ASTM WK15822

    Work Item: ASTM WK15822 - New Guide for Measuring Force Reduction and Vertical Deformation on Synthetic Turf Systems

    (What is a Work Item?)

    Developed by Subcommittee: F08.65 | Committee F08 | Contact Staff Manager



    1. Scope

    1. Scope 1.1 Force Reduction (FR) and Vertical Deformation (VD) are two properties used to characterize the interaction between an athlete and an athletic playing surface. For turf surfaces, groups have measured the FR and VD of natural grass fields that have been classified as high performing by athletes using the fields. The FR and VD measured on these fields have been used by sports governing bodies, such as FIFA and IRB, to establish minimum and maximum values for high performing synthetic turf systems that correspond to the range of values measured on the high performing natural grass fields. 1.2 This guide establishes a minimum FR and minimum and maximum VD for general purpose athletic fields. It provides a minimum performance standard. 1.3 This guide applies to complete turf systems and not to the components of the synthetic turf systems. 1.4 These tests, as a group, can be used to specify the performance properties of a synthetic turf system. 1.5 These tests are not biomechanical tests. 1.6 These tests can be performed in a laboratory environment or on installed fields. 1.7 This guide 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.

    The only ASTM synthetic turf standard that measures performance for the athlete using the synthetic turf is F-1936 for measuring g-max in the field. F-1551 recommends test procedures that measure properties of the turf and turf components, but not sport performance properties. The guide being balloted is an attempt to recommend performance criteria for Force Reduction and Vertical Deformation that can be used by specifiers or sport governing bodies as performance criteria for synthetic turf systems. Recommended minimum values for Force Reduction and Vertical Deformation are made for general purpose fields.
