M&C’s complete range of SMC composite Access Covers, Gully Grates and Frames are designed and tested in accordance with the Australian Standard AS3996:2006 or European standard EN124:1994. The following table provides an overview of loading classes, its typical use and loading capacity. Appropriate class for a cover or grate depends upon the place of installation. Contact our sales office for further information regarding selection of the appropriate class rating.

EN124 : 1994 – European Standard Load Classification

EN 124 divides Manhole Covers and Drainage Gratings into 6 classes as follows : A15, B125, C250, D400, E600 and F900.
The classification denotes the test load expressed in kN.
Type testing under The European Standard EN124:1994 requires the Access Covers to meet the Minimum Design Load (kN) without exceeding the Permissible Permanent Set values. Refer to EN124:1994 subclause 8.3. for further details.

Areas imposing particularly high wheel loads, e.g.aircraft pavements.

Class Rating		Typical Use	Norminal Wheel Load(kg)	Servicibility Design Load(KN)	Ultimate Limit State Design Load(KN)
A		Areas which can only be used by pedestrians and pedal cyclists.	330	10	15
B		Footways, pedestrian and comparable areas, car parks or car parking decks.	2670	83	125
C		For gully tops installed in the area of kerbside channels of roads which when measured from the kerb edge, extend a maximum of 0,5m into the carriageway and a maximum of 0,2m into the footway.	5000	167	250
D		Carriageways of roads (including pedestrian streets),hard shoulders and parking areas, for all types of road vehicles.	8000	267	400
E		Areas imposing high wheel loads, e.g. docks, aircraft pavements.	20000	400	600
F		Areas imposing particularly high wheel loads, e.g.aircraft pavements.	30000	600	900

NOTE: A force of 1 kN is approximately equal to the weight of 100kg.

The Australian Standard, AS3996:2006 is GATIC’s nominated standard for projects/applications within Australia. Type testing under AS3996:2006 requires the Access Covers to meet the Ultimate Limit State Design Load (kN) without exceeding the Permanent Set and Deflection Limits. Refer to AS3996:2006 subclause 4.2.1. for further details.

	Class Rating	Typical Use	NOMINAL WHEEL LOAD (kg)		SERVICEABILITY DESIGN LOAD (kN)		ULTIMATE LIMIT STATE DESIGN LOAD (kN)
			AS3996	WSAA	AS3996	WSAA	AS3996	WSAA
	A	Areas (including footways) accessible only to pedestrians and pedal cyclists and closed to other traffic (extra-light duty)	330	330	6.7	6.7	10	10
	B	Areas (including footways and light tractor paths) accessible to vehicles (excluding commercial vehicles) or livestock (light duty)	2670	2670	53	54	80	82
	C	Malls and areas open to slow moving commercial vehicles (medium duty)	5000	5000	100	100	150	150
	D	Carriageways of roads and areas open to commercial vehicles (heavy duty)	8000	7000	140	160	210	240
	E	General docks and aircraft pavements (extra heavy duty – E)	13700	13700	267	280	400	420
	F	Docks and aircraft pavements subject to high wheel loads (extra heavy duty – F)	20000	20000	400	410	600	615
	G	Docks and aircraft pavements subject to very high wheel loads (extra heavy duty – G)	30000	30000	600	600	900	900

NOTES:

1 Nominal wheel loads are given for guidance only. Consideration should be given to the type, size and pneumatic pressure of the load applied.

2 Class B design loads exceed AS 5100.2 requirements for footway loading.

3 Class D design loads exceed AS 5100.2 requirements for a W80 wheel load.

4 Class C units are based on an intermediate load.

5 The serviceability load is set at 2/3 of the ultimate limit state design load.

6 A force of 1 kN approximately equal to the weight of 100 kg.
