3.1 interface part of the ski-boot intended to contact with the ski-binding
3.2 front interface part of the ski-boot intended to contact with the front binding
3.3 rear interface part of the ski-boot intended to contact with the rear binding
3.4 free space space intended to avoid contact between ski-boot and binding, especially during step in/step out or release
3.5 median plane middle plane of the sole, longitudinal and perpendicular to the bearing surface
3.6 bearing surfaces front and rear surfaces of the boot sole which are in contact with a plane on which the boot is standing
3.7 ski-brake device to stop the ski after release of the binding
4 Requirements and test methods
4.1 General
If no specific test methods are indicated, check the characteristics as appropriate, e.g. by measurement. If not otherwise indicated, execute the testing under standard atmosphere 23/50 (see ISO 554) with ordinary tolerances.
4.2 Dimensions 4.2.1 Requirements The boot toe and heel shall comply with Figures 1 and 2. Other boot dimensions need not correspond to the figures. Fundamentally, all dimensions shall be within the indicated tolerances. However, relevance to safety varies in importance depending on the indicated dimensions. Looking at several dimensions (“ dimensions of the 2nd degree”]) deviations may be accepted, provided that the following requirements are respected.
a) The deviations shall remain exceptional. b) The deviations are small. c) No limitations of function arise with all marketable and critical bindings. d) The tolerances are respected at the next possible opportunity (e.g reconstruction of a tool). See Annex B.
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 — typeA:100N; — typeC:50N by inserting into the ski-boot itself a steel cylinder with a diameter of
— type A: 80 mm; — typeC:5Ornm the ends rounded with a 10 mm radius and having a corresponding mass. After 5 mm, determine the flatness measurement as follows. When the boot rests on the test plane (see 1igure 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.ISO 5355 pdf download.
