Its objective is to satisfy and exceed our customers' requirements and expectations in both quality products and services. Rigorous testing and quality control throughout the production process are audited and continuously improved to ensure that GATIC®’s products comply with Australian Standard AS3996 and European Standard EN124.
To ensure consistent quality and performance, all GATIC® access covers and grating are inspected as follows prior to delivery.
- Dimensional tolerance check
- Material compositions
- Batch traceability data
- Load testing (in accordance with AS3996 or EN124)
- Keyhole gauge fit
- Machining
- Anti-rocking
- Painting surfaces
- General appearance
- Packaging
GATIC® Mechanical Testing Laboratory
GATIC®’s Mechanical Testing laboratory is recognised and accredited by the National Association Testing Authorities, Australia (NATA Laboratory Accreditation No. 14262). Load tests are carried out on the capacity test rig as part of GATIC®’s Quality Assurance program in accordance with Australian Standard AS3996 and European Standard EN124. Test reports are available on request.
GATIC® also undertakes the following tests both inhouse and through independent institutes:
- Bicycle Tyre Penetration Resistance Test
- Hydraulic Flow Rate Test
- Gas-tightness Test
- Water-tightness Test
Load testing under Australian Standard AS3996 involves Type Testing of a unit to ensure the product achieves its Load Classification and Ultimate Limit State Design Load (kN).
Testing involves:
- Five repetitions of the serviceability design load is applied to the unit in accordance with AS3996:2006 subclause 4.2.1.1, measurement of Ultimate Limit State Design Load (kN). Set must not exceed the Permanent Set and Deflection Limits (refer to Table 4.2 in AS3996:2006 subclause 4.2.1.2).
- Followed immediately by one application of the ultimate limit state design load for a minimum of 30 seconds. The unit must sustain the above tests without visible cracking, collapse or other forms of structural failure.
Load Classifications
GATIC®’s complete range of metal Access Covers, Road Grates and Frames are designed and tested in accordance with the Australian Standard AS3996:2019. 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.
Australian Standard - AS3996:2019
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 | AS3996 | AS3996 | ||
| A | Footways and areas accessible only to pedestrians and pedal cyclists | 330 | 6.7 | 10 |
| B | Footways that may be mounted by a vehicle or livestock, and light tracker paths | 2670 | 53 | 80 |
| C | Malls and pedestrian areas open to slow moving commercial vehicles | 5000 | 100 | 150 |
| D | Carriageways of roads and areas open to commercial vehicles | 8000 | 140 | 210 |
| E | General docks and aircraft pavements | 13700 | 267 | 400 |
| F | Docks and aircraft pavements subject to high wheel loads | 20000 | 400 | 600 |
| G | Docks and aircraft pavements subject to very high wheel loads | 30000 | 600 | 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.
