5.4.2 Test method 2

This test is similar to that described in 5.4.1 except the dropping height.

As shown in Figure 7, mount the fork used for the test in 5.4.1 and assemble a low-mass roller in the fork.
Raise the striker to a height of 600 mm above the roller and release it to strike the roller against the rake
of the fork. The section applies to forks in TBIS 4210-2:2017, 4.9.5.1.

5.4.3 Test method 3

Apply a torque of T to the assembly and maintain for 1 min in each direction of possible rotation about
the steerer axis. The torque is given in Table 8, and a typical example of test equipment is illustrated in
Figure 9.
