Abstract
Proposes minimum requirements for the materials to be used in, and the manufacture of, controlled quality precast concrete pipes, and proposes methods of sampling, testing and classifying concrete pipes manufactured in accordance with this Standard. It applies to circular precast pipes, manufactured from concrete, unreinforced or with circumferential steel reinforcement, that are intended for pressure or non pressure water supply, drainage, waste water or sewerage applications or service ducts.
Scope
This Standard describes minimum requirements for materials and manufacture of controlled quality precast concrete pipes. It also describes minimum requirements for sampling, testing and classifying concrete pipes manufactured in accordance with this Standard.
This Standard applies to circular precast pipes manufactured from concrete, unreinforced or with circumferential steel reinforcement, that are intended for pressure or non-pressure water supply, drainage, sewerage or service duct applications.
This Standard does not apply to the following:
Cast in situ pipes, box culverts, or structural members covered by other Australian Standards.
Precast prestressed concrete pipe, embedded steel cylinder pipe, and fibre-reinforced concrete pipe or precast concrete cylindrical access chamber components, or pipes made of other materials.
Requirements for fittings fabricated from pipes complying with this Standard are not specified in this Standard.
Requirements for ordering and supplying concrete pipes are given in Section 6 (see Note 2).
This Standard does not cover the assessment of external service loads to which a pipe will be subjected in particular installation conditions. Therefore, purchasers should specify pipe design characteristics and routine testing requirements that are appropriate to the intended embedment and service conditions. Where a purchaser is not the concrete pipe asset owner, the purchaser should consult with the asset owners designer or specifier to determine these requirements, prior to ordering.
AS/NZS 3725 should be referred to for the selection, design and specification of buried concrete pipe installations.
