ISO 7139-2017 越野滑雪板--彈性性能的測定 Cross-country skis — Determination of elastic properties

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.
This document applies to cross-country skis with a nominal length greater than or equal to 150 cm.
The standard measurement procedures can be used to ensure comparability between laboratory measurement data, determined and published by ski manufacturers, institutions or others. In this document, no attempt is made to relate the measurement data to the quality of the ski.nd edition 2017-11 Cross-country skis — Determination of elastic properties Skis de fond — Détermination des caractéristiques élastiques Reference number ISO 7139:2017(E) ？ ISO 2017 ISO 7139:2017(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2017, Published in Switzerland All rights reserved.
