Standardized test and measurement methods based on the VDI 2248 guideline
Sheet 3 "Test and Measurement Methods", presented in this paper, describes methods for determining the mechanical, physical and, in particular, functional characteristics of SMA. With regard to the mechanical characteristics, the tensile test is presented as the most important measuring method and the special features of the testing of SMAs are pointed out. To determine the transformation temperatures, calorimetric or bending test methods are explained. Special test methods have been developed for the functional examination, which are also described in sheet 3. A table provides further assistance in selecting the measuring methods. In particular, the areas of quality assurance and materials testing will find valuable information in this guideline sheet. In addition, a certification is in the planning, which is to ensure the guideline-compliant testing of SMAs.
