BS EN 124-3:2015 PDF Download

BS EN 124-3:2015 is a European Standard that specifies the requirements for gully tops and manhole tops made of steel or aluminium alloys. These gully tops and manhole tops are used to cover gullies, manholes, and inspection chambers in areas that experience pedestrian and/or vehicular traffic. The standard covers various types of areas, ranging from those only used by pedestrians and pedal cyclists to carriageways of roads, hard shoulders, and parking areas for all types of road vehicles. It also includes areas with high wheel loads, such as docks and aircraft pavements.

The standard provides guidance for the combination of covers/gratings made from steel or aluminium alloys with frames according to EN 124-2 and other related standards. The fabrication methods allowed by this standard are limited to cold forming, mechanical crimping, or welding together component parts made from metal plate, strip, bar, or rolled/extruded metal sections.

However, there are certain exceptions to the standard. It does not apply to manhole tops and gully tops made of aluminium tread plates for use in specific areas, such as carriageways of roads and areas imposing high wheel loads. It also excludes concave gratings for certain classes installed in carriageways of roads and hard shoulders. Additionally, the standard does not apply to gratings/covers as part of prefabricated drainage channels, floor, and roof gullies in buildings, and surface boxes.
