The report documents the procedures used to commission a Cooper wheel tracking apparatus. Practical issues are discussed with emphasis on achieving a repeatable outcome. This involved checking the accuracy of the loading system and the deformation measurement system. Temperature is a large factor affecting the test outcome and the spatial variation within the temperature controlled cabinet was assessed. In addition, the temperature of test samples both on the testing table and on the storage shelf were monitored to derive procedures that ensure that the core temperature during testing was 60 Degrees Celsius.
