Select grips and fixtures based on the maximum force you expect to apply in the test, while staying within the UTM frame’s rated capacity. In practice, the safe working limit is set by the lowest-rated component in the load train, including the grip or fixture, adapters, and the load cell, so the accessory should be chosen to comfortably handle your peak load for that method.

A simple way to size the hardware is to confirm these items up front:

• Your highest expected test force for the material, geometry, and method
• Whether the setup is for tensile, compression, flexural, shear, peel, or puncture loading
• Whether your UTM is electromechanical or servo-hydraulic, and which accessory family fits that style

Capacity is only part of the match. For consistent results, prioritize fixtures that maintain alignment and control slip or specimen damage, for example self-tightening designs and interchangeable jaw faces such as smooth, serrated, or rubber-coated options.
