AS 1235-2000 Road Vehicle Roof Bar Testing

Canopies are independently tested to the loading requirements of Australian Standard AS 1235-2000 Road Vehicles – Roof Load carriers – Roof Bars Sec 5.1, 5.2 & 5.3. All our dual cab canopies have been found to satisfy the loading requirements of this portion of the Australian Standard for a uniformly distributed roof bar load of 100kg 

Testing was conducted to the loading requirements of AS1235-2000 on two Rhino-Rack cross bars attached with an artificial gutter roof rack system, which was fitted to our TJM dual Canopies. The roof rack was secured to the TJM Canopies in defined locations as shown in figure 1, All testing was conducted using a specially manufactured test box, constructed to the dimensional requirements as prescribed in AS1235-2000.

The test procedure - Three individual load tests: 

  1. Resistance to lift test 

    A peak force of 309kg in a vertical direction for 10 minutes, the roof bars remained fixed to the canopy and there was no evidence of permanent deformation visible on the roof bars or the canopy
     
  2. Slide resistance test 

    This test involved the application of a peak force of 424.3kg in the longitudinal forward direction. The measured deflection was within the required limits and there was no evidence of permanent deformation visible on the roof bars or the canopy
     
  3. Slide resistance test under quasi-static force applied at 20deg to the vehicle longitudinal axis. 

    This test involved a peak force of 440.4kg on the test box in the forward direction at an angle of 20 degree’s to the vehicle’s longitudinal axis. The measured deflection was within the required limits and there was no evidence of permanent deformation visible on the roof bars or the canopy.
