BS EN 1433:2002 pdf free.Drainage Channels For Vehicular And Pedestrian Areas – Classification, Design And Testing Requirements, Marking And Evaluation Of Conformity.
This European Standard specifies requirements for linear drainage channels for the collection and conveyance of surface water when installed within areas subjected to pedestrian and/or vehicular traffic.
These channels are defined as either Type I, which requires no further support or Type M, which requires additional support to accommodate the vertical and horizontal loads in service, in accordance with the manufacturers’ recommendations.
This standard specifies requirements for gratings and covers integral with a linear drainage system. This standard applies to grid units, slot units and kerb units up to a clear opening of 1 000 mm.
This standard specifies definitions, classes, design and testing requirements, marking and quality control for drainage channels.
4 Classification
Drainage channels shall be classified as follows according to their intended use (see also clause 5):
A15, B 125 C250, D400, E600, F900.
5 Places of installation for drainage channels
The appropriate load class of drainage channel to chose depends upon where the channel is to be installed. Typical places of installation have been divided into groups numbered 1 to 6 as listed below. Figure 10 and Figure 11 show the location of some of these groups in a highway environment. An indication as to which minimum load class of drainage channel should be selected is shown in parenthesis for each group. The selection of the appropriate load class is the responsibility of the designer.
Where there is any doubt, a higher load class should be selected.
Groups of installation:
Group 1 (mm. class A 15)
Areas which can only be used by pedestrians and pedal cyclists.
Group 2 (mm. class B 125)
Footways, pedestrian areas and comparable areas, private car parks or car parking decks.
Group 3 (mm. class C 250)
Kerb sides (Figure 10) and non-trafficked areas of hard shoulders and similar; Kerb units are always group 3.
Group 4 (mm. class D 400)
Carriageways of roads (including pedestrian streets), hard shoulders (Figures 10 and 11) and parking areas, for all types of road vehicles.
Group 5 (mm. class E 600)
Areas subjected to high wheel loads, e. g. ports and dock sides.
Group 6 (class F 900)
Areas subjected to especially high wheel loads e. g. aircraft pavements.
