The highest protection level for cut-resistant gloves is level 5, which represents the strongest cut resistance in both the EU EN388 standard and the Chinese national standard.

Cut-resistant glove level classification standard

EU EN388 standard.
It uses a 1-5 level classification, with level 5 being the highest protection level. It needs to pass the tungsten steel rotary cutter test, and the cutting index is ≥20.
The new standard EN388:2016 adds A-F sub-level ratings, but the highest cut resistance level is still level 5.
Chinese national standard (GB24541-2009).
It is also divided into 5 levels, with level 5 corresponding to the highest protection capability, aligning with the EU standard.
US standard.
It uses an A1-A9 grading system, which has no direct correspondence with the EU level 5 standard.
Core characteristics of level 5 cut-resistant gloves

Protective capability: Can withstand ≥20N of cutting force, and can even briefly resist chainsaw impact.
Material technology: Uses stainless steel wire, HPPE fiber + glass fiber or Kevlar composite materials, combining wear resistance and flexibility.
Application scenarios: Suitable for high-risk industries such as metal processing, glass cutting, and fire rescue.
Selection suggestions

Matching work risks: Levels 1-3 can be selected for home use, while levels 3-5 are recommended for industrial scenarios.
Pay attention to certification marks: Regular products should be marked with the EN388 shield logo and protection level.
Consider comprehensive performance: Although level 5 gloves offer the strongest protection, the flexibility, breathability, and other practical usage needs should be balanced.
