scope:

This part of EN 1852 specifies the requirements for solid wall pipes, 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 within the building structure (application area code "D") and outside the building structure. This is reflected in the marking of products by "U" and "UD". This standard covers PP materials without mineral modifiers. It also specifies the test parameters for the test methods referred to in this standard. This standard covers a range of nominal sizes, and pipe series and gives recommendations concerning colours. In conjunction with Part 2 and Part 3 of EN 1852 it is applicable to PP pipes and fittings, their joints and to joints with components of other plastics and non-plastics materials intended to be used for buried piping
systems for non-pressure underground drainage and sewerage. This standard is applicable to PP pipes and fittings with or without an integral socket.
