Significance and Use4.1 Results obtained by this test method can be used todetermine the suitability of specific test d

16、evice 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 whichperform the final inspection of the complete boot

17、/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 definitionin the portion of the Apparatus Section of Test Method F 504pertaining to skis and bindings.5.2 Test SoleThe test

18、 sole shall meet the requirements inthe portion of the Apparatus Section of Test Method F 504pertaining to boots, and shall be of a design compatible withthe reference binding. The test sole may be modified toestablish necessary interfaces with the standard apparatus andtest device providing such mo

19、difications 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 F 504 pertaining to cable, instrumen-tation, and load application.5.3.2 Devices shall be employed to monitor

20、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. Preparation of Apparatus6.1 Mount the reference binding o

21、n the test ski and fit to thetest sole in accordance with the specification of the bindingmanufacturer.6.2 Lubricate all interfaces within the reference binding andall areas of sliding contact between test sole and binding witha compatible grease.6.3 Calibrate the binding in tests 1.1 and 2.1 (and 2

22、.2 ifappropriate) of Test Method F 504, using the standard appara-tus.6.3.1 The calibration of the reference binding shall be asspecified by the test device manufacturer.NOTE 1Methods E4 and E74 may be used as general guides indeveloping calibration procedures.6.4 Condition the binding prior to each
