Cut resistance is graded on a scale from A to F, with F being the highest level of protection. This protection is graded according to the new TDM (ISO 13997) test method, included in EN 388:2016, and specifies how much force is required to cut through the material. Previous labeling in accordance with EN 388:2003 used cut-resistance grades 3–5, which cannot be translated directly to A–F.
Puncture protection, or rather puncturing of material, is graded on a scale of 1–4, with 4 being the highest level of protection in accordance with EN-388.
To ensure that you select the appropriate form and level of protection, a risk assessment must be carried out. If you are looking for puncture protection from needles or sharp-tipped objects, you should keep your eye out for the following American standard: ASTM 2878.
