Plastics piping systems for non-pressure underground drainage and sewerage. Polypropylene (PP) - Specifications for pipes, fittings and the system Ingestion-build-81500 the propagation properties of LiNbO31 Scope This part of EN 1852 specifies the requirements for solid wall pipes with smooth internal and external surfaces extruded from the same compound formulation throughout the wall, fittings and the system of polypropylene (PP) piping systems intended for use for: non pressure underground drainage and sewerage outside the building structure (application area code "U"), and non pressure underground drainage and sewerage for both buried in ground
