scope:

Gives recommended practices for the installation of piping systems made of unplastized poly(vinyl chloride) (PVC) in the field of external rainwater discharge systems for above ground use. It gives installation practices which are applicable to PVC-U rainwater discharge pipework based on pipes and fittings which conform to part 1 of prEN 12200. The existing general requirements that are applicable to the calculation of the sizing of rainwater installations in other materials are also valid for PVC-U systems. References are made to pipes and fittings manufactured in other materials which may be connected to the PVC-U piping components conforming to this standard and to the techniques of jointing to these dissimilar materials. Provides recomended installation techniques but it is essential that the manufacturer's fixing instructions and material handling advice are taken into account to ensure good, sound and troublefree rainwater downpipe systems.
