→At the edges of the cover and the frame a test block of 75mm diameter, equipped with a rubber sheet of 75mm diameter with a thickness of 10mm, hardness (60±5)゜, shore A at the bottom, shall be applied at the test points. The axis centre of the test block is positioned at the gap between cover/grating and frame. A gradually increasing test load from 0Kn to 50kN is to be applied 3 times with a rate of 1kN/s to 5kN/s. Under effect of the test load the tilting height between the top of the frame and the top of the cover shall be measured.
