This report describes an investigation into the temperature sensitivity and repeatability of test results obtained using a Cooper wheel tracking device. One set of specimens was tested at the standard temperature (60 Degrees Celsius) and two other sets of specimens were tested at 55 Degrees Celsius and 65 Degrees Celsius respectively. Results from repetitions at each test temperature showed a large variation (poor repeatability). From a careful observation of the operation of the test, a number of fundamental causes (e.g. test set-up, equipment design, specimen size etc.) were identified. Possible solutions for the observed problems are suggested.
