The ASTM D6537-00 (2021) standard provides an instrumented method of Encasement impact testing for obtaining performance data on Encasement under impact. This method quantifies the ability of Encasement systems to protect against transport impacts or impacts, helping to determine the level of protection required for Encasement or to optimize cushion design. The standard covers impact testing using actual or simulated product Encasement systems, excluding Miscellaneous Impact Measuring methods such as high-speed video. Data can be used to specify transport and handling methods to ensure the safety of Encasement products. Users need to establish appropriate safety measures and determine relevant regulatory restrictions before use.
