The 2016 Cut Resistance Ratings Standard
ANSI is the North American ANSI/ISEA 105-2011 standard for Protective Gloves Against Mechanical Risks. In 2016, the standard changed to create consistency between the ANSI and EN388 test methods which is called the ASTM F2992-15. The 2016 revision of the Ansi/ISEA 105 standard is a more expanded level of classification of cut resistance. The results of the ANSI ASTM F2992-15 cut test method will feature 9 levels of cut resistance, which will be expressed as A1-A9. It has smaller increments between levels. Additional levels have also been added to the higher end of the cut resistance scale to account for new cut resistant materials and technologies coming on to the market.
You can see in the first chart below how the old ANSI rating system compares to the revised ANSI standard. In the second chart you can see how the new ANSI standard with correlate to the new EN388 ISO 13997 rating.
