Standard Test Method for Measuring the Quasi-Static Release Moments of Alpine Ski Bindings

Standard Test Method for Measuring the Quasi-Static Release Moments of Alpine Ski Bindings

SIGNIFICANCE AND USE
This test method involves simulation in the laboratory of potential injury-producing loads that can occur in skiing, without implying the frequency or the magnitude of the danger. This test method does not include the simulation of all or part of a skier, and care must be taken not to confuse the values of moments measured by the test shaft with the loads subjected to the tibia of a skier under the same conditions.
SCOPE
1.1 This test method covers a procedure for the measurement of release moments of ski bindings under conditions where inertia loadings of the ski binding system are not significant.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM F3237-23(Terminology)
Standard Terminology Relating to Snow Sport Freestyle Terrain Park Jumps

SIGNIFICANCE AND USE
2.1 A standard terminology is needed to allow freestyle terrain park designers, builders, ski resorts, accident investigators, and scientists to use a common language in describing freestyle terrain park jumps and related parameters for a jumper using the feature.  
2.2 Angles are taken with respect to horizontal, with positive values indicating an increase in elevation and negative values indicating a decrease in elevation along the path of travel for a terrain park participant using the jump.
SCOPE
1.1 This terminology covers the terms required to describe a cross sectional profile of a snow sport freestyle terrain park jump and related parameters for a jumper using the feature and does not cover any other terrain park feature.  
1.2 The terms are presented in a sequence considered to be the most logical with definitions presented later calling upon those presented earlier. This terminology standard does not require the use of any specific units; Imperial units (feet, seconds, degrees) or metric units (meters, seconds, degrees) can be used.  
1.3 The depictions used in this standard are intended to aid in understanding the definitions and are not intended to depict or describe how any particular terrain park jump or its component features should be designed, built or maintained. Some terrain park jumps may use different configurations or combinations of features, or they may not incorporate all of the features depicted or defined in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with the use of snow sport terrain park features. Snow sports and the use of terrain park features involve inherent risks, and a terrain park feature that complies with all applicable standards or guidelines cannot eliminate all risks associated with terrain park features. Therefore, it is to be clearly understood that compliance with these applicable standards or guidelines in no way guarantees that injury can be prevented.  
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.

ASTM F3557-22(Practice)
Standard Practice for Field Measurements of Snow Sport Freestyle Terrain Jumps

SIGNIFICANCE AND USE
5.1 This practice serves the purpose of measuring snow sports freestyle terrain jump features and may be used as a method for recreating jumps in the field or two-dimensional jump profiles of existing jumps.
SCOPE
1.1 This practice is intended to standardize field measurements of existing snow sport freestyle terrain park jumps. It does not cover other types of terrain park features or asymmetric jumps.  
1.2 This practice is for measuring jumps that are used in public access snow sport freestyle terrain parks discussed in Terminology F3237.  
1.3 For features with multiple takeoffs, each takeoff should be considered as an independent jump and measured according to this practice.  
1.4 The depictions and terrain features used in this standard are intended to aid understanding the definitions and methods and are not intended to depict or describe how any particular terrain park jump or its component features should be designed, built or maintained. Some terrain park features may use components that are not depicted or described in this standard, or they may use different configurations or combinations of components, or they may not incorporate all of the components depicted or defined in this standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with the use of snow sport terrain park features. Snow sports and the use of terrain park features involve inherent risks, and a terrain park feature that complies with all applicable standards or guidelines cannot eliminate all risks associated with terrain park features. Therefore, it is to be clearly understood that compliance with these applicable standards or guidelines in no way guarantees that injury can be prevented.  
1.6 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.8 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.

ASTM F1063-22(Practice)
Standard Practice for Functional Inspections and Adjustments of Alpine Ski/Binding/Boot Systems

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/retention values.  
4.2 The definitions and ranges 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.
SCOPE
1.1 This practice provides procedures for inspection and adjustment of alpine ski/binding/boot systems, including ski binding systems designated as multi-norm bindings and those compatible with “improved walking soles.”  
1.2 This practice should be followed for all ski/binding/boot systems, whether newly mounted or previously mounted, when work is performed on the system that may affect its release function, unless otherwise specified by the binding manufacturer in non-rental applications.  
1.3 This standard is not applicable to ski/binding/boot rental systems, including incomplete systems, except when a customer intends to use his or her own skis/bindings with the shop’s boots (as provided in Subsection 7.3 of Practice F1064). For more information on ski/binding/boot rental shop practices, for both complete and incomplete systems, consult Practice F1064.  
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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.

ASTM F1064-21(Practice)
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.
