The Universal Impact Tester Model 172RF was designed with the purpose of bending and stretching metal on which a coating was applied to provide valuable information on the elastic and adhesive characteristics of the coating. It provides a range of operating capabilities that match or exceed most existing instruments, such as powered elongation testers, cylindrical or conical mandrels, manual, powered and falling weight indenters.

Model 172RF meets Proposed Revision of TT-P-2756A - Polyurethane Coating: Self-Priming Topcoat, Low Volatile Organic Compounds (VOC).
Operating Instructions - The 172RF impact testers are essentially the same for all die, indenter punch and weight or combined ball weight-indenter punch combinations except for the GE impacter.
Coatings to be tested are applied to cleaned thin metal panels, after the coating to be tested is properly cured and ready for test.
Normal procedure is to place the test panel between the impact tester indenter punch and the die with the coating facing downward against the die. (Some investigators have gained important information on coating properties by placing the panel in the apparatus with the coating facing upward and in contact with the indenter punch).
