EN 388 vs ANSI/ISEA 138
Previously, the EN 388 Standard was the only measurement of impact protection recorded to date that could be referenced. The European standard impact test is based on the EN13594 2015 Standard for Protective gloves for motorcycle riders. The test method is similar, but only test the knuckle impact (excluding the fingers). The EN 388 Standard classifies impact protection with a letter representation: P represents Pass, F represents Fail and X represents Not Tested. If the average transmitted force is less than or equal to 7kN, then the gloves will receive a Level 1 P, Pass rating. If the average transmitted force is higher than 9kN, then the gloves will receive a Level 0 F, Fail rating.
The new ANSI/ISEA 138-2019 standard breaks down this letter representation into a numerical range of mean transmitted forces. This allows different impact resistant applications to precisely match up to the correct numerical value, or protection level needed for the job. This new ANSI/ISEA 138 standard measures higher protection values than the EN388 2016 testing.
