Playground Equipment Safety Standards

Several Playground Equipment Safety Standards have been developed by ASTM International (ASTM), defining safety specifications for playground equipment in an effort to make playgrounds safer for children. These standards address safety specifications for home and public playground equipment, trampolines, soccer goals, and inflatable play devices.

According to the Center for Disease Control (CDC) more than 200,000 children 14 years of age and younger are treated for playground related injuries in hospital emergency rooms across the United States each year. These injuries ranged from bruises, lacerations, fractures, and sprains. These safety issues have proven to be costly in the dearest manner possible. Furthermore, in 1995, playground-related injuries among children ages 14 and younger cost over $1.2 billion.

The National Program for Playground Safety (NPPS) is a leader in advocating for the creation of safe public play environments for children and providing resources and information for safe outdoor play in the United States. They serve as advocates for children on issues that relate to playground safety before government and regulatory agencies. The Consumer Product Safety Commission (CPSC) is also committed to protecting children from sustaining injuries on the playground. The CPSC has written a handbook (PDF link) that contains important safety information for those who purchase, install, and maintain public playground equipment.

ASTM F1292-18e1

Standard Specification for Impact Attenuation of Surfacing Materials Within the Use Zone of Playground Equipment

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 , CSAZ614 (Canada), and SS457 (Singapore). 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 This specification also provides optional procedures to determine the critical fall height under wet or frozen test conditions, or both. 1.7 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. 1.8 The impact attenuation specification and test methods established in this specification are specific to the risk of head injury. There is only limited evidence that conformance with the requirements of this specification reduces the risk of other kinds of serious injury (for example, long bone fractures). Note 1: The relative risk of fatality and of different degrees of head injury may be estimated using the information in Appendix X1 , which shows the relationships between the Head Injury Criterion (HIC) scores of an impact and the probability of head injury. 1.9 This specification relates only to the impact attenuation properties of playground surfacing materials and does not address other factors that contribute to fall-related injuries. While it is believed that conformance with the requirements of this specification will reduce the risk of serious injury and death from falls, adherence to this specification will not prevent all injuries and deaths. 1.10 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.11 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. 1.12 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.
