For pallets with smaller or larger areas, the force and the loading area shall be changed proportionally,whereby for the loading area the ratio of edge length shall be 1:1,5; however, the force shall be not below 3000 N (including weight of the plate), the size of the plate be not smaller than 0,20 m X 0,30m and its thickness be not less than 25 mm.
With the belt tensioned to suit operational conditions, a single force of 750 N (including weight of the plate) shall be applied on a steel plate 0,15 mx 0,25 m x0,025m in size. The plate shall be placed centrally between the edge supporting rollers in such a way that its longitudinal axis is parallel to the longitudinal axis of the belt. The deflection at the centre shall not exceed 0,01 Z3 where Z3 is the transverse distance between the supporting rollers (see Z3 in Figure 8).
The step shall be tested at the maximum inclination (inclined support) for which it is to be applied, together with rollers (not rotating), axles or stub shafts (if existing). It shall be subjected to a load pulsating between 500N and 3 000N at one frequency between 5Hz and 20Hz for at least 5 X 10° cycles whereby an undisturbed sinusoidal force flow shall be achieved. The load shall be applied perpendicular to the tread surface on a steel plate 0,20 m x 0,30 m in size and at least 25 mm thick, arranged as specified in 5.3.3.2.1, in the centre of the tread surface.
The step design shall be such that the structure can accommodate torsional loading equivalent to a±2 mm displacement of the trailer wheel centre, moving in an arc whose centre is the chain wheel centre. The±2 mm displacement is a relative to a trailer wheel to chain wheel centre distance of 400 mm. This ratio shall be maintained, when the 400 mm dimension is varied (see Annex F for test examples).
The dynamic test shall be adjustable to ensure that the specified deflections above are achieved throughout the test. It shall be applied with one frequency between 5 Hz and 20 Hz for at least 5 x 10° cycles whereby an undisturbed sinusoidal force flow shall be achieved.AS 1735.5 pdf free download.
