This document specifies a method for the determination of the fatigue indexes of cross-country skis (i.e. the resistance of the skis to changes of bottom camber height or irreversible damage) after a bending test with cyclic loading. It is applicable to cross-country skis with a nominal length of 160 cm to 215 cm.
