IS 9315 : 2024/ISO 5355 : 2019 Alpine Ski-Boots - Requirements and Methods of Test
NATIONAL FOREWORD
This Indian Standard (First Revision) which is identical with ISO 5355 : 2019 'Alpine ski-boots - Requirements and test methods' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Mountaineering Sectional Committee and approval of the Production and General Engineering Division Council.
Unlike regular ski boots, alpine touring (AT) boots are designed for both downhill skiing and uphill travel. AT boots typically have a rigid, supportive ski mode, with a "walk" mode that unlocks the spine of the boot to let your ankle and lower leg flex forward and back for walking uphill.
This standard was first published in 1979. This first revision has been undertaken to align it with the latest version of ISO 5355 : 2019.
The major changes in this revision are as follows:
a) Definition of material properties of Polytetrafluoroethylene (PTFE) to test the dynamic friction of boot materials has been added;
b) Information to be supplied by the manufacturer has been added; and
c) Tolerance for sole length has been added.
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are however not identical to those used in Indian Standards. Attention is particularly drawn to the following
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current-practice is to use a point (.) as the decimal marker.
