Introduction of ISO 8601:
This International Standard is one of a series of International Standards dealing with the safety of ski-bindings; the other International Standards in this series are ISO 9462:1993, Alpine ski-bindings — Safety requirements and test methods and ISO 9465:1991, Alpine ski-bindings — Lateral release under impact loading — Test method.
National standards, complying with legal regulations, may be more extensive, for example regarding
— combined loading, and/or
— deflexion of the ski.
International Standards covering these aspects are being prepared.
To verify the safety of ski-bindings, it is necessary to use all three International Standards of the series and also national standards covering aspects which are not yet standardized internationally.
In recommending the release torques, it is necessary to take into account the abilities of the skier concerned by applying skier-type correction factors. For this purpose, three types of skier are defined, as described in Annex A.
This International Standard specifies methods for the selection of the release torques for alpine ski-bindings in current use, and gives information necessary to determine the release torques.
It applies to torque-measuring binding-test machines.
It may be inappropriate for non-mechanical bindings or bindings used with boots which reach more than halfway up the lower leg.
NOTE Manufacturers may use either of the two specified methods as the basis for their recommended release torques.
Release torques are to be recommended for use by ski-binding manufacturers in their instructions for installation and use, and by ski shops for the adjustment of already mounted ski-bindings.
A.1 Skier types
A.1 .1 It is the responsibility of the skier to determine his/her skier-type classification as defined in Table A.1.
A.1 .2 Skiers are classified by type of skiing into three types, 1, 2 and 3. The definitions are as follows:
— Type 1: cautious skiing on smooth slopes of gentle to moderate pitch. This type also applies to entry-level skiers uncertain of their classification. Skiers who designate themselves as type 1 receive lower than average release/retention settings. This corresponds to an increased risk of inadvertent binding release, in order to gain increased capacity for release in a fall.
— Type 2: skiers not classified in type 1 or 3.
— Type 3: fast, aggressive skiing on slopes of moderate to steep pitch. Skiers who designate themselves as type 3 receive higher than average release/retention settings. This corresponds to decreased capacity for release in a fall, in order to gain a decreased risk of inadvertent binding release.
Designations 1, 2 and 3 should not be used by equipment manufacturers to categorize their products.
A.1 .3 The information given in Table A.1 is an example of the kind of layout which may be used to assist the skier in determining his skier-type classification.ISO 8601:2004 pdf free download.
