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
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9462 was prepared by Technical Committee ISO/TC 83, Sports and recreational equipment,
Subcommittee SC 3, Ski bindings.
This third edition cancels and replaces the second edition (ISO 9462:1993), Clauses 3 and 7/subclauses 5.1,
6.3.3, 6.3.4 and 6.6.2/Tables 1 and 3/Annexes A and B of which have been technically revised/deleted/added.
It also incorporates the Amendment ISO 9462:1993/Amd.1:2002 and the Technical Corrigendum

INTERNATIONAL STANDARD ISO 9462:2006(E)
Alpine ski-bindings — Requirements and test methods
1 Scope
This International Standard specifies the main characteristics of ski-bindings and describes, as an example,
the test methods A and B.
This International Standard applies to ski-bindings for alpine skiing for children, juniors and adults.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 5355:2005, Alpine ski-boots — Requirements and test methods
ISO 8061:2004, Alpine ski-bindings — Selection of release torque values
ISO 9465:1991, Alpine ski-bindings — Lateral release under impact loading — Test method
ISO 9838:1991, Alpine ski-bindings — Test soles for ski-binding tests
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
alpine ski-binding
system to ensure firm connection between boot and ski, fixing the heel low for downhill skiing
NOTE The system releases the boot from the ski when certain loads reach preset values.
3.2
release
detachment of the boot from the ski by release of the mechanism that ensures the connection between boot
and ski
NOTE This release is only considered effective when all the loads due to the boot/ski connection have dropped to
values which present no danger to the skier.
3.3
release values
maximum values of torques M and M caused at the boot/ski connection by the two movements of torsion
z y
and forward bending
See Figure 1.
NOTE 1 These values are generally adjustable on current bindings which have a scale and an indicator displaying the
setting level.
NOTE 2 In the present state of the art, bindings are designed at least to release in torsion (± M ) and in forward
z
bending (± M )
y
3.4
reference value
value, adjusted after a series of tests, used as a basis of comparison to evaluate the behaviour of the binding
during the tests (see 6.3.1)
3.5
combined loading
loading of the sole or ski in several directions at the same time, where one of the loads is the torque M
z
progressively applied to the sole until the binding releases
See Figure 1 and Table 1.

NOTE Each of the load combinations simulates a given situation, chosen within an infinite field of possibilities and
simplified for the purpose of the tests. The main simplification being that the loads applied additionally to the release
torque M are held constant in value and direction during all the release process.

z
3.7
deflection of the ski
deflection of the ski perpendicular to its gliding surface
NOTE In practice, the deflection of the ski depends at the same time on the loading situation and the profile of the
snow-surface (“geometrical” situation); in test simplification, only the “geometrical” situation is simulated.
3.8
type C bindings
bindings suitable for boot soles complying with type C of ISO 5355:2005, which can be adjusted to at least the
following release values:
a) M = 10 N⋅m
z
b) M = 37 N⋅m
y
3.9
type CA bindings
bindings suitable for boot soles complying with types C and A of ISO 5355:2005, which can be adjusted to at
least the following release values:
a) M = 20 N⋅m

The tests shall be performed quasi-statically, ensuring that the following indicative values of the torque
gradient are respected:
a) torsion release:
dM
z
u 50⋅m/s
dt
b) forward bending release:
dM
y
u 220 N⋅m/s
dt
4.2 Accuracy of measurement
The measurement error of the release value in torsion shall be smaller than ± 2 % for values W 50 N⋅m and
± 1 N⋅m for values < 50 N⋅m.
The measurement error of the release value in forward bending shall be smaller than ± 2 % for values
W 200 N⋅m and ± 4 N⋅m for values < 200 N⋅m.
The test equipment shall be designed to allow application of pure moments without any extraneous forces,
during the entire release process.
4.3 Test sole
The test sole shall be in accordance with ISO 9838.
Before testing, the sole shall be degreased, washed and dried.
4.4 Test ski
For the release tests in the laboratory, the bindings shall be mounted either on whole skis or on appropriate
sections of skis. If the binding is pre-mounted (already mounted on the ski by the producer) use the ski with
which the binding is delivered in its medium size. If not, choose a ski which represents the market.
5 Test methods A and B
5.1 Principle
The binding shall be mounted on a ski in accordance with the manufacturer's instructions. A test sole shall
then be inserted in the binding.
In method A, the ski is rigidly connected to the test frame and the torque M or M is progressively applied to
z y
the sole until the binding releases. The peak value of M or M is recorded.
z y
In method B, the sole is rigidly connected to the test frame through a sensor which measures the torques M
z
and M . Forces are progressively applied to the ski until the binding releases. The peak value of M or M is
y z y
recorded.

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.

3 Définitions
Pour les besoins du présent document, les définitions suivantes s'appliquent.
3.1
fixation de ski alpin
dispositif assurant une liaison ferme entre la chaussure et le ski, avec maintien du talon en position basse
pour le ski alpin
NOTE Le dispositif libère la chaussure du ski lorsque certains efforts atteignent des valeurs préétablies.
3.2
déclenchement
libération de la chaussure du ski obtenue par déclenchement du mécanisme assurant la liaison chaussure/ski
NOTE Ce déclenchement n'est considéré comme effectif que lorsque tous les efforts provoqués par l'existence de la
liaison chaussure/ski sont retombés à des valeurs ne présentant plus de danger pour le skieur.
3.3
valeurs de déclenchement
valeurs maximales des couples M et M , occasionnées au niveau de la liaison chaussure/ski par les deux
z y
mouvements de torsion et de chute en avant
Voir Figure 1.
NOTE 1 Ces valeurs sont généralement réglables sur les fixations actuelles qui disposent d'une échelle et d'un
indicateur permettant de visualiser le niveau de réglage.
NOTE 2 Dans l'état actuel de la technique, les fixations sont conçues au moins pour se déclencher en torsion (± M ) et
z
en chute en avant (± M ).
y
3.4
valeur de référence
valeur, ajustée par une série d'essais, servant de base de comparaison pour évaluer le comportement de la
fixation durant les essais (voir 6.3.1)
3.5
charge combinée
application d'efforts sur la semelle ou le ski dans plusieurs directions à la fois, où l'un des efforts correspond
au couple M appliqué progressivement à la semelle jusqu'au déclenchement de la fixation
z
Voir Figure 1 et Tableau 1.

NOTE Chacune des combinaisons d'efforts simule une situation donnée, choisie parmi un nombre illimité de
possibilités et simplifiée pour les besoins des essais. La principale simplification est que les efforts appliqués en plus du
couple de déclenchement M sont maintenus à valeur et direction constantes pendant tout le processus de
z
déclenchement.
3.6
efforts additionnels
efforts appliqués en plus du couple de déclenchement M
z

3.7
déflexion du ski
déflexion du ski perpendiculaire à sa surface de glisse
NOTE En pratique, la déflexion du ski dépend à la fois de la situation de charge et du profil de la surface neigeuse
(situation «géométrique»); à des fins de simplification pour les essais, seule la situation «géométrique» est simulée.
3.8
fixations de type C
fixations adaptées aux semelles conformes au type C de l'ISO 5355:2005 et pouvant être ajustées au moins
aux valeurs de déclenchement suivantes:
a) M = 10 N⋅m
z
b) M = 37 N⋅m
y
3.9
fixations de type CA
fixations adaptées aux semelles conformes aux types C et A de l'ISO 5355:2005 et pouvant être ajustées au
moins aux valeurs de déclenchement suivantes:
a) M = 20 N⋅m
z
b) M = 75 N⋅m

4 Conditions d'essai
4.1 Vitesse d'application des efforts
Les essais doivent être effectués de manière quasi statique, en veillant à ce que les valeurs indicatives
suivantes soient respectées pour le gradient de couple:
a) déclenchement en torsion:
dM
z
u 50 N⋅m/s
dt
b) déclenchement en chute en avant:
dM
y
u 220 N⋅m/s
dt
4.2 Exactitude de mesure
L'erreur de mesure de la valeur de déclenchement en torsion doit être inférieure à ± 2 % pour les valeurs
W 50 N⋅m et à ± 1 N⋅m pour les valeurs < à 50 N⋅m.
L'erreur de mesure de la valeur de déclenchement en chute en avant doit être inférieure à ± 2 % pour les
valeurs W 200 N⋅m et à ± 4 N⋅m pour les valeurs < 200 N⋅m.
Le matériel d'essai doit être conçu de manière à permettre l'application des couples purs exempts de forces
parasites pendant tout le processus de déclenchement.
4.3 Semelle d'essai
La semelle d'essai doit être conforme à l'ISO 9838.
Avant l'essai, la semelle doit être dégraissée, lavée et séchée.
4.4 Ski d'essai
En vue des essais de déclenchement en laboratoire, les fixations doivent être montées soit sur des skis
entiers, soit sur des sections appropriées de skis. Si la fixation est prémontée (c'est-à-dire déjà montée sur le
ski par le fabricant), utiliser le ski livré avec la fixation et choisir la taille moyenne. Dans le cas contraire,
choisir un ski représentatif de l'offre du marché.
5 Méthodes d'essai A et B
5.1 Principe
La fixation doit être montée sur un ski conformément aux instructions du fabricant. Une semelle d'essai doit
ensuite être insérée dans la fixation.
Dans la méthode A, le ski est solidement l
