significance And Use:

4.1 The dynamic interaction between the athlete and the surface is significant to the performance and comfort of the athlete. Therefore, the ability of the surface to deform under load is... View More

scope:

1.1 This method covers the quantitative measurement and normalization of deflections generated within a sports surface as an indication of the stability and comfort provided by the system.

1.2 Vertical deformation provides a measure for the vertical motion generated within the sports surface system directly below the point of impact which has been normalized to a standard impact force.

1.3 Area deflection provides a measure of the vibrations generated during an impact and their strength at a pre-determined distance from the point of impact.

1.4 This method is not applicable to natural turf, synthetic turf or playground safety surfaces.

1.5 This method is applicable to indoor and outdoor surfaces including but not limited to: wood and synthetic courts, walk/jog/run tracks, tennis courts, dance surfaces, aerobics and general fitness surfaces.

1.6 The methods described are applicable in both laboratory and field settings.

1.7 Area deflection testing is optional, and only applicable to area-elastic, combined elastic and mixed elastic sport surfaces. These include wood surfaces, synthetic surfaces on a sprung wood subfloor, and point elastic surfaces with an internal area elastic component.

1.8 The values stated in SI units are to be regarded as standard. Units provided in parenthesis are informational only.

1.9 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.

1.10 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.
