[Pending Revision]Precast concrete pipes (pressure and non-pressure)
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.
