We at Joyyr make ductile iron manhole covers ,gully grating according to EN124:2015.

EN124 Classfication and Loading Group

Under BS EN 124:2015, manhole covers, access covers and gully grates are graded by different loading applications,,so,there are 6 classes as : class A15, B125, C250, D400, E600 and F900. The classification denotes the test load expressed in kN.

Loading Group	Installation Area	BS EN 124 Class	BS EN 124 Test Load
Group 1	For use in pedestrian areas where vehicles have no access	A15	15kN (1.5 tonnes)
Group 2	For use in car parks & pedestrian areas where infrequent vehicle access is likely (incl. driveways)	B125	125kN (12.5 tonnes)
Group 3	For access covers & gully gratings in areas of slow moving, heavy traffic; also for gully gratings in certain carriageway areas (see full definition above)	C250	250kN (25 tonnes)
Group 4	For use in carriageways of roads, hard shoulders and parking areas	D400	400kN (40 tonnes)
Group 5	For use in areas where high wheel loads are present	E600	600kN (60 tonnes)
Group 6	For use in areas where extremely high wheel loads are present	F900	900kN (90 tonnes)
