For different classes of manhole tops or gully tops provisions in the place of installation shall be taken into account. The appropriate class of a manhole top or a gully top to be used depends upon the place of installation. The various places of installation have been divided into groups numbered 1 to 6, as listed below. Figure 5 and Figure 6 show the location of some of these groups in a highway environment. The minimum class recommended for use in each group is shown in brackets. The selection of the appropriate class and the material is the responsibility of the specifier. Where there is any doubt, the stronger class should be selected. — Group 1 (at least class A 15): Areas which can only be used by pedestrians and pedal cyclists. — Group 2 (at least class B 125): Pedestrian areas and comparable areas, car parks or car parking decks. — Group 3 (at least class C 250): For gully tops, installed in the area of kerbside channels of roads (Figure 5) which, when measured from the kerb edge, extends a maximum of 0,5 m into the carriageway and a maximum of 0,2 m into the pedestrian area.

EN 124-1:2015 (E) 12 — Group 4 (at least class D 400): Carriageways of roads (including pedestrian streets), hard shoulders (Figure 6) and parking areas, for all types of road vehicles. — Group 5 (at least class E 600): Areas imposing high wheel loads, e.g. docks, aircraft pavements. — Group 6 (class F 900): Areas imposing particularly high wheel loads, e.g. aircraft pavements. NOTE 1 Compliance of the product with the respective part of EN 124 series does not replace the responsibility of the user to ensure that the gully top or the manhole top is correctly installed and its elements (frame and grating/cover) have the necessary performance values. For concave gratings the places of installation shall be limited to the following places of intended uses: — Groups 1, 2 and 3; — Group 4, for parking areas only.
