11、ization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been establish

12、ed has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

23、 devices Requirements and test methods 3 T erms a nd definiti ons For the purposes of this document, the following terms and definitions apply. 3.1 alpine ski-binding system to ensure firm connection between boot and ski, fixing the heel low for downhill skiing Note 1 to entry: The system releases t

24、he boot from the ski when certain loads reach preset values. 3.2 release detachment of the boot from the ski by release of the mechanism that ensures the connection between boot and ski Note 1 to entry: This release is only considered effective when all the loads due to the boot/ski connection have

25、dropped to values which present no danger to the skier. 3.3 release values maximum values of torques M zand M ycaused at the boot/ski connection by the two movements of torsion and forward bending Note 1 to entry: For the torques M zand M y , see Figure 1. Note 2 to entry: These values are generally

26、 adjustable on current bindings which have a scale and an indicator displaying the setting level. Note 3 to entry: In the present state of the art, bindings are designed at least to release in torsion (M z ) and in forward bending (M y ).

28、 time, where one of the loads is the torque M zprogressively applied to the sole until the binding releases Note 1 to entry: Each of the load combinations simulates a given situation, chosen within an infinite field of possibilities and simplified for the purpose of the tests. The main simplificatio

29、n being that the loads applied additionally to the release torque M zare held constant in value and direction during all the release process.

30、o f t h e sk i deflection of the ski perpendicular to its gliding surface Note 1 to entry: In practice, the deflection of the ski depends at the same time on the loading situation and the profile of the snow-surface (“geometrical” situation). In test simplification, only the “geometrical” situation

36、 be smaller than 2 % for values above 50 Nm inclusive and 1 Nm for values below 50 Nm. The measurement error of the release value in forward bending shall be smaller than 2 % for values above 200 Nm inclusive and 4 Nm for values below 200 Nm. The test equipment shall be designed to allow application

37、 of pure moments without any extraneous forces during the entire release process. 4.3 Test sole The test sole shall be in accordance with ISO 9838. If a boot-binding system requires a specific boot-sole design, a test sole should be cut from a boot provided by the manufacturer and adapted for test n

38、eeds. The test sole shall be degreased, washed, and dried before testing. 4.4 Test ski For the release tests in the laboratory, the bindings shall be mounted either on whole skis or on appropriate sections of skis. If the binding is pre-mounted (already mounted on the ski by the producer), use the s

39、ki with which the binding is delivered in its medium size. If not, choose a ski which represents the market. 5 Test methods A and B 5.1 Principle The binding shall be mounted on a ski in accordance with the manufacturers instructions. A test sole shall then be inserted in the binding. In method A, t

40、he ski is rigidly connected to the test frame and the torque M zor M yis progressively applied to the sole until the binding releases. The peak value of M zor M yis recorded. In method B, the sole is rigidly connected to the test frame through a sensor which measures the torques M zand M y . Forces

41、are progressively applied to the ski until the binding releases. The peak value of M zor M yis recorded. Annexes A and B give examples of how to realize method A or method B. Passing by either method shall be deemed satisfactory. 5.2 Simple torsion test For method A, see Figure 2.4 ISO 2014 All righ

45、a torque M zabout an axis perpendicular to the ski gliding surface, and when applying a torque M yabout an axis parallel to the ski surface and perpendicular to the longitudinal axis of the ski. The binding is said to release when the mentioned torque reaches a maximum value (release value) and then

46、 drops to a value that is harmless for the skier. After release, all the loads applied by the ski and the boot on the leg shall remain under the dangerous level for all possible movements, and until all the risks associated with the coupling boot-ski have disappeared. 6.1.1.2 The release level shall

47、 be clearly indicated by a scale covering all of the setting range anticipated by the manufacturer. The release shall still be possible at the upper limit (maximum setting). Settings above Z = 10 shall be clearly differentiated from settings below Z = 10 on the indicator scale. 6.1.1.3 Each procedur

48、e of adjustment to the boot having an influence on the binding functioning shall be verifiable by the use of a clear indicator, or by any other means considered suitable by the operator for showing the correct adjustment. 6.1.1.4 The binding shall be equipped with a ski-brake or allow for an easy an

49、d secure attachment of a leash. The ski-brake and the attachment for the leash shall be according to ISO 11087. ISO 2014 All rights reserved 7BS ISO 9462:2014ISO 9462:2014(E) 6.1.1.5 The design of the ski-brake or the leash shall be such that, after release, no unnecessary danger will occur to the skier. 6.1.1.6 The binding shall have an external design which does not have a negative influence on skiing or cause unnecessary risk of injuries when used normally. 6.1.2 Ha
