CEN/TR 1295-3:2007

This document specifies calculation methods for the structural design of water supply pipelines, drains and sewers, and other water industry pipelines, whether operating at atmospheric, greater or lesser pressure. It applies for the structural design of buried piping systems, made from all materials used for the conveyance of fluids under pressure or gravity conditions. Pipes to be designed for installations in abnormal or unusual conditions, e.g. in quick soils or a marine sea bed, are not covered by this document, it may require special engineering.
