Load Classifications

GATIC’s complete range of metal Access Covers, Road Grates and Frames are designed and tested in accordance with the Australian Standard AS3996:2006 and the 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 GATIC sales office for further information regarding selection of the appropriate class rating. 

AS3996 : 2006 - Australian Standard Load Classifications & Water Services Association of Australia (WSAA) Specification WSA PS-290
 
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.
 
WSAA Specification, WSA PS-290 Access Covers for Water Supply and Sewerage to AS3996, details increased serviceability design and ultimate limit state designs loads as that detailed in Table 3.1 of AS3996, refer table below, for Classes B, D, E and F covers. Gatic covers are designed and tested to the higher WSAA specification.

D Carriageways of roads and areas open to commercial vehicles 8000 7000 140 160 210 240
E General docks and aircraft pavements 13700 13700 267 280 400 420
F Docks and aircraft pavements subjects to high wheel loads 20000 20000 400 410 600 615
G Docks and aircraft pavements subject to very high wheel loads 30000 30000 600 600 900 900
 
NOTE: The above descriptions of classes of units reference to “wheel” should also be taken to include “dual wheels”. Norminal wheel loads are a guide only. Consideration should be be given to the type, size and pneumatic pressure of the load in application. A force of 1 kN is approximately equal to the weight of 100 kg.
 
EN124 : 1994 - European Standard Load Classification
 
The European Standard, EN124:1994 is GATIC’s nominated standard for International projects/applications outside of
Australia. Type testing under 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.
