BS ISO 5355-2019 pdf free download.Alpine ski-boots — Requirements and test methods.
This document specifies the requirements, test methods and marking of ski-boots which are used with current systems of alpine ski-bindings with attachment at the boot toe and boot heel, the proper release function of which depends on the dimensions and design of the interfaces.
For ski-binding systems that function irrespective of the sole shape or that have different requirements for the sole dimensions, it is not always necessary for the ski-boot soles to comply with this document in order to achieve the desired degree of safety.
It applies to ski-boots of sizes 15,0 and larger [types A (for adults) and C (for children)] in the Mondopoint system (see Annex A).

3.1 interface

4.2.2 Testing of evenness
4.2.2.1 When the front bearing surface rests on a plane, a gauge 1 mm thick and 10 mm wide shall not enter the AB area at any point. See Figure 3.
4.2.2.2 When the rear bearing surface rests on a plane, a gauge 1 mm thick and 10 mm wide shall not
enter the CD area at any point. See Figure 4.
4.2.2.3 Before measuring the evenness of the bearing surfaces as described in Figure 5, apply a load of
— type A: 100 N;
— type C: 50 N
by inserting into the ski-boot itself a steel cylinder with a diameter of
— type A: 80 mm;
— type C: 50 mm
the ends rounded with a 10 mm radius and having a corresponding mass. After 5 min, determine the flatness measurement as follows.
When the boot rests on the test plane (see Figure 5), check the maximum thickness of a 10 mm wide gauge which can enter the BC area anywhere (to a maximum of 2 mm). This gauge shall not enter the AB and CD areas.
4.3 Design
4.3.1 Sole length
The sole lengths of the two ski-boots in a pair shall not differ by more than 2 mm.
4.3.2 Symmetry
The sole dimensions in the toe and heel interface areas shall be symmetrical about the median plane within an admissible deviation of 1 mm.
4.3.3 Side walls at boot toe
The side walls of the sole at the boot toe, up to a distance of at least 25 mm from the toe end, shall be perpendicular to the bearing surface within an admissible inward-outward deviation of 1 mm.
If the side walls of the sole are built in two parts, it shall be ensured that no part of the lower area of the sole protrudes beyond the upper profile.BS ISO 5355 pdf download.
