This research paper will present and analyze selected testing of wax patterns - bending strength test, test of resistance to creep and penetration hardness test. Evaluation of these tests will be carried out in terms of the shape accuracy of wax patterns. Additionally, statistical evaluation will be carried out of relationships between selected parameters of previously mentioned tests. Standard bending tests will be statistically evaluated and compared with two other test methods conducted on corresponding patterns. Particular attention will be given to creep resistance, which is a very useful test method for assessing changes in the shape of complex patterns in the function of time and temperature. At the same time an evaluation of hardness tests of wax patterns will be carried out with usage of appropriate samples or by direct examination of the production patterns.
