Scope1.1 This test method defines procedures to determine agree-ment between a standard apparatus for measuring the releasemoments of s
3、ki bindings and a test device of unspecifieddesign.1.2 This test method also covers procedures for checkingagreement between individual devices of identical but unspeci-fied design, intended for determining the release moments ofski bindings.1.3 Values expressed in newton meters, newtons, and cen-ti
4、meters are to be regarded as the standard.1.4 Values expressed in units of torque may be converted tothe appropriate force values when devices which indicate forceare used.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibilit
5、y of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.
