In order to correctly test your specimen, you have to ensure that the only stress that it is under is the stress 
of the load you are testing. If the specimen is held too loosely or, perhaps worse, too tightly, then other forces will be acting on it that your testing procedure won’t be accounting for.
Different types of testing will require different fixturing, and the material being tested will also play a big part in the kind of grip that you use. Ceramics, metals, plastics, and foams, all have different needs.
Given the wide variety of materials you need to test, and the various types of test that you’ll be running on them, TestResources offers a number of different grips that allow you to hold your specimens securely without subjecting them to undue stress that will skew your results. This might be especially important when your test subjects are small and/or fragile already.
