Alpine ski-bindings - Lateral release under impact loading - Test method

This International Standard defines an impact test for establishing the maximum impulse for retention of a test ski on the test sole in the lateral direction. The test provides a measure of the release/retention boundary for lateral release of a ski-binding for adults (type A according to ISO 9462) at a particular ski-binding setting. The test method is designed to simulate the lateral impulsive loading during skiing located at the front part of the ski. The test permits the evaluation of a ski-binding's release and retention properties under expected loading rates. The test permits comparison of the release caused by lateral impulse to the ski for different binding system designs.

Fixations de skis alpins — Déclenchement latéral sous choc — Méthode d'essai

La présente Norme internationale définit un essai de choc en vue d'établir le choc latéral maximal sous lequel un ski d'essai reste solidaire de la semelle d'essai. L'essai fournit une mesure de la limite entre déclenchement et retenue pour le déclenchement latéral d'une fixation de ski pour adultes (type A selon l'ISO 9462) pour un réglage donné de cette fixation. La méthode d'essai est conçue pour simuler les charges de choc latérales survenant en skiant sur la partie avant du ski. Cet essai permet d'évaluer les propriétés de déclenchement et de retenue d'une fixation de ski dans des conditions de charges attendues. Cet essai permet également de comparer le déclenchement latéral causé par un choc latéral sur le ski pour des systèmes de fixation de conception différente.

Varnostne vezi za alpske smuči - Bočno odpiranje pri udarni obremenitvi - Preskusna metoda

Ta mednarodni standard določa udarni preskus za določanje največjega impulza za zadržanje preskusne smuči na preskusnem podplatu v bočni smeri. Preskus zagotavlja merilo za mejo odpiranja/zadržanja pri bočnem odpiranju vezi za smuči za odrasle (tip A glede na standard ISO 9462) pri posamezni namestitvi vezi za smuči. Preskusna metoda simulira bočno udarno obremenitev med smučanjem na sprednjem delu smuči. Preskus omogoča določanje lastnosti odpiranja in zadržanja pod pričakovanimi obremenitvami. Preskus omogoča primerjavo odpiranja, ki ga povzroči bočni impulz na smuči, za različne vrste veznih sistemov.

Overview

ISO 9465:2012 - "Alpine ski‑bindings - Lateral release under impact loading - Test method" specifies a controlled impact test to determine the maximum impulse that a ski‑binding will retain a test ski on a test sole in the lateral (sideways) direction. The procedure simulates lateral impulsive loads applied near the front of the ski and defines a reproducible release/retention boundary for adult (Type A) bindings at a given setting. This standard supports objective comparison of binding designs and evaluation of release behaviour under realistic loading rates.

Key topics and technical requirements

• Test principle: A pendulum strikes the side wall of a U‑shaped aluminium test ski, producing a lateral impulse; the pendulum release angle is decreased to identify the limit between release and retention.
• Test components:
  • Test ski: aluminium U‑channel with specified dimensions and mass limits.
  • Test sole: ISO 9838 test sole backed by a steel plate, rigidly fixed.
  • Pendulum: defined shaft and block masses, contact tip (10 mm diameter, 45 HRC), and an impact radius (~1 025 mm).
  • Contact material: neoprene (shore A 60–65), nominally 20 × 20 × 7 mm, positioned ~10 mm from the ski tip to produce realistic loading durations (20–100 ms).
• Instrumentation & measurements:
  • Goniometer to measure pendulum release and rebound angles (accuracy ±0.5°).
  • Pendulum bearing qualification via free oscillation (minimum oscillations specified).
  • Contact material qualified by percentage rebound R (average between 34% and 39% for specified test angle).
• Procedure & reporting: Static settings per ISO 9462 are recorded; three borderline release tests are reported along with equipment, temperature, quasi‑static release moments, and qualification data.

Applications and users

ISO 9465:2012 is used by:

• Ski‑binding manufacturers - product development, design verification and performance comparison.
• Test laboratories and certification bodies - conformity testing and quality control for lateral impulse release characteristics.
• R&D and safety engineers - investigating release/retention behaviour under impulsive lateral loads and optimizing binding release algorithms.
• Standards committees and regulators - harmonizing test methods and supporting national standards and safety regulations.

Practical uses include validating binding settings, comparing system designs, documenting performance for technical files, and supporting consumer safety claims.

Related standards

• ISO 9462 - Alpine ski‑bindings: requirements and test methods (static settings and energy absorption).
• ISO 9838 - Alpine and touring ski‑bindings: test soles for ski‑binding tests.

Foreword
ISO (the International Organization 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
established 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an

Introduction
This International Standard is one of a series dealing with the safety of ski-bindings. The other current
International Standards are ISO 8061 and ISO 9462.
National standards, complying with legal regulations, may be more extensive, for instance covering combined
loading and ski deflection. International Standards are being prepared that address these aspects. To verify
the safety of ski-bindings, it is necessary to use all International Standards of the series and additionally the
national standards covering those aspects which are not yet standardized internationally.
The release and retention functions of ski-bindings are multifaceted and complex. The functions involve
combinations of static and dynamic loading in varied release directions of the boot relative to the ski.
This impulsive test method evaluates an important ski-binding function, but it should not be interpreted as
conclusively evaluating the binding impulse release behaviour in general. The test evaluates the release and
retention function of the binding in a single mode of binding release; other static and dynamic retention and
release tests are not excluded by this standard test.

4 Test method
4.1 Principle
The ski-binding is mounted on a standard test ski. The ski release binding is adjusted for a static release in
accordance with ISO 9462:—, 6.4. The release setting is recorded.
The test ski is mounted on the test sole. The sole is rigidly fixed during testing.
The contact material between the test ski and the pendulum impact is as specified in 4.2.7.
The standard pendulum applies impulsive loading to the test ski at the lowest point of the pendulum arc.
The pendulum pivot friction and the contact material are evaluated according to 4.2.6.2 and 4.2.7.3 prior to and
following the test of ski release bindings. Records of the evaluations are maintained.
The pendulum release angle is decreased from a value sufficient to guarantee release of the binding following
a single impact of the test ski until the maximum angle for which retention of the binding is obtained. The
release angle causing the ski-binding to release at the release/retention boundary is recorded.
4.2 Apparatus
4.2.1 Test ski
The test ski is a U-shaped channel section of aluminium with the following dimensions (see Table 1):

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes nationaux de
normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est en général confiée aux
comités techniques de l’ISO. Chaque comité membre intéressé par une étude a le droit de faire partie du comité
technique créé à cet effet. Les organisations internationales, gouvernementales et non gouvernementales,
en liaison avec l’ISO participent également aux travaux. L’ISO collabore étroitement avec la Commission
électrotechnique internationale (CEI) en ce qui concerne la normalisation électrotechnique.
Les Normes internationales sont rédigées conformément aux règles données dans les Directives ISO/CEI, Partie 2.
La tâche principale des comités techniques est d’élaborer les Normes internationales. Les projets de Normes
internationales adoptés par les comités techniques sont soumis aux comités membres pour vote. Leur publication
comme Normes internationales requiert l’approbation de 75 % au moins des comités membres votants.
L’attention est appelée sur le fait que certains des éléments du présent document peuvent faire l’objet de droits
de propriété intellectuelle ou de droits analogues. L’ISO ne saurait être tenue pour responsable de ne pas avoir
identifié de tels droits de propriété et averti de leur existence.
L’ISO 9465 a été élaborée par le comité technique ISO/TC 83, Matériels de sports et d’activités de plein air,
sous-comité SC 4, Équipements de sport de neige.
Cette deuxième édition annule et remplace la première édition (ISO 9465:1991), qui a fait l’objet d’une
révision technique.
Introduction
La présente Norme internationale fait partie d’une série de normes traitant de la sécurité des fixations de ski.
Les autres Normes internationales sont, à ce jour, l’ISO 8061 et l’ISO 9462.
Les normes nationales conformes à des réglementations peuvent être plus complètes, par exemple en ce
qui concerne les charges combinées et la flexion du ski. Des Normes internationales sont en cours d’étude
sur ces aspects. Pour vérifier la sécurité d’une fixation de ski, il est nécessaire d’utiliser toutes les Normes
internationales de la série et, en outre, les normes nationales couvrant les aspects qui ne sont pas encore pris
en compte au point de vue international.
Les fonctions de déclenchement et de retenue des fixations de ski sont multiples et complexes. Ces fonctions
impliquent des combinaisons de charges statiques et dynamiques dans les différentes directions de libération
de la chaussure par rapport au ski. La présente méthode d’essai par choc évalue une importante fonction de
la fixation de ski mais il convient de ne pas la considérer comme une évaluation définitive du comportement
de déclenchement sous choc de la fixation en général. Cet essai évalue la fonction de déclenchement et de
retenue des fixations pour un seul mode de déclenchement de la fixation; d’autres essais de déclenchement et
de retenue statiques et dynamiques ne sont pas exclus par le présent essai normalisé.

NORME INTERNATIONALE ISO 9465:2012(F)
Fixations de skis alpins — Déclenchement latéral sous choc —
Méthode d’essai
1 Domaine d’application
La présente Norme internationale définit un essai de choc en vue d’établir le choc latéral maximal sous lequel
un ski d’essai reste solidaire de la semelle d’essai.
L’essai fournit une mesure de la limite entre déclenchement et retenue pour le déclenchement latéral d’une
fixation de ski pour adultes (type A selon l’ISO 9462) pour un réglage donné de cette fixation.
La méthode d’essai est conçue pour simuler les charges de choc latérales survenant en skiant sur la partie
avant du ski. Cet essai permet d’évaluer les propriétés de déclenchement et de retenue d’une fixation de ski
dans des conditions de charges attendues. Cet essai permet également de comparer le déclenchement latéral
causé par un choc latéral sur le ski pour des systèmes de fixation de conception différente.

4 Méthode d’essai
4.1 Principe
La fixation de ski est montée sur le ski d’essai normalisé. La fixation est réglée pour un déclenchement statique
conformément à l’ISO 9462:—, 6.4. Le niveau de déclenchement est noté.
Le ski d’essai est monté sur la semelle normalisée. La semelle est solidement fixée au cours de l’essai.
Le matériau de contact entre le ski d’essai et la pointe de contact est spécifié en 4.2.7.
Le pendule normalisé applique des chocs au ski d’essai au point le plus bas de l’arc du pendule.
Le frottement de l’axe d’articulation du pendule et le matériau de contact sont évalués conformément à 4.2.6.2
et 4.2.7.3 avant et après l’essai de déclenchement des fixations. Ces évaluations sont consignées.
L’angle de lâcher du pendule est progressivement réduit à partir d’une valeur suffisante pour garantir le
déclenchement de la fixation à la suite d’un seul choc sur le ski d’essai jusqu’à l’angle maximal permettant
d’obtenir la rétention de la fixation. L’angle de lâcher provoquant le déclenchement de la fixation de ski à la
limite entre déclenchement et rétention est consigné.
