AS/NZS 3725 Supp 1:2007

Gives additional guidance and commentary to AS/NZS 3725:2006. The Standard provides an agreed basis for determining the vertical working loads on installed steel-reinforced, fibre-reinforced and unreinforced concrete pipes and a range of installation conditions.

Scope

The main purpose of the Standard is to provide an agreed basis for determining the vertical working loads on installed steel-reinforced, fibre-reinforced and unreinforced concrete pipes and a range of installation conditions. The Standard relates these loads to the loads applied to sample pipes in the standard load tests, so that an appropriate ‘strength class’ of pipe can be selected from AS 4058 or AS 4139, as applicable, which will be suitable for the particular field application.
A secondary purpose of the Standard is to reduce the large variety of likely installation conditions and bedding choices to a small number of representative types.
