Several methods exist to model the behavior of materials to resist sharp edges and cuts. The primary instrument used for standards in personal protective equipment is the tomodynamometer. This machine is used in worldwide standards and is a powerful tool in modeling cut resistance. Use of this equipment, however, does present some challenges. The first challenge is calibration. Although the manufacturer gives instructions on calibration, no external methods are available to verify calibration. The first section of this paper looks at the existing methods of calibration, draws on existing data to investigate effectiveness, and proposes a new methodology to improve precision and reduce machine bias. The second challenge in measuring cut resistance is the issue of consistency. Although precision statements can be useful in estimating machine bias and its effect on results, the reasons for inconsistency of test results have not been fully explained. The second section of this paper will investigate various theories of consistency issues in cut resistance, in particular various properties of fibers and textiles. Microscopic investigations using the tomodynamometer will look at performance of various materials under testing conditions. This should provide guidance about how to reduce consistency issues with the test standards in question. Finally, the third section will look at possible future solutions that might best use the tomodynamometer to model cut-resistance behavior. Modifications to the equipment that might improve testing efficiency and performance are compared and investigated. Modifications to the test methodology also are discussed, as well as possible changes to consumables used during testing.
