EN 14766:2005 (E)Dimension in millimetresKey1 Rigid mount incorporating head bearings2 Brake mounting-point3 Test adaptorFigure 37 — Fork for hub/disc-brake – repeated brake-torque test4.9.7.3.2 Test methodMount the fork in a fixture representative of the head-tube and gripped in the normal head-bearings with the axis ofthe fork-stem vertical. Fit an axle to the fork, and mount on the axle a pivoted, straight adaptor as shown inFigure 37 to provide a torque-arm of 330 mm in length and a suitable attachment for the brake mounting-point.Apply repeated, horizontal, dynamic forces of 600 N rearward to the end of the torque-arm parallel to the plane ofthe wheel (as shown in Figure 37) for 12 000 test cycles with a test frequency not exceeding 25 Hz.60
