ČSN P CEN/TS 15223 This document specifies the procedure and gives guidance for structural design of buried thermoplastics piping systems under various conditions of loading for non-pressure application. This document can be used for pressure piping systems before applying operating pressure. This document is applicable to all solid and structured wall thermoplastics piping systems covered by an EN standard developed by CEN/TC 155. NOTE 1 - PE piping systems for gas infrastructure are covered in EN 12007-2 [1]. This document gives guidance for structural design by either validated field experience or calculation, and contents of EN 476 [2], EN 1295-1 [3] and EN 1610 [4] have been considered. 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. |
