Over deze norm
It is applicable for drainage systems inside dwellings and commercial, insitutional and industrial buildings. The standard does not cover systems ventilated by air admittance valves. It describes a method of calculating the hydraulic adequacy of roof drainage systems. It also sets standards or the layout and installation of roof drainage in so far as they affect flow capacity. Applies to all roof drainage systems where the outlets are large enough not to limit the flow capacity of he gutter (i.e. free discharge conditions). It applies to all materials used for roof drainage systems, irrespective of their method of manufacture. Provision is made for national or local authorities to lay down meterological requirements. National and local regulations or practice are listed in annex B.
