Cut levels explained Cut resistance is often the number-one characteristic considered in selecting hand PPE, as cuts, abrasions, and punctures are among the most common types of hand injuries sustained in the workplace. There are two testing and classification standards that exist to measure cut resistance: ANSI/ISEA 105-2016 and EN 388. Understanding the ANSI/ISEA 105 American national standard for hand protection The ANSI/ISEA 105-2016 standard has established ASTM F2992-15 as the test method for measuring cut resistance and offers a 9-level scale (expressed as A1-A9) based on the gram score. This scale spans from 200 grams to 6,000 grams of cut resistance. Prior to 2016, this standard (ANSI/ISEA 105-2011) used a 1-5 scale but was updated to allow for more accurate identification of protection in PPE. Cut Resistance Rating System: What’s Changing

ANSI/ISEA 105 cut resistance testing To measure scoring, the Tomodynamometer Test Method (TDM-100) is used based on the ASTM F2992-15. The TDM-100 determines the amount of weight, measured in grams, necessary for a blade to achieve cut-through of PPE material. Materials are tested under three varied weights to achieve five cut-through distances(mm) within each set of distance ranges. All cuts are made in the same direction at approximately the length of 20mm. After each cut, a new blade is used, and weight (in grams) is
