This document 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.<\/p>\n
This document applies to cross-country skis with a nominal length greater than or equal to 150 cm.<\/p>\n
The standard measurement procedures can be used to ensure comparability between laboratory measurement data, determined and published by ski manufacturers, institutions or others.<\/p>\n
In this document, no attempt is made to relate the measurement data to the quality of the ski.<\/p>\n
