HexArmor - Hand Safety Handbook

Test data is documented in accordance with the specific test method (for example, ASTM F1790-97) on a Cut Performance Data Sheet and includes testing date, name of technician conducting the test, test fabric description, calibration, data point measurements and cut resistance level assigned in correlation with the ANSI/ISEA 105 scale.

Comparing the ANSI/ISEA 105-2011 and ANSI/ISEA 105-2016 Standards A major difference between ANSI/ISEA 105 and ANSI/ISEA 105-2016 lies in how cut-resistance classifications are determined. In an effort to apply consistent meaning to the ratings for the end user ANSI/ISEA 105-2016 selected ASTM F2992-15 as the only accepted test method for measuring cut resistance, which uses the Tomodynamometer (TDM-100). However, the ANSI/ISEA 105 2011 version accepted the ASTM F1790 method along with its two additions: ASTM F1790-97 and ASTM F1790-05 which allows data from either of two different testing instruments: the Cut Protection Performance Tester (CPPT) or the TDM-100.

A second difference between the standards: As noted earlier, ANSI/ISEA105 measures cut resistance on a 1 to 5 point rating scale spanning from 200 grams to 3500 grams of cut resistance.

However, ANSI/ISEA 105-2016 provides an expanded 9-level cut resistance scale (A1-A9) that spans 200 grams to 6000 grams of cut resistance This addresses the gaps between cut levels found in ANSI/ISEA 105 and provides for more accurate identification of the protection offered and allows end users to more precisely identify a level of cut resistance that meets a specific need. The approach also models more closely the classification scale used in international standards. The graph shows the expanded cut resistance levels adopted by ANSI/ISEA 105-2016.
