6.1 The purpose of this specification is to establish minimum impact attenuation requirements for playground surfaces in order to reduce the risk of severe head injury from falls.
6.2 This specification provides a uniform means of quantifying the impact attenuation performance of playground surfaces and is appropriately used to compare the relative performance of different playground surfacing materials.
6.3 This specification is to be used as a reference for specifying the impact attenuation performance of playground surfaces.
6.4 This specification provides a uniform means of comparing the impact attenuation performance of installed playground surfaces with the performance requirements of this specification and with other performance requirements expressed in terms of drop height. Consequently, the specification is appropriately used to determine the actual impact attenuation performance of installed playground surfaces under ambient conditions of use.
6.5 In combination with data relating impact test scores to head injury, the information generated by application of this specification is suitable to estimate the relative risk of a severe head injury due to a fall.
1.1 This specification establishes minimum performance requirements for the impact attenuation of playground surfacing materials installed within the use zone of playground equipment.
1.2 This specification is specific to surfacing used in conjunction with playground equipment, such as that described in Specifications F1148, F1487, F1918, F1951, and F2075.
1.3 This specification establishes an impact attenuation performance criterion for playground surfacing materials; expressed as a critical fall height.
1.4 This specification establishes procedures for determining the critical fall height of playground surfacing materials under laboratory conditions. The laboratory test is mandatory for surfaces to conform to the requirements of this specification.
1.5 The laboratory test required by this specification addresses the performance of dry surfacing materials.
1.6 The critical fall height of a playground surfacing material determined under laboratory conditions does not account for important factors that have the potential to influence the actual performance of installed surfacing materials. Factors that are known to affect surfacing material performance include but are not limited to aging, moisture, maintenance, exposure to temperature extremes (for example, freezing), exposure to ultraviolet light, contamination with other materials, compaction, loss of thickness, shrinkage, submersion in water, and so forth.
1.7 This specification also establishes a procedure for testing installed playground surfaces in order to determine whether an installed playground surface meets the specified performance criterion.
1.8 The results of a field test determine conformance of installed playground surfacing materials with the criterion of this specification and are specific to the ambient conditions under which the test was performed.
1.9 The impact attenuation specification and test methods established in this specification are ......
