ANSI/ISEA 138-2019 (Impact-Resistant Gloves)

Impact-Resistant Gloves

This american standard sets requirements of gloves designed to protect the knuckles and fingers from impact forces. 
The impact resistance is classified in level 1, 2 and 3, where level 1 equals the lowest level of perforce and level 3 equals the highest level of performance.

The test is performed by dropping a falling weight on the impact areas of the glove recording the force tranferred in kilonewtons (kN). Areas tested are knuckles at back of hand, fingers and thumb.
The weakest performance area defines the overall performance level of the glove and the protection level is given at the glove marking.
