scope:

This standard specifies the requirements and manufacture of reinforced concrete pressure pipe cylinder type, that is not prestressed, in sizes from DN/ID 250 to DN/ID 4000 inclusive. Pretensioned concrete cylinder pipe, in which the reinforcement is wrapped, under low tension, directly on to the steel cylinder is covered by this standard and is not normally manufactured in sizes above DN/ID 1400. Larger sizes can be manufactured based on the concepts of this standard. These types of pipes are designed for the internal pressure, external loads and bedding conditions designated by the purchaser. These types of pipes are also suitable for non-pressure load bearing applications
