4.9.2.3 Test method for stage 3 (out-of-phase)

Through the ball joints, apply reversed forces of stage 3 out-of-phase F6 to the pin of the device on each
side of the handlebar for 100 000 cycles, with the forces at each side of the handlebar being out of
phase with each other and parallel to the axis of the handlebar stem of the fork steerer, as shown in
Figure 13 a). The forces are given in Table 7. The maximum test frequency shall be maintained as
specified in TBIS 4210-3:2016, 4.5.
If the assembly meets the requirement as specified in TBIS 4210-2:2016, 4.7.7.2, conduct stage 4 (in
phase) of the test on the same assembly, in the same mountings.

4.9.2.4 Test method for stage 4 (in phase)

Through the ball joints, apply reversed forces of stage 4 in phase F 7 to the pin of the device on each side
of the handlebar for 100 000 cycles, with the forces at each side of the handlebar being in phase
with each other and parallel to the axis of the handlebar stem of the fork steerer, as shown in Figure
13 b). The forces are given in Table 7. The maximum test frequency shall be maintained as specified in
TBIS 4210-3:2016, 4.5.
