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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 83, Sports and other recreational facilities and
equipment, Subcommittee SC 4, Snowsports equipment.
This fifth edition cancels and replaces the fourth edition (ISO 11088:2006), which has been technically
revised where Annex F (informative) has been removed.

Introduction
International Standards exist for the components of the alpine ski/binding/boot (S-B-B) system, mainly
intended for the component manufacturers. An International Standard (ISO 8061) also exists for the
selection of release moments. The present International Standard is intended primarily for retailers.
However, its aim is to include in one text the different phases of the choice of components, their
assembly, adjustment and inspection in the form of practical procedures, and to provide tolerances for
inspection and adjustment.
The inspection procedures and tolerances described in this International Standard apply to the
condition of the S-B-B system before it leaves the ski shop and are not intended to be used to judge the
condition of the equipment once it is put into use.

INTERNATIONAL STANDARD ISO 11088:2015(E)
Assembly, adjustment and inspection of an alpine ski/
binding/boot (S-B-B) system
1 Scope
This International Standard specifies assembly, adjustment and inspection procedures for the binding
mechanisms of skis, integrating in a practical way, the requirements of those International Standards
which are related to skis, bindings and boots.
It is intended for all individuals and institutions concerned with those procedures, and especially for
sports retailers.
It is applicable to a ski/binding/boot system (S-B-B) for alpine skiing, of which at least one component
is owned by the user.
NOTE In the case where the two components (SB and B) are rented, ISO 13993 gives a method of
measurement by sampling as an alternative to systematic measurement, before delivery to the end-user.

The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
fitting adjustment
procedure required to obtain geometric compatibility and correct functioning of different components
3.2
indicator value
Z-mark
release indicator value marked on the binding in accordance with ISO 9462

3.3
skier type
release adjustment criteria pertaining to the type of skiing to be undertaken, as assessed by the skier in
accordance with Table A.1
Note 1 to entry: The designations L, A, S, which were used in ISO 8061:1984, have been replaced by types 1, 2 and
3, respectively, in ISO 8061:1991 and in ISO 8061:2004.
Note 2 to entry: If the skier desires a setting outside the tolerances of this International Standard, he or she can
select such a setting at his or her own discretion. Ski-binding manufacturers should provide guidelines to shops
and skiers regarding the recommended magnitude of such changes. Skiers should be clearly informed when these
changes result in release values above the upper limit or below the lower limit defined in ISO 8061.
3.4
initial indicator position
release indicator position of the binding corresponding with the instructions given in Table B.1
3.5 Release moment (values) M and M
Z Y
3.5.1
selected individual release moment
reference moment
〈for a given skier〉 release moment determined in accordance with ISO 8061
3.5.2
measured release moment
〈for a given S-B-B system〉 average or middle quantitative value of three consecutive release
measurements in the same direction on the same unit
Note 1 to entry: It is expressed in newton metres.
3.6
deviation accepted for the setting
inspection tolerance
maximum difference between the measured release moment (3.5.2) and the selected individual release
moment (3.5.1)
Note 1 to entry: This difference, which may be reduced by the setting, is limited for M to ±15 % or 3 N⋅m
Z
(whichever is greater), and for M to ±15 % or 10 N⋅m (whichever is greater).
Y
3.7
release adjustment
procedure for making the measured M and M values coincide with the selected individual M and M
Z Y Z Y
values within the limits stated in Table B.1
3.8
trouble-shooting procedures
additional procedures recommended by the equipment manufacturer
3.9
deviation accepted for the re-adjustment
re-adjustment tolerance
maximum difference between the measured release moment (3.5.2) at the initial indicator position (3.4)
and the selected individual release moment (3.5.1)
Note 1 to entry: This difference, which may be reduced by re-adjustment, is limited for M to ±30 % or 6 N⋅m
Z
(whichever is greater), and for M to ±30 % or 10 N⋅m (whichever is greater).

4 Skier’s parameters
4.1 General
The individual release moment values are given in ISO 8061. The following procedure using discrete
values may be considered as an acceptable approximation of the basic functions of ISO 8061.
4.2 Weight method
4.2.1 Determine the skier’s parameters with the following:
— mass (weight);
— height;
— type (according to Annex A);
— age;
— sole length if necessary.
