Load Classifications

Home Load Classifications

Resin’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.

GROUP 1 CLASS A15

Areas which can only be used by pedestrians and pedal cyclists.

GROUP 2 CLASS B125

Footways, pedestrian and comparable areas, car parks or car parking decks.

GROUP 3 CLASS C250

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.

GROUP 4 CLASS D400

Carriageways of roads (including pedestrian streets),hard shoulders and parking areas, for all types of road vehicles.

GROUP 5 CLASS E600

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

GROUP 6 CLASS F900

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.

AS3996 : 2006 – Australian Standard Load Classifications

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)
Class Rating	Typical Use	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.
