This specification covers a test method and the corresponding performance requirement for the maximum impact attenuation in all types of turf playing systems installed for North American football fields that is intended to establish a method for identifying and reporting areas within an existing playing system where shock-absorbing properties exceed recommended threshold values. The turf playing system typically includes field areas within and outside the inbound lines extending to the sport specific limit lines as defined by the appropriate regulating body or appropriate standard, or both. All of these areas are regions where an athlete should expect compliant impact attenuation characteristics, but, it does not imply that an injury cannot be incurred if the surface system complies with this specification. The test method, aptly called the free-fall drop test, shall be performed at eight different test point locations for four specific types of surface systems, namely: synthetic turf systems with resilient padding; natural turf systems; combination turf systems; and infill synthetic turf systems.
