Significance and Use4.1 Results obtained by this test method can

18、 be used todetermine the suitability of specific test device designs inmeasuring the release moments of ski/boot/binding systems.4.2 This test method provides a means by which manufac-turers of test devices and manufacturers of releasable skibindings can provide compatible instructions to facilities

19、 whichperform the final inspection of the complete boot/binding/skisystem prior to use.4.3 This test method is not appropriate for determiningprecision between operators.5. Apparatus5.1 Test SkiThe test ski shall meet the stiff ski definition inthe portion of the Apparatus Section of Test Method F50

20、4pertaining to skis and bindings.5.2 Test SoleThe test sole shall meet the requirements inthe portion of the Apparatus Section of Test Method F504pertaining to boots, and shall be of a design compatible withthe reference binding. The test sole may be modified toestablish necessary interfaces with th

21、e standard apparatus andtest device providing such modifications do not influence theproper function of the reference binding.5.3 Test Frame and Instrumentation:5.3.1 All apparatus shall meet the portions of the ApparatusSection of Test Method F504 pertaining to cable,instrumentation, and load appli

22、cation.5.3.2 Devices shall be employed to monitor cable tension.Differences of more than 5 % in cable tension at the attachmentpoints with the ski may significantly bias results.5.4 Reference BindingThe reference binding shall be ofthe type specified by the manufacturer of the test device.6. Prepara
