This British Standard specifies requirements for the construction, dimensions, materials and performance of plastics pipes of up to 400 mm nominal outside diameter, with or without perforations, and for any associated fittings for normal field drainage.
No restrictions are placed on the type of plastics material to be used.
Methods of test, associated guidance and information on quality control testing are given in appendices.
