Pipes shatl have cüameter ranging DN/IO 300 to DNfiD 4000. Larger size couid be rnanufactured based on the concepts of this standard. This type ol pipe is designed for the internal pressure, external loads, and bedding conditions designated by the purchaser. Maximum design pressure shail not exceed 500 kPa. The above limit shall be increased to 2000 kPa in case ot distributed reinforcement gipes (DRP).
