ASTM F2333-04(2017)

5.1 This test method will be used by athletic footwear manufacturers to characterize the traction of the athletic shoe-sports surface interface, and as a tool for development of athletic shoe outsoles.

5.2 This test method will be used by researchers to determine the effect of sport surface conditions (for example, moisture, grass species, turf density, soil texture, soil composition, and so forth) on traction characteristics of the athletic shoe-sports surface interface.

5.3 This test method will be used by sports surface manufacturers to characterize the traction of the athletic shoe-sports surface interface, and as a tool for development of sports surfaces.

5.4 Careful adherence to the requirements and recommendations of this test method will provide results that compare with results from different laboratory sources.

5.5 The method will be used to research relationships between traction at athletic shoe-sports surface interfaces and athletic performance or injury. This research may lead to recommendations for appropriate levels of traction.

1.1 This test method covers specifications for the performance of sports shoe-surface traction measuring devices, but does not require a specific device or mechanism to be used. Figs. 1 and 2 show schematic diagrams of generic apparatus.

1.2 This test method is appropriate for measuring the effects of athletic shoe outsole design and materials on traction at the shoe-surface interface.

1.3 This test method is appropriate for measuring the effects of sport surface design and materials on traction at the shoe-surface interface.

1.4 This test method specifies test procedures that are appropriate for both field and laboratory testing.

1.5 Traction characteristics measured by this test method encompass friction forces developed between shoe outsoles and playing surfaces.

1.6 Traction characteristics measured by this test method encompass traction achieved by penetration of cleats or studs into playing surfaces.

1.7 This test method specifies test procedures for the measurement of traction during linear translational motion and rotational motion, but not simultaneous combinations of linear and translational motion.

1.8 The loads and load rates specified in this test method are specific to sports activities. The test method is not intended for measurement of slip resistance or traction of pedestrian footwear.

1.9 Test results obtained by this method shall be qualified by the characteristics of the specimen.

1.10 This test method does not establish performance or safety criteria. The level of traction required between a sport shoe and surface varies with the level of performance and from individual to individual. The extent to which particular levels of traction contribute to individual athletic performance and risk of injury is not known.

1.11 The values stated in SI units are to be regarded as the standard.

1.12 This standard may involve hazardous materials, operations and equipment. 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.

1.13 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.
