ASTM F0355-23 - Standard Test Method for Impact Attenuation of Playing Surface Systems, Other Protective Sport Systems, and Materials Used for Athletics, Recreation and Play

1.1 This test method measures the impact attenuation of surface systems and materials, specifically the peak impact acceleration (“impact shock”) and calculates the Head Injury Criteria produced under prescribed impact conditions.

1.2 This test method is applicable to surface systems intended to provide impact attenuation, made of naturally occurring or synthetic materials.

1.3 This test method is applicable to impact attenuating mats and padding used in sports facilities, including, but not limited to: stadium wall padding, gymnastic mats, wrestling mats, turf playing systems, pole vault landing systems, and playground protective surfacing.

1.4 This test method is used to measure the impact attenuation of materials and components used as protective padding on trampoline frames, goal posts, etc., provided the material or component can be tested separately from the equipment to which it is attached.

1.5 Without modifications, this test method shall not be used to test materials and components that are attached to structures or equipment or finished products, unless the impact attenuation of the whole system is of interest.

1.6 While it is widely believed that lower values for impact attenuation can reduce the severity of impact-related injuries, the relationships between the results of this test method and specific injury risk are within automotive testing data.

1.7 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.8 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.

1.9 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.
