The other current International Standards are ISO 8061 and ISO 9462.National standards, complying with legal regulations, may be more extensive, for instance c

15、overing combined loading and ski deflection. International Standards are being prepared that address these aspects. To verify the safety of ski-bindings, it is necessary to use all International Standards of the series and additionally the national standards covering those aspects which are not yet

16、standardized internationally.The release and retention functions of ski-bindings are multifaceted and complex. The functions involve combinations of static and dynamic loading in varied release directions of the boot relative to the ski. This impulsive test method evaluates an important ski-binding

17、function, but it should not be interpreted as conclusively evaluating the binding impulse release behaviour in general. The test evaluates the release and retention function of the binding in a single mode of binding release; other static and dynamic retention and release tests are not excluded by t

18、his standard test.Alpine ski-bindings Lateral release under impact loading Test methodDIN ISO 9465:2013-05 5 1 ScopeThis International Standard defines an impact test for establishing the maximum impulse for retention of a test ski on the test sole in the lateral direction.The test provides a measur

19、e of the release/retention boundary for lateral release of a ski-binding for adults (type A according to ISO 9462) at a particular ski-binding setting.The test method is designed to simulate the lateral impulsive loading during skiing located at the front part of the ski. The test permits the evalua

20、tion of a ski-bindings release and retention properties under expected loading rates. The test permits comparison of the release caused by lateral impulse to the ski for different binding system designs.2 Normative referencesThe following referenced documents are indispensable for the application of

The ski release binding is adjusted for a static release in accordance with ISO 9462:, 6.4. The release setting is recorded.The test ski is mounted on the test so

32、le. The sole is rigidly fixed during testing.The contact material between the test ski and the pendulum impact is as specified in 4.2.7.The standard pendulum applies impulsive loading to the test ski at the lowest point of the pendulum arc.The pendulum pivot friction and the contact material are eva

33、luated according to 4.2.6.2 and 4.2.7.3 prior to and following the test of ski release bindings. Records of the evaluations are maintained.The pendulum release angle is decreased from a value sufficient to guarantee release of the binding following a single impact of the test ski until the maximum a

34、ngle for which retention of the binding is obtained. The release angle causing the ski-binding to release at the release/retention boundary is recorded.DIN ISO 9465:2013-05 84.2 Apparatus4.2.1 Test skiThe test ski is a U-shaped channel section of aluminium with the following dimensions (see Table 1)

35、:Table 1 Dimensions of the test skiDimensions in millimetresUSA size European sizeLength 500 2 500 2Width 62 2 60Height 35 5 40Wall thickness 3,6 0,6 3The toe of the boot sole shall be located (75 1) mm from the tip of the test ski. The binding being tested can either be mounted directly on the test

36、 ski or on an original ski piece (ski interface), which then couples with the test ski. The total mass of the test ski and the ski interface shall not exceed 1 200 g without the binding, and the length of the ski interface shall be within (700 10) mm.4.2.2 Test soleThe test sole shall conform to ISO

37、 9838 except when the binding manufacturer specifies modifications for the sole design. The test sole is backed by a steel plate (216 4) mm (57 3) mm (10 1) mm. The test sole is bolted to the plate which is used for rigidly holding the test sole to the support.4.2.3 Pendulum tower4.2.3.1 The pendulu

38、m tower shall be sufficiently rigid that it does not influence the impact response of the test ski.4.2.3.2 One configuration for the tower consists of a structure of four steel plates welded into the form of a hollow, square cylinder with external square cross-section dimensions (254 2) mm (254 2) m

39、m and length (1 220 2) mm. The plate thickness is (9,5 0,5) mm. An additional steel plate of dimensions (330 2) mm (330 2) mm (25 1) mm is welded to the bottom of the cylinder, and a plate of dimensions (305 2) mm (381 2) mm (13 0,5) mm is welded to the top. The latter two plate surfaces are approxi

40、mately parallel and perpendicular to the long axis of the cylinder. The base plate is drilled to allow the tower to be bolted rigidly to a concrete foundation in four or more places. The top plate forms a nearly rigid foundation for the pendulum bearing system.4.2.3.3 The pendulum bearing base shall

41、 allow adjustment of the pendulum height and position by movement of the pendulum bearing in the plane of the pendulum motion. Height adjustment is required in order to guarantee proper impact of the contact tip with the impact location for bindings of different heights. Adjustment of the horizontal

42、 position is required in order to guarantee that impact occurs at the bottom of the pendulum arc.4.2.4 Pendulum shaft4.2.4.1 The pendulum shaft is a circular steel cylinder of mass (2,3 0,1) kg. The shaft is (1 000 2) mm long with an outer diameter of (40 0,1) mm and an inner diameter of (35 0,1) mm

43、. The shaft is mounted in the pendulum bearing so that it swings in a single vertical plane normal to the test ski.4.2.4.2 The pendulum shaft is rigidly secured to the pendulum block on the end of the shaft furthest from the pendulum bearing. The pendulum block mass is (3 0,1) kg. The contact tip ha

44、s a hardness of 45 HRC and a diameter of (10 0,5) mm and is rigidly fixed to the pendulum block.DIN ISO 9465:2013-05 9 4.2.4.3 The length from the centre of the pendulum bearing to the point of impact on the contact tip is (1 025 5) mm.4.2.5 Test sole support4.2.5.1 The test sole support holds the t

45、est sole rigidly.4.2.5.2 The support structure is constructed of heavy steel plate and is mounted in a concrete foundation in order to maintain rigidity during impact.4.2.5.3 The support adjustment allows movement of the test sole longitudinally for positioning the impact location relative to the co

46、ntact tip.4.2.6 Pendulum bearing4.2.6.1 A roller bearing with an inner diameter of at least (12 0,5) mm supports the pendulum shaft on the pendulum tower.4.2.6.2 The pendulum bearing function is evaluated by a free oscillation test of the complete pendulum tower, shaft and block systems. No test ski

47、 or boot is involved. The pendulum is released from rest at a pendulum release angle of (12 0,5). The pendulum shall move through at least 60 complete oscillations before coming to rest at the vertical equilibrium. The number of oscillations is recorded.4.2.7 Contact material specification4.2.7.1 Th

48、e contact material is chosen to produce a loading separation time from 20 ms to 100 ms at the toe of the test sole, which is similar to those measured during skiing.4.2.7.2 The contact material shall be neoprene with shore A hardness from 60 to 65 and dimensions of (20 0,2) mm (20 0,2) mm (7 1) mm at 23 C. Contact materials constructed of metal, wood, acrylic plastic and other hard materials are specifically excluded, as well as contact materials from very soft materials that give long loading durations or larg
