REGULATION 12 SCHEDULE 3 3.4.2 Resistance to Compression Loading When tested in accordance with the procedures specified in Section 4.4.6 the Device shall be deemed to have failed if it ruptures under loads less than 1.001kN. If a Device ruptures under loads of between 1kN and 2.5kN, then it must be assessed for failure as detailed in Section 4.3.2. If the Device does not rupture under a load of 2.5kN then the Device will be deemed to have passed the dynamic loading requirements. If, at any point a Device fails a testing requirement, the whole testing protocol must be stopped and the Device design determined to be noncompliant. 4. Test Methods and Procedures Compliance 4.1 Sampling Two distinct test pieces are required: • Empty Device casings • Full Devices, that is a Device which includes all parts required to function properly and as intended to be worn by an athlete. A total of 20 empty Device casings and 5 full Devices are required for testing. It is recommended that all empty Devices are tested for all conditions prior to the full Devices being tested. 4.2 Conditioning of Specimens • Test specimens must be in a new, un-used and un-tested condition. • The test specimen must be prepared by being conditioned for 12 hours at 0±2°C or 23±2°C depending on the test requirements and at an ambient humidity. 4.3 Testing Conditions 4.3.1 Rupture A Device will be deemed to have ruptured if the casing changes shape permanently as a result of any of the modes: • Fractures – When the surface of the Device cracks or fractures resulting in any part protruding beyond the level of the original (pretest) surface. • Shatters – When one or more fragments are detached from the body of a Device into one or multiple small, sharp pieces.
