load and factor of safety.AS 1741 specifies the minimum crushing load for each nominal size and crushing strength class of vitrified clay pipes.In addition, the Standard classifies installation conditions and support types and specifies requirements, including compaction, for the embedment.
