Specifications include, but are not limited to: 1.1 This specification establishes anin situtest method andmaximum impact attenuation value for all types of turf playingsystems and for a number of sport-specific field layouts. It alsoincludes a protocol for determining test point locations onfields that are lined for multiple sports.1.1.1 Turf playing systems may be located outdoors orindoors, and typically include field areas within the in-boundslines and areas outside the in-bounds lines extending tosport-specific limit lines; areas where an athlete should expectto encounter impact attenuation performance that complieswith this specification.1.1.2 Site-specific conditions may exist wherein non-turfsurface materials, such as track surfacing and/or covers oversubsurface structures, are found within the boundaries of thelimit lines. These alternate surface materials are not included inthe scope of this specification.1.2 This specification establishes a method for reporting testresults and identifying areas within an existing turf playingsystem where impact attenuation measurements exceed re-quired threshold values.1.3 Nothing in this specification is intended to imposelimitations on what fields can be tested, or how a particularfield can be used. Test providers can adapt the procedures andguidelines contained herein to tests performed on any turfplaying system.
