【国外标准】 Standard Specification for Shock Attenuation Properties of Fencing Surfaces (Withdrawn 2016)

This specification covers shock absorption properties of fencing surfaces as measured by a drop test. The minimum performance standard for shock absorption is defined. Guidelines for other features and properties of fencing surfaces are described. The types of fencing surfaces covered by this specification are as follows: Type I—concrete; Type II—covered concrete (for example, with linoleum tiles, or rubber runners); Type III—hardwood on concrete; Type IV—plywood on concrete; Type V—hardwood on floor joists; Type VI—plywood on hardwood; Type VII—raised plywood; Type VIII—other surfaces such as synthetic gym floors or recycled rubber composite; Type IX—rubber runners (strips) on various flooring types, except concrete; and Type X—copper or steel fencing strips on various flooring types, except concrete. Materials shall be tested and the individual grades shall conform to specified values of shock attenuation, stability, and shoe-to-surface interface.1.1 This specification covers shock absorption properties of fencing surfaces as measured by a drop test. The minimum performance standard for shock absorption is defined. Guidelines for other features and properties of fencing surfaces are described.1.2 The values stated in SI units are to be regarded as the standard.1.3 This specification does not purport to address all the safety concerns, if any, associated with fencing surfaces and will not prevent all surface-related injuries. It is the responsibility of the user of the surfaces to establish appropriate safety and health practices, including, but not limited to, foot movement, footwear (shoes), and training practices. Specific precautionary statements are given in 5.3.
