ISO 6005:1991 pdf download – Alpine skis – Ski binding screws – Test methods
1 Scope
This International Standard 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 the 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 8364.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publi- cation, the editions indicated were valid. All stan- dards are subject to revision， and parties to agreements based on this International Standard are encouraged to investigate the possibility of ap- plying the most recent editions of the standards in- dicated below. Members of IEC and ISO maintain registers of currently valid International Standards.
4.3 Drill and test jig
A jig as shown in figure 2, shall be used for driling the holes and also for determining the driving torque and the stripping torque. The jig 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 jlg bushing shall be made from hardened steel and shall be fixed against rotation. The friction plate shall be made from stcel of hardness 135 (HB 30; see ISO 6506) and shall have a surface roughness of 0,8 um (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.
4.4 Pull-out apparatus (see figure 4)
Two rolls, of diameter 30 mm and 250 mm apart, shall be used to support the test assembly together with an attachment plate (see figure 4) which per- mits penetration by the test screw to a depth of 8,5 mm in the test assembly (see also ISO 8364).
5.2 Ductility test Drive the screw to be tested into. an assembly specified in 4.1. Using a hammer, strike the edge of the screw head with several lateral blows until a deformation of 10° is obtained. NOTE 1 This method is not a suitable control for hy- drogen embrittlement, for which a test method will be the subject of a future Intern ational Standard.
