What tests have been carried out to prove the Hyperlite s durability?
A7 The hyperbaric stretcher has been subjected to the following tests: 1. Hydrostatic Burst Tests: The hyperbaric stretcher fails on average at 14.7 bars, 147 msw, 483 fsw), giving a safety factor in excess of 6:1. 2. Drop Test: The hyperbaric stretcher was weighted with an internal litter and 90 kg. (200 lb.) of bagged water and dropped at an angle of 45 degrees on to a rough concrete surface from 3 feet (90cms) above the ground. No damage or pressure loss took place. 3. Cyclic Test: The hyperbaric stretcher was cycled 17,000 times from atmospheric to maximum working pressure. It did not fail. 4. Folding Tests, Hot and Cold Storage and Inflation Tests, Solar Radiation and Salt Fog Resistance and Vibration Tests have been satisfactorily tested by the Defence Research Agency, Alverstoke UK for the Ministry of Defence UK, and/or by the Wyle Laboratories in Huntsville AL on behalf of the US Navy and US Air Force, who are accepting the Hyperlite as being suitable for military application.
