SCHEDULE 2 REGULATION 12 Test D – Fitting of replaceable studs/cleats If the stud/cleat is replaceable then it should be fixed to, and detach from, the boot sole at least ten times according to the manufacturer’s instructions and using the tools provided, if any. Apply a torque or force level just over and above what might be considered ‘reasonable’ for a powerful rugby player. For example, a reasonable torque to apply to conventional screw-in studs is 1.5 N.m. Inspect for any sign of damage that might increase the risk of causing injury in wear. Where such damage occurs, tests could be carried out according to tests A and B. Test E – Wear simulation The principle of this test should be based on replicating the biomechanics of gait such that it reproduces the correct contact angles and loads between the boot and ground that occur in wear. The test cycle commences with the heel striking the test floor at a predetermined angle, and the vertical load increasing as the ‘leg’ rolls forward over the shoeground contact point, eventually transferring contact to the forepart of the shoe and finally toe-off. The vertical load achieved during the cycle should be at least 120% bodyweight. The floor used should replicate an abrasive, man-made surface such as concrete or asphalt that might be expected to be found around rugby pitches or in clubhouses. Alternatively simple trials, whereby players walk or run for say 400 m on a an abrasive, man-made surface, would suffice Inspect each stud/cleat for any sign of damage that might increase the risk of causing injury in wear. Where such damage occurs, tests could be carried out according to tests A and B. Last update: 14 January, 2015 222
