a) Class H 1,5: Areas where no load is expected
b) Class K 3: Areas without vehicular traffic, such as dwellings, commercial and some public buildings
c) Class L 15: Areas with light vehicular traffic, such as in commercially used premises and public areas
d) Class R 50: Areas with vehicular traffic, such as in commercially used premises and factories e) Class M 125: Areas with vehicular traffic, such as car parks, factories and workshops
f) Class N 250: Heavy duty industrial areas subject to forklift traffic, such as food processing areas, chemical or process plants
g) Class P 400: Extra-heavy duty applications including food processing areas, chemical or process plants, where gullies are subjected to industrial forklift trucks and/or where heavy vehicles are manoeuvring
Classes E 600 and F 900 gully tops conforming to the EN 124 series may be used for all areas subject to special stresses such as exhibition halls, market halls, factory sheds and aircraft hangars
The selection of the appropriate class is the responsibility of the designer Where there is doubt of the class to be used, the next highest class should be selected
5 Materials
The materials used shall withstand the stresses likely to occur during installation and operation and shall comply with the requirements specified in Clause 6, such that there shall be no deformation of the access cover or other damage likely to impair function or cause injury to health
6 Design and construction
6.1 General requirements
Access covers shall be designed and manufactured to ensure their function and the compatibility of seatings between frame and cover Cushioning inserts may be used
When in position, it shall not be possible for covers to be dislodged from the frame, but they shall be easy to open The upper surfaces of frame and cover shall be flush
6.2 Appearance
Access covers shall be free from sharp edges and imperfections (e.g bubbles, cracks or unevenness) which could impair functioning or cause injury to people
6.3 Clear opening of access covers for man entry
The clear opening of access covers designed for man entry shall comply with the provisions of EN 476 and the safety requirements in force at the place of installation
6.4 Edge protection for access covers of reinforced concrete
For reinforced concrete access covers, the edges and contact surfaces of the seating between frame and cover shall be protected with hot-dip galvanized steel or cast iron or materials of equivalent properties
Trang 86.5 Tightness
6.5.1 General
Where tightness is required it shall be tested in accordance with 7.3 There are three classes of tightness
as follows:
6.5.2 Watertightness: Class Wt
Watertight access covers shall prevent the ingress of surface water which does not exert hydrostatic pressure when tested in accordance with 7.3.1 This can be achieved, for example, by providing a mechanical connection of frame and cover or by way of an appropriate design of these components
6.5.3 Odourtightness: Class Ot
Odourtight access covers shall prevent the escape of foul air Odourtightness is assumed if the access cover is tight when tested in accordance with 7.3.2
6.5.4 Backflow tightness: Class Bt
Backflowtight access covers shall, in the event of surcharge in the drainage system, prevent backflow, at
a pressure of up to 50 kPa (0,5 bar) of water from escaping from the access cover when tested in accordance with 7.3.3; they shall also be watertight in accordance with 6.5.2 and odourtight in accordance with 6.5.3
6.5.5 Additional requirements
If a higher tightness is required, e.g for toxic and/or explosive gases, the design and the test methods shall be agreed between the manufacturer and user
If an additional inner cover is provided for sealing purposes, the outer cover shall be designed to restrict water ingress Water that has penetrated through the top cover shall not collect on the inner cover, but shall be drained
7 Test methods
7.1 Loading test
Access covers shall be subjected to a loading test as specified in EN 1253-1:2015, 5.6, or
EN 1253-2:2015, 5.3, in order to establish their class
7.2 Appearance and dimensions
The requirements specified in 6.2, 6.3 and 6.4 shall be checked by visual examination Dimensions shall
be measured to an accuracy of ± 1 mm
7.3 Tightness
7.3.1 Watertightness
The access cover shall be flooded with a (10 ± 1) mm head of water for a period of (15 ± 1) min The test shall be deemed to have been passed if, during this period, no water has penetrated to the underside
7.3.2 Odourtightness
The access cover shall be subjected from below to a hydrostatic pressure of ≥ 500 Pa (≥5 mbar) The test shall be deemed to have been passed if, over a period of (15 ± 1) min, no water has escaped at any point
