Plastic piping systems - Structural design of buried thermoplastics piping systems - Procedure and guidance under various conditions of loading

Publication date:   Nov 30, 2023

Scope

This document specifies the procedure and gives guidance for structural design of buried
thermoplastics piping systems under various conditions of loading for nonpressure
application. This document can be used for pressure piping systems before applying
operating pressure.
NOTE 1 Piping systems for gaseous fluids, district heating and industrial applications are
excluded.
This document is applicable to all solid and structured wall thermoplastics piping systems
covered by an EN standard developed by CEN TC 155. Operating conditions for nonpressure
piping systems as defined in EN 476 shall be respected.
This document gives guidance for structural design by either validated field experience or
calculation.
At the design stage, precise details of types of soil and installation conditions are not always
available. The choice of design assumptions is left to the judgement of the
designer/specifier. In this respect, this technical specification provides general indications
and advice.
NOTE 2 It is the responsibility of the designer/specifier to make the appropriate selection of
the design aspects, taking into account any relevant National regulation and installation
practices or codes.
