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.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.Before measuring the evenness of the bearing surfaces as described in Figure 5, apply a load of type A: 100 N; typeC:50N by inserting into the ski-boot itself a steel cylinder with a diameter of type A: 80 mm; typeC:50mm 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.The sole lengths of the two ski-boots in a pair shall not differ by more than 2 mm. The sole dimensions in the toe and heel interface areas shall be symmetrical about the median plane within an admissible deviation of 1 mm. 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. The lateral side walls of the sole at the boot heel, up to a distance of at least type A: 70 mm; typeC:50mm.from the heel end, shall be perpendicular to the bearing surface, or tapered inwards 一outwards between 0° and 10° up to a height of 14 mm. No part of the sole shall project beyond the 10° side wall limitation up to a height of 14 mm, between typeA:70mmand85mm; typeC:50mmand65mm. If lateral grooves of more than 2 mm depth are present at the heel, see Figure 6, supports at least complying with Figure 7 shall remain. Other configurations of grooves are allowed if they are within the given dimensions in Figure 6 and Figure 7.BS ISO 5355 pdf download.
