Plastics piping systems for non-pressure underground drainage and sewerage. Polyethylene (PE) - Specifications for pipes, fittings and the system1 Scope This Part of EN 12666 specifies the requirements for pipes, fittings and the system of polyethylene (PE) piping systems intended to be used 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 the ground within the building structure (application area code "D") and outside the building structure. This is reflected in
