ASTM F1064-21

Standard Practice for Sampling and Inspection of Complete and Incomplete Alpine Ski/Binding/Boot Systems in Rental Applications

SIGNIFICANCE AND USE
5.1 The purpose of this practice is to aid in providing the end user with an appropriate functioning ski/binding/boot system and associated release/retention characteristics by providing the rental facility with an ongoing program for monitoring the appropriateness of functional characteristics of the system. It is assumed that these procedures are integrated into the maintenance and operating procedures specified by the equipment manufacturers (for example, in manufacturer-provided technical manuals). This practice is not intended to create additional or redundant requirements for the rental facility. However, this practice should be the basis for the development of rental procedures if the equipment manufacturer’s maintenance and operating procedures do not specifically state that they are in compliance with this practice. This practice will aid the rental facility in providing the end user with a system that provides appropriate release/retention characteristics.  
5.2 This practice is applicable to rental facilities that use releasable alpine ski bindings. It is not intended as a method for evaluating equipment designs or types, such as alpine touring equipment. Mixing components of different system types (for example, using an alpine touring boot in an alpine binding) is discouraged.
SCOPE
1.1 This practice establishes a uniform method for the sampling and inspection of complete and incomplete Alpine ski/binding/boot systems used in rental operations. This practice is appropriate for use in rental applications in which all or part of the functional components of the system are supplied by the rental facility.  
1.2 This practice should be followed by any facility that rents complete or incomplete Alpine ski/binding/boot systems to an end user.  
1.3 This practice is not intended for use with other ski boot or bindings systems, such as alpine touring or pin/tech systems. Use of ski boots or ski bindings that do not meet the requirements for alpine ski equipment can cause unexpected release and retention characteristics.  
1.4 This standard does not apply to a ski/binding/boot system that is rented to one individual for the majority of a season and not returned to the rental inventory until the end of the season (often referred to as a seasonal rental); such systems will follow the practice provided in Practice F1063.
Note 1: Refer to Practice F1063 for equivalent procedures and tolerances for retail systems.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM F1064-21, titled Standard Practice for Sampling and Inspection of Complete and Incomplete Alpine Ski/Binding/Boot Systems in Rental Applications, provides a uniform approach for monitoring and inspecting ski equipment in rental settings. Developed by ASTM International, this standard is designed to help rental facilities ensure that each rented alpine ski/binding/boot system is functioning properly and offers appropriate release and retention characteristics to the end user.

By incorporating ongoing inspection and testing procedures, ASTM F1064-21 enhances the operational quality of rental fleets and helps maintain equipment safety in accordance with manufacturer specifications and international standardization principles.

Key Topics

• Scope and Applicability:

  • Applicable to all rental facilities offering complete or incomplete alpine ski/binding/boot systems with releasable bindings.
  • Excludes alpine touring, pin/tech systems, and seasonal (full-season) rentals, which are covered by ASTM F1063.
  • Discourages mixing components from incompatible system types.

• Inspection and Sampling Procedures:

  • Preseason inspections of boots and bindings for compatibility, interchangeability, and functionality.
  • In-season random sampling (usually 5% of inventory; min. 16, max. 80 units) and functional testing at defined intervals.
  • Additional sampling or corrective action is required if deviations are detected.

• Deviation and Tolerance Criteria:

  • Establishes classes of deviation (Class I to III) to determine when maintenance, corrective action, or risk review is required.
  • Specifies visual indicator settings, reference values, and torque tolerances as outlined by the binding manufacturer.
  • Includes random sampling methodology to ensure representative inventory testing.

• Inspection of Incomplete Systems:

  • Provides requirements for assembling and inspecting systems when customers provide part of the equipment, ensuring compatibility and safety.

• Integration with Equipment Manufacturer Procedures:

  • Supplements, but does not replace, manufacturer-recommended maintenance and operating procedures.
  • Serves as a default framework when manufacturer procedures are not explicit.

Applications

ASTM F1064-21 is valuable for ski rental shops, equipment maintenance providers, and quality control personnel responsible for the safety and performance of ski equipment in a rental environment. Key practical applications include:

• Rental Shop Operations: Implementing rigorous, standardized inspection protocols to minimize equipment-related failures, reduce injury risk, and maintain compliance with industry best practices.
• Inventory Management: Structuring maintenance schedules, inspection intervals, and record-keeping based on inventory size and usage.
• Customer Equipment Validation: Evaluating customer-supplied boots or bindings for compatibility with rental fleets, ensuring safe equipment assembly, and providing alternatives when requirements are not met.
• Training and Quality Assurance: Assisting in staff training by defining clear procedures for identifying equipment deviations and applying corrective actions promptly.

Related Standards

ASTM F1064-21 aligns with other leading ski equipment standards and international guidelines, including:

• ASTM F939: Practice for Selection of Release Torque Values for Alpine Ski Bindings
• ASTM F1063: Practice for Functional Inspections and Adjustments of Alpine Ski/Binding/Boot Systems (retail and seasonal rental systems)
• International Standardization Principles: Developed in accordance with WTO Technical Barriers to Trade guidelines

For comprehensive quality management and equipment safety, ski rental facilities should use ASTM F1064-21 alongside these related ASTM practices and manufacturers’ technical recommendations.

INTRODUCTION
Adhering to these guidelines may help to reduce the risk of injuries resulting from improper
mechanical functioning of releasable binding systems. However, skiing involves inherent and other
risks. Injury can result from simply falling down, impact with an object, or from many other actions.
Many injuries are unrelated to system function. Furthermore, even a properly functioning system
cannot protect the skier in all situations. Therefore, it is to be clearly understood that compliance with
these guidelines in no way guarantees that injury can be prevented.

a ski or any individual system components (for example, a single boot or a single ski-binding).
3.1.4 visual indicator setting—the setting displayed on the binding’s release/retention adjustment scale.
3.1.5 measured release value—release torque value determined by the use of a testing device of the type defined in Annex A1.
3.1.6 test result—the middle quantitative value of three repetitions of the same test.
3.1.7 inspection range—the 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.
3.1.7.1 Discussion—
Any of the three methods described above for determining the range may be used as differences will be insignificant.
3.1.8 Class I deviation—in-use range (also called “re-adjustment range”)—a minor deviation the maximum difference between
the reference torque value and the test result that does not require corrective action, defined as 616 to 30 %, or action. Defined
630 % of the reference torque value, or 66 Nm for twist and 620 Nm for forward lean, whichever is greater, or two horizontal
rows up or down from the selected reference torque value as determined on the binding manufacturer’s adjustment chart. Class
I deviations Results in this range are used to determine the frequency of sampling. Results that are beyond the inspection range
but still in this range do not require corrective action.
3.1.8.1 Discussion—
Any of the three methods described above for determining the range may be used as differences will be insignificant.
3.1.2 Class II deviation—a minor deviation that prompts inspection of the entire inventory and corrective action, defined as 631
to 45 %, or three horizontal rows up or down from the selected reference torque value as determined on the binding manufacturer’s
adjustment chart.
3.1.3 Class III deviation—a major deviation that prompts corrective action and a review of all procedures, defined as more than
645 %, or more than three horizontal rows up or down from the selected reference torque value as determined on the binding
manufacturer’s adjustment chart. The in-season sampling and inspection program is designed to render the occurrence of a Class
III deviation unlikely.
3.1.9 clean versus lubricated tolerance—the accepted difference between clean and lubricated test result(s), defined as not more
than 20 % of the clean test, used whenever a functional test for binding-boot compatibility is required.
3.1.5 correction factor—the value that must be added or subtracted from the initial visual indicator setting to bring the test result
within the inspection tolerance (see 3.1.9).

4. Summary of Practice
4.1 Prior to the beginning of each season, boots and bindings components of boot/binding systems are inspected and tested
individually for compatibility and interchangeability using a testing proper function. Testing must be conducted with a device as
defined in Annex A1 of Practice F1063.
4.2 At specified intervals throughout the operating season, samples are taken from rental inventory and inspected. Test results are
used to determine sampling frequency and prompt corrective action when specified tolerances are exceeded.
5. Significance and Use
5.1 The purpose of this practice is to aid in providing the end user with an appropriate functioning ski/binding/boot system and
associated release/retention valuecharacteristics by providing the rental facility with an ongoing program for monitoring the
appropriateness of functional characteristics of the system. It is assumed that these procedures are integrated into the maintenance
and operating procedures specified by the equipment manufacturers. manufacturers (for example, in manufacturer-provided
technical manuals). This practice is not intended to create additional or redundant requirements for the rental facility. However,
this practice should be the basis for the development of rental procedures if the equipment manufacturer’smanufacturer’s
maintenance and operating procedures do not specifically state that they are in compliance with this practice. This practice will
aid the rental facility in providing the end user with an a system that provides appropriate release/retention value.characteristics.
5.2 This practice is applicable to rental facilities that use releasable Alpinealpine ski bindings. It is not intended as a method for
evaluating equipment design.designs or types, such as alpine touring equipment. Mixing components of different system types (for
example, using an alpine touring boot in an alpine binding) is discouraged.
6. Test Device
6.1 All tests specified in this practice are made with a device that indicates torque. Such a device should be inspected annually
by the rental facility and calibrated biannually by a qualified technician in accordance with Annex A2.
7. Equipment Inspection Requirements
7.1 Preseason Inspection—Prior to the beginning of each season and whenever new inventory is added, an inspection should be
made of the components of the release/retentionski/binding/boot system. Units that do not meet the specified tolerances are
repaired, modified, or replaced.
7.1.1 A visual inspection for compatibility and interchangeability is performed on all boots in accordance with the procedures
recommended by the binding manufacturer.
7.1.2 As a check on boots that are new to inventory, a single unit sample, by make, model, and shell size, is taken and tested in
accordance with the procedures in Section9.1.1 and 99.1.2. If a boot fails, all boots in the category for any shell size and type, a
boot does not produce acceptable results, all new boots are visually inspected for the defect and as a check, a 16-unit (or less if
16 are not available) random sample is taken and tested in accordance with the procedures in Section9.1.1 and 99.1.2. If any boots
in this sample fail, do not produce acceptable results, all remaining boots in the category new boots of that make, model, and shell
size are tested.
F1064 − 21
7.1.3 As a check on boots that have been accepted into inventory in a prior season, a 5 % (not less than 16 nor more than 80-unit)
sample random sample of each make, model, and shell size is taken and tested in accordance with the procedures in Section9.1.1
and 99.1.2. If a boot fails, does not provide acceptable results, all boots in that make, model, or age category are visually inspected
for the defect. If the defect is found in another boot category, all boots in that category also make and model are visually inspected.
If another boot of the same make, model, and shell size does not pass visual inspection, then all boots of that make, model, and
shell size are tested in accordance with the procedures in Section 9. Any boot in this series of testing that does not produce
acceptable results needs to be repaired, replaced, or removed from the rental fleet.
7.1.4 Boots that meet the criteria for compatibility but do not meet the criteria for interchangeability are used in non-
interchangeable rental programs only.
7.1.5 Preseason tests for compatibility or interchangeability, or both, of the boot need not be made if the binding manufacturer’s
current operating procedures specifically state that the boot is not a functional component of the release system and that such tests
are unnecessary.
7.1.4 Bindings used in an interchangeable rental program are inspected for appropriate function and valid visual indicator setting
in accordance with the procedures in Section 99.1.3.
7.1.7 Bindings used in a non-interchangeable system are tested for appropriate function and valid visual indicators whenever a
new system is created, whenever called for as a result of the sampling procedure, or when recommended by the binding
manufacturer.
7.1.5 Bindings that incorporate a single means of adjustment for all release directions are tested in either twist or forward lean but
need not be tested for both during the preseason inspection. However, Each binding in the rental fleet is tested in the preseason
except for new manufacturer pre-mounted ski-binding systems that include systems in which the toe and heel components are slid
onto pre-mounted or integrated tracks. For these new manufacturer pre-mounted ski-binding systems, a 5 % (but not less than 16
nor more than 80-unit) random sample of bindings is tested in both directions twist and forward lean by the procedure in Section
99.1.3. If a binding fails, a visual inspection for the defect is conducted on all bindings. All bindings, in any binding category in
which a defective unit is found, are tested in accordance with the procedures in Section 9.
7.1.6 If a binding does not produce results in the inspection range when using a test reference boot, the binding manufacturer’s
troubleshooting procedures are initiated and all bindings in the category are tested in accordance with the procedures in 9.1.3. The
bindings may be retested once after the troubleshooting procedures. If the bindings continue to produce results outside the
inspection range, they must be removed from the rental fleet.
7.2 In-Season Inspection—At regular intervals, as specified in Section 8, samples are taken from the rental inventory and evaluated
in accordance with the procedures in Section 99.2.
7.2.1 The inventory fails the sample if a Class I deviation is detected in If more than 20 % of the units in the sample, sample
produce results outside the inspection range but within the in-use range, or if a single Class II deviation is detected.system produces
results outside the in-use range, follow the manufacturers troubleshooting procedures and initiate daily testing as required by
Section 8.
7.2.2 If a Class II deviation is detected in the sample, system produces results outside the in-use range, the cause must be
identified and the entire rental inventory inspected for the defect and appropriate corrections made. All pertinent procedures as
defined by the binding manufacturer are reviewed and corrective action taken with the entire rental inventory.
7.2.2.1 Class I deviations, when detected, Systems that produce results outside the inspection range but within the in-use range,
need not be corrected.
7.2.3 If a Class III deviation is detected in the sample, all pertinent procedures as defined by the binding manufacturer are reviewed
and corrective action taken to the entire rental inventory.
7.3 Incomplete Inspection—An inspection of the type described in 7.3.1, 7.3.2, or 7.3.3 is conducted each time an incomplete
rental system is assembled during the rental transaction.
7.3.1 The equipment is assembled, adjusted, and inspected according to normal rental procedures as defined in this practice,
