Overview

ASTM F1063-22 sets forth a standardized practice for the functional inspection and adjustment of alpine ski/binding/boot systems, including multi-norm bindings and those designed for use with improved walking soles. Published by ASTM International, this standard is vital for improving user safety by ensuring that ski equipment is set up with appropriate release and retention values. While not intended for evaluating equipment design or rental shop practices, ASTM F1063 addresses best practices for both newly mounted and previously serviced ski/binding/boot systems in retail settings.

Key Topics

• Scope and Applicability:

  • Applies to functional inspections and adjustments of complete alpine ski/binding/boot systems.
  • Excludes rental systems, except when customer equipment is combined with shop boots (per F1064).
  • All values and procedures are referenced in SI units.

• Inspection Procedures:

  • Functional Inspections: Includes assessment of boot-to-binding adjustments and clearances, symmetry of torsional release, boot-binding compatibility, and elastic travel.
  • Release Torque Value Inspections: Requires measuring the torque needed for binding release (twist and forward lean) using calibrated devices in line with ASTM F1061.
  • Reference Value Selection: Draws on manufacturer’s charts aligned with ASTM F939 guidelines to ensure proper release/retention force.

• Tolerance and Adjustment:

  • Defines acceptable inspection and in-use tolerances for release torque values.
  • Emphasizes corrective actions or adjustments only within specified ranges; otherwise, manufacturer consultation is required.

• Reporting:

  • Shop-generated inspection reports must include skier parameters, visual indicator settings, inspection pass/fail status, and relevant manufacturer recommendations.

Applications

ASTM F1063-22 delivers significant practical value across ski shops, equipment manufacturers, and technicians by:

• Providing a unified approach to safety checks and tuning of ski/binding/boot systems.
• Reducing risk of injury due to improper mechanical function or settings.
• Guiding service personnel through structured procedures to inspect, test, and adjust components, promoting consistency and reliability.
• Helping identify boot-binding compatibility issues, especially with boots featuring improved walking soles or non-standard interfaces.
• Supporting customer confidence with detailed documentation on equipment readiness for use.
• Complementing training and reproducibility methods for multiple operators, enhancing quality control.
• Aiding in evaluating and servicing both new and used equipment with defined inspection and diagnostic steps.

Related Standards

Adoption of ASTM F1063-22 is reinforced by a suite of related ASTM and ISO standards:

• ASTM F504 - Test Method for Measuring the Quasi-Static Release Moments of Alpine Ski Bindings
• ASTM F939 - Practice for Selection of Release Torque Values for Alpine Ski Bindings
• ASTM F1061 - Specification for Ski Binding Test Devices
• ASTM F1064 - Practice for Sampling and Inspection of Alpine Ski/Binding/Boot Rental Systems

Relevant ISO Standards:

• ISO 5355 - Ski Boots for Downhill Skiing - Interface requirements
• ISO 8061 - Selection of Release Torque Values
• ISO 9462 - Alpine Ski Binding Safety Requirements and Test Methods
• ISO 11088 - Assembly, Adjustment, and Inspection of Alpine Ski-Binding-Boot Systems

INTRODUCTION
Adhering to these guidelines may help reduce the risk of injuries resulting from improper
mechanical functioning of releasable alpine binding systems. Skiing involves inherent risks and injury
can result from simply falling down, impact with an object, or from many other actions. Many injuries
are unrelated to ski/binding/boot system function and a properly functioning system cannot protect the
skier in all situations. Compliance with these guidelines in no way guarantees that injury will be
prevented.

3.1 Definitions:
3.1.1 clean versus lubricated tolerance—system—accepted difference between clean and lubricated test results, defined as not
more than 20 % of the clean test, used whenever a functional test for binding-boot compatibility is required (seea group of
interacting components, usually comprised of a 6.3). ski, binding, and boot.
3.1.2 clockwise versus counterclockwise tolerance—accepted difference between test results about an axis perpendicular to the
plane of the ski, usually from the toe piece component, and defined as within the inspection tolerance.
3.1.3 corrective action—procedures other than readjustment of the visual indicator setting (see 3.1.18) to include repair or
replacement of system components.
3.1.4 deviation—difference between the test result (see 3.1.16) and the selected reference torque value (see 3.1.12), usually
expressed as a percentage of the selected reference torque value.
3.1.5 in use tolerance—accepted difference between the reference torque value and the test result(s), defined as 630 % of the
reference torque value, or 65 Nm for twist and 20 Nm for forward lean, whichever is greater, or two horizontal rows up or down
from the selected reference torque value determined on the binding manufacturer’s adjustment chart. In the absence of an
applicable manufacturer’s chart, use Annex A2. For non-rental applications, this tolerance is used as the upper and lower limit for
determining if system release values are acceptable for in-use or in-service purposes, after said system has been released to the
customer. This limit is derived from Practice F1064, 3.1.1 Class 1 deviation. This deviation (616 to 30 %, or two horizontal rows
up or down from the selected reference torque value) is defined as a minor deviation that does not require corrective action for
equipment that is in-service, in rental applications. It is used as the upper and lower limit for readjustment of the binding.
3.1.6 initial visual indicator setting—visual indicator setting derived from the binding manufacturer’s adjustment chart.
3.1.2 inspection tolerance—incomplete system—accepted difference between the reference torque value and the test result.
Defined as 615 % of the reference torque value, or 63 Nm for twist and 610 Nm for forward lean, whichever is greater, or one
horizontal row up or down from the selected reference torque value determined on the binding manufacturer’s adjustment chart,

3.1.5 release preference—(previously skier type) classification of I, II, or III that is selected by the skier and corresponds to the
balance between release and retention of the ski/binding/boot system.
3.1.5.1 Type I—designation that provides lower release/retention values; corresponds to an increased risk of inadvertent binding
release in order to gain releasability in a fall; also applies to entry level skiers uncertain of their release preference.
3.1.5.2 Type II—designation that provides release/retention values appropriate for most recreational skiing; applies to skiers not
classified as in I or III.
3.1.5.3 Type III—designation that provides higher release/retention values; corresponds to decreased releasability in a fall in
order to gain a decreased risk of inadvertent binding release.
3.1.5.4 (/)—a symbol that separates release preference designations, used when, as a result of troubleshooting, different release
preferences have been selected for determining twist (M ), and forward lean (M ) release/retention values; shown in the order

higher or lower than the normal setting range:
(1) (–)—a symbol, that when placed to the left of release preference I (see 3.1.5.1), provides release/retention values lower than
release preference I, corresponds to a further increase in the risk of inadvertent binding release in order to gain increased
releasability in a fall.
(2) (+)—a symbol, that when placed to the right of release preference III (see 3.1.5.3), provides release/retention values higher
than release preference III, corresponds to a further decrease in releasability in a fall in order to gain a decreased risk of inadvertent
binding release.
3.1.11.1 discretionary settings—visual indicator settings higher or lower than the normal setting range:
(1) (–)—a symbol, that when placed to the left of Type 1 (see 3.1.14.1), provides release/retention values lower than Type I,
corresponds to a further increase in the risk of inadvertent binding release in order to gain increased releasability in a fall.

3.1.10 inspection range—accepted difference between the reference torque value(s) and the test result(s), defined as 615 % of the
reference torque value, or 63 Nm for twist and 610 Nm for forward lean, whichever is greater, or one horizontal row up or down
F1063 − 22
from the reference torque value determined on the binding manufacturer’s adjustment chart (see Annex A2). It is used as the
criteria for prompting consultation of the binding manufacturer’s troubleshooting procedures or readjustment of the binding, or a
combination of both.
3.1.10.1 Discussion—
When an algorithm or table is used to provide a value, either may be used (differences may be insignificant).
3.1.11 skier type—in-use range—classification, selected by the skier, for the type of skiing to be undertaken.accepted difference
between the reference torque value(s) and the test result(s), defined as 630 % of the reference torque value, or 65 Nm for twist
and 20 Nm for forward lean, whichever is greater, or two horizontal rows up or down from the selected reference torque value
determined on the binding manufacturer’s adjustment chart.
3.1.11.1 Discussion—
In the absence of an applicable manufacturer’s chart, use Annex A2. This range is used as the upper and lower limit for determining
if system release/retention values are acceptable for in-use or in-service purposes, after the ski/binding/boot system has been
released to the customer; values in this range are considered acceptable. This limit is derived from the in-use range found in
Practice F1064, 3.1.8 that is (616 to 30 %, or two horizontal rows up or down from the selected reference torque value). It is used
as the upper and lower limit for readjustment of the binding.
3.1.11.2 Discussion—
When an algorithm or table is used to provide a value, either may be used (differences may be insignificant).
3.1.14.1 Type I—designation that provides lower than average release/retention values; corresponds to an increased risk of
inadvertent binding release in order to gain releasability in a fall; also applies to entry level skiers uncertain of their classification.
3.1.14.2 Type II—designation that provides average release/retention values appropriate for most recreational skiing; applies to
skiers not classified as in Type I or Type III.
3.1.14.3 Type III—designation that provides higher than average release/retention values; corresponds to decreased releasability
in a fall in order to gain a decreased risk of inadvertent binding release.
3.1.14.4 (/)—a symbol that separates skier type designations, used when, as a result of troubleshooting, different skier types have
been selected for determining twist (M ), and forward lean (M ) release/retention values; shown in the order (twist/forward lean)
x z
or (T/H) to denote toe piece (T) and heel piece (H) of this ski binding. Other conventions may be used to record different skier
types for twist and forward lean when required by the documentation

plane of the ski, usually from the toe piece component, and defined as within the inspection tolerance.
3.1.14 corrective action—procedures other than readjustment of the visual indicator setting (see 3.1.4) to include repair or
replacement of system components.
3.1.15 limit for readjustment—accepted difference between the reference torque value (see 3.1.8) and test result(s) (see 3.1.3.2),
defined as 630 % of the reference torque value, or 65 Nm for twist and 20 Nm for forward lean, whichever is greater, or two
horizontal rows up or down from the selected reference torque value determined on the binding manufacturer’s adjustment chart
(see Annex A2).
3.1.15.1 Discussion—
For a reference torque value of 8 Nm in twist and 29 Nm in forward lean (Skier Code A in Annex A2), the limit for readjustment
is one row up or two rows down on the adjustment chart. The limit for readjustment is used as the upper and lower limit for
troubleshooting (see 3.1.17) – bindings beyond this cannot be adjusted for use by the customer.

4. Significance and Use
4.1 The purpose of this practice is to aid in providing the end user with an appropriately functioning ski/binding/boot system with
appropriate release torque setting(s). release/retention values.
4.2 The definitions and tolerancesranges defined in this practice do not necessarily apply to procedures incorporating an inspection
interval or schedule, in which such procedures are specified by the binding manufacturer. This practice is not intended to be a
method for evaluating equipment design.
NOTE 2—Refer to Practice F1064 for definitions and tolerances pertaining to the evaluation of equipment once in use.
5. Procedure
5.1 Inspections—Two types of inspection procedures are described in this practice: (1) procedures to check the system for
appropriate function, and (2) procedures to check the system for appropriate release torque calibration release/retention values (see
Appendix X4). In all procedures requiring a measured release value, the system testing device should meet Specification F1061
and be checked by the method described in Annex A1.
5.1.1 Functional Inspections—These inspections shall include inspection of all boot-to-binding adjustments and clearances,
appropriate elastic travel (see 6.1), symmetry of torsional release, boot-binding compatibility (see 6.3), and other inspections
recommended by the equipment manufacturers (see Appendix X4).
5.1.2 Release Torque Value Inspections—The release torque value of the system, as assembled for use, shall be inspected with the
use of a system testing device (see Annex A1). A description of release torque value inspections and tolerances is included in this
practice (see Section 7 and Appendix X4).
5.2 Reference Torque Value Selection—Reference torque values for release torque may be selected using Annex A2 or tables
supplied by the binding manufacturer or system testing device manufacturer, which are in accordance with Practice F939.
Reference torque values above the upper limit specified by Practice F939 or above the binding manufacturer’s recommendations
should not be used. Values below the lower limit or below the binding manufacturer’s recommendations may
