ISO 6005 pdf download – Alpine skis一Ski binding screws一Test methods.
5 Procedure
5.1 Determination of the breaking moment Test method in accordance with 150 3506
5.2 DuctilIty test
Drive the crrew to be tested into an assembly specified In 4.1.
Using a hammer, strike the edge of the screw head with several laleral blows until a deformation of 10 is obtained.
NOTE 1 This method is not a suitable control trw hydrogen embrittlement, for which a test method will be this iihj.r’t nI hit.ir. International ctandard.
5.3 Determination of the driving torque
5.3.1 Using the drill lg, drill a hole of diameter 405.
4,1 H12 ( mm) and depth (9 ; mm in test assembly M. The hole shall not he tapped
5,3.2 Drive the screw to be tested into the hole, using the test jig and a suitable torque wrench screwdriver. Read the driving torque afler each halt rotation. No lubrication shall be used during this procedure and the maximum penetration without contact of the screw head and the distance plate shall be 8 mm -I- 0,2 mm.
S3 Record the maximum driving torque, In newton metres, as the largest measured value of the torque applied during the driving procedure.
5.3.4 Repeat the test, using at least ten screws.
5.4 DeterminatIon of the stripping torque
5.4.1 Using the drill jig, drill a hole of diameter
4.1 H12and depth (7 5) mm in test assembly P The hole shall not h tappr1
5.4.2 Use the test jig to mount and tighten the screws. Apply an increasing torque with the toique wrench screwdriver until a drop in the torque resistance indicates failure or the thread The maximum penetration depth shall be 6 mm ± 0.2 mm
5.4.3 Record the stripping torque, in newton metros, as the maximum value of the moment read on the torque wrench screwdriver.
5.4.4 Repeat the test, using at least ten screws,
5.5 Static pull-out test
5.5.1 Usina the drill jig, drill holes of diameter
4.1 H12and depth (9 0 J mm in test assembly P. ensuring that the holes are at least 50 mm apart
5.5.2 Use the pull-out apparatus rlesrrthed in 4.4 (see figure4). which allows the Introduction of the screw perpendicular to the surface of the test assembly to a penetration depth of 8 mm ± 0,5 mm, and an axial load of the screw perpendicular to the surface of the test assembly during the pull-out test
Use a maximum tightening torque of 4 N-rn
Position the test assembly such that the test screw is equidistant from the support rolls.
5.5.3 Apply a load at a rate of 20 mm/mm until the screw is pulled from the test assembly Record the maximum load required.
