SCHEDULE 2 REGULATION 12 PERFORMANCE TESTS – OPTIONAL The principles for five tests are suggested: Test A – Skin Glancing/Raking test Test B – Skin Stamping test Test C – Stud/cleat Impact test Test D – Fitting of replaceable studs/cleats Test E – Wear simulation Tests A and B provide a direct method of assessing a stud/cleat’s propensity to cause injury through glancing, raking or stamping mechanisms. Tests C and D assess the mechanical strength of studs/cleats and their attachment to the boot and thereby assess the risk of product failure resulting in a stud/cleat or boot sole becoming damaged and creating a potential hazard. Test E provides a means of assessing how studs/cleats may change inservice due to wear and indicate whether or not there is an increase risk of injury. A schematic illustration of the principle of each test is given below. For tests A and B a suitable human flesh simulant is required comprising an artificial skin backed with a thick deformable muscle-like material. For example, a 1.5 mm thick poromeric shoe upper material having relatively low abrasion resistant may be used an artificial skin combined with gelatine, moulded into suitable form, as the deformable substrate. The performance criterion for tests A and B is that the stud/cleat be evaluated should cause no greater damage to the artificial skin than the reference stud/cleat defined in Figure 1 above.
