Figure 46 — Crank assembly – fatigue test with cranks at 45° (typical test arrangement)
4.13.7.4 Test method with the cranks at 30° to the horizontal
Mount the assembly of the two pedal-spindles (with extension adaptors if necessary), the two cranks, the chainwheel
cluster (or other drive component), and the bottom-bracket spindle located on its normal-production bearings
in a fixture with bearing-housings representative of the bottom-bracket, as shown in Figure 47. Incline the cranks at
30° to the horizontal as shown in Figure 47. Restrain the left-hand crank to the base of the test machine by a
device attached to the pedal-spindle at a distance of 65 mm from the outboard face of the crank.
Apply a repeated, vertically-downward, dynamic force of 1 800 N to the pedal-spindle of the right-hand crank at a
distance of 65 mm from the outboard face of the crank (as shown in Figure 47) for 50 000 cycles.
The maximum test frequency shall be 25 Hz.
