【国外标准】 Standard Test Method for Playground Surface Impact Testing in Laboratory at Specified Test Height

5.1 The purpose of this test method is to determine the shock absorption properties of a playground surface at a specific impact height in order to evaluate a particular playground surfacing system using the g-max and HIC criteria as outlined in Specification F1292. This will allow the owner/operator to specify certain minimums that they desire for their playground surface in relation to their playground equipment fall height and can be confirmed in the field after installation or throughout the functional life for the surface system utilizing Test Method F3313.5.2 This test method is to be used as a reference for specifying the impact attenuation performance of playground surfaces and the height from which they are tested.1.1 This test method covers all playground surfaces to be tested in a laboratory setting at a specific drop height established by the manufacturer of the playground surface to determine shock absorption properties at the specified height above the surface and to evaluate surfaces based on their Gmax and HIC values described in Specification F1292.NOTE 1: This test method is not intended to replace Specification F1292 for critical fall height (CFH) testing but to provide more information to either the manufacturer of the surface or the owner/operator purchasing the surface.NOTE 2: This test method informs the owner/operator of the impact attenuating performance of the surfacing system at the specified height used in the test.1.2 This test method is specific to surfacing used in conjunction with playground equipment, such as that described in Specifications F1148, F1487, F1918, and CSA Z614.1.3 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.1.4 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.
