Variability in force test results due to incorrect selection of grips and fixtures can be minimized by simply using the proper grips and fixtures. There are many universal solutions available, but will the universal grip or fixture hold up to the test?
Many factors come into play when choosing the right mounting hardware to ensure the specimen is properly aligned: it doesn’t slip in the grip, it has the correct force rating, it provides flexibility and interchangeability. A force tester equipped with the correct grips and grip faces for the application will provide test results true to the specimen tested. A specimen that breaks or slips in a grip due to incorrect grip faces will have a negative effect on the test results.
