Describes requirements for construction, dimensions, materials and performance of plastics pipes of up to 400 mm nominal outside diameter, with or without perforations, and for associated fittings for normal field drainage. Includes methods of test, associated guidance and information of quality control testing and marking. Details determination of resistance to natural weathering, ultimate pipe stiffness and initial pipe stiffness, method for extrapolation of deflection data, determination of initial pipe stiffness, resistance to impact, flexibility, extensibility and joint tests, methods of test for stretched pipe and guidance on storage and installation.
