Compared to the ANSI/ISEA 138-2019 standard, the EN388 dictates fairly limited testing criteria for impact protection. Under this standard, the same testing method is used as ANSI/ISEA, but only the back-of-hand material on the knuckles is tested, not the fingers or thumb.
Under this method:
l If the average transmitted force is less than or equal to 7kN, then the gloves receive a pass rating, indicated by the letter “P” on the EN388 standard shield
l If the average transmitted force is higher than 9kN, then the gloves receive a fail rating, indicated by the letter “F” on the EN388 standard shield
l A letter “X” indicates that a glove has not been tested
An example of the impact-resistant markings can be seen in the image below.
