Install the pergola according to the manufacturer’s instruction and make the center of side structure (top rail) to face the wind tunnel. Adjust the height of outlet of the wind tunnel if necessary. All the legs shall be secured to avoid moving during test.
The pergola shall undergo total five times of wind resistance test, with using different ranks of wind speed (10m/s, 15m/s, 20m/s, 24m/s and 28m/s.) from low to high. The wind shall be applied to the center of the side structure (top rail) and shall keep a steady speed for 30 seconds in each rank of test. The pergola should be checked thoroughly after each time of test.
The pergola shall have no damage or irreversible deformation after each rank of test. The test should be stopped when it becomes conscious of any damage or irreversible deformation.
Passed at all wind speeds
Resistance to Water Accumulation Testing
Acc. to DIN ISO 5912: 5.6 or by a rain test with about 5 Liter/min pro m2.
There shall be no water accumulation that will impair the structural safety of the pavilion.
No water accumulation.
Resistance to Snow Load Testing
Roof load capacity tested, test with 0.5 kN/m2, The load shall be distributed evenly on the roof.
There shall be no damage and function is well after test.
Applied the testing load of 600kg on roof. (25kg for each panel evenly distributed)
No permanent deformation was found after and during test.
