EN 14766:2005 (E)4.13.3 Pedal/pedal-spindle assembly – static strength test4.13.3.1 RequirementWhen tested by the method described in 4.13.3.2, there shall be no fractures, visible cracks, or distortion of thepedal or spindle that could affect the operation of the pedal and pedal-spindle.Key1 Rigid mount4.13.3.2 Test methodFigure 43 — Pedal/pedal-spindle assembly – static strength testScrew the pedal-spindle securely into a suitable rigid fixture with its axis horizontal, as shown in Figure 43, andapply a vertically-downward force of 1 500 N for 1 min to the centre of the pedal as shown in Figure 41. Releasethe force and examine the pedal assembly and the spindle.4.13.4 Pedal-spindle – impact test4.13.4.1 RequirementWhen tested by the method described in 4.13.4.2, the spindle shall not fracture and any permanent bending shallnot exceed 15 mm at the point of impact.NOTEVisible cracking is permissible because of the hardened surface.4.13.4.2 Test methodScrew the pedal-spindle securely into a suitable rigid fixture with its axis horizontal as shown in Figure 44 andrelease a striker of the design shown in Figure 44 and weighing 15 kg from a height of 400 mm strike the spindle ata point 60 mm from the mounting-face of the rigid fixture or 5 mm from the end of the spindle if the spindle isshorter than 65 mm.68

If the pedals are provided withtwo tread surfaces, rotate them through 180° after 50 000 revolutions.69
