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.
