U.S. Access Board A Summary of Accessibility Guidelines for Play Areas Page 22 Accessible Ground Surfaces Ground surfaces along accessible routes, clear floor or ground spaces, and maneuvering spaces, must comply with the American Society for Testing and Materials (ASTM) F 195199 Standard Specification for Determination of Accessibility to Surface Systems Under and Around Playground Equipment. This standard assesses the accessibility of a surface by measuring the work an individual must exert to propel a wheelchair across the surface. The standard includes tests of effort for both straight-ahead and turning movements, using a force wheel on a rehabilitation wheelchair as the measuring device. To meet the standard, the force required must be less than that which is required to propel the wheelchair up a ramp with a slope of 1:14. When selecting ground surfaces, operators should request information about compliance with the ASTM F 1292-04 standard. Accessible surfaces can include impact-attenuating tiles made of recycled rubber and engineered wood fiber that meet the ASTM requirements for accessibility and safety. The design can be created so safety is not compromised for individuals using the play area where both standards are applied. Accessible Surfaces Located In The Use Zone If located within the use zone, accessible ground surfaces must also be impact attenuating and meet ASTM F 1292-04 Standard Specification for Impact Attenuation of Surface Systems Under and Around Playground Equipment. The “use zone” is a ground level area beneath and immediately adjacent to a play structure or piece of equipment that is designated for unrestricted circulation around the equipment. It is predicted that a user would fall and land or exit the equipment on the surface of the use zone. The American Society for Testing and Materials (ASTM) has established safety standards for play areas, including resilient surfaces.
