Description of BS EN 17670-2:2023 2023

This document specifies the definitions and requirements for unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) road gullies intended for use in non-pressure underground drains and sewers for surface water having a maximum depth of 4 m from ground level to the lowest point of the internal surface of the road gully. Road gullies complying with this document are intended to be used in pedestrian or vehicular traffic areas outside the building structure. NOTE 1 Products complying with this document can also be used in non-traffic areas. NOTE 2 Road gullies can be subject to national regulation which limit the maximum installation depth and / or local provisions. The installer checks for compliance prior to installation. Road gullies complying with this document are made from a prescribed set of components that are manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) and assembled together. Road gullies complying with this document may be equipped with optional devices (e.g. removable sand or silt bucket, leaf separator etc.), however the performance of these optional devices is not covered within the scope of this document. Road gully components can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, low-pressure moulding, blow moulding, thermoforming or fabricated. NOTE 3 Products complying with this document can be installed in underground applications without additional static calculation. NOTE 4 The complete road gully assembly can also include non-plastic items (near surface or surface components for example) which are not covered by this document. NOTE 5 The complete road gully assembly can be supplied with covers, frame covers and gratings complying with the relevant part of EN 124 which are not covered by this document. However, reference is made to this document for geometrical characteristics where applicable. NOTE 6 Road gullies can be site assembled from different components, but can also be manufactured as a single unit. This document covers: - road gullies with or without sand / silt trap; - road gullies with or without water seal preventing odour release; - road gullies where the traffic load will or will not be carried by the complete gully (resp. "Direct loaded gullies" or "Indirect loaded gullies").
