This International Standard specifies laboratory measurement methods to determine the elastic properties of cross-country skis. Its purpose is to calculate the resistance of defined parts of the ski to bending. This International Standard applies to cross-country skis with a nominal length greater than or equal to 150 cm. The standard measurement procedures are recommended in order to ensure comparability between laboratory measurement data, determined and published by ski manufacturers, institutions or others. In this International Standard no attempt is made to relate the measurement data to the quality of the ski.
