ISO 6005:1991 pdf download.Alpine skis 一Ski binding screws - Test methods
I Scope
ISO 6005:1991 pdf download specifies test methods for screws used for fastening ski bindings to alpine skis.
Acceptance criteria are specified in ISO 6004.
The results of these test methods characterize only thc properties of the binding screw and give no information about the actual mounting and fastening characteristics of different ski models. A test method for these characteristics is specified In ISO 8304.

4.1 Fixation for ductility test
The assembly shall be made in a manner which does not damage the screw threads; at least two complele Ihreads shall overlop the assembly.
4.2 Test assembly
For the purpose of this test, it is necessary to pre-pare test assemblies representative of material configurations commonly used in ski construction and having dimensions similar to those of a cross-section of the binding mounting area of an alpine ski.
4.3 Drill and test jig
A jig, as shown in figure 2, shall be used for drilling the holes and also for determining the driving torque and the stripping torque. The j)ig shall ensure an exact drill hole of diameter 4,1 mm, perpendicular to the top surface of the test assembly, and a mini-mum distance of 50 mm between the holes. It shall also ensure that the test screw is set and mounted perpendicular to the top surface of the test as-sembly.
For each test, a new location of the test jig shall be used.
The drill jig bushing shall be made from hardened steel and shall be fixed against rotation. The friction plate shall be made from steel of hardness 135 (HB 30; see ISO 6506) and shall have a surface roughness of 0,8 μm (see IsO 2632-1). The centering pins shall be used to hold the friction plate in place.
For determination of the driving torque and stripping torque, a friction plate (see figures 2 and 3), with a thickness in accordance with the penetration depth needed, shall be used.ISO 6005 pdf download.
