EN 13594:2015

The EN 13594:2015 standard demands only that the knuckles be tested for impact absorption.

What's the Difference

ANSI/ISEA 138-2019

ANSI/ISEA 138-2019 institutes testing of knuckles as well as finger protection. On the middle and little fingers the testing area is measured 5 cm from fingertip. On the index, ring finger and thumb, testing area is 2.5 cm from fingertip.

ANSI/ISEA 138-2019 - Where To Test?

ANSI/ISEA Testing Locations
Three individual testers

Three different individuals with appropriately sized hands try on the glove.

Three different knuckle points

While firmly gripping a cylindrical bar, a point is made where each knuckle is most prominent.

Triangle testing area

A triangle is then drawn to connect the points from all three individuals. The center of these triangles become the test area.

ANSI Impact Standard Absorption Graph

Temperature Matters

Impact protection made of TPU, TPR and other polyurethane mixtures can be modified from product to product. While the ANSI/ISEA 138-2019 standard identifies the ability of a glove to withstand impact and protect hands under ideal conditions, variations in temperature can greatly affect the effectiveness of impact protection.

Internal evaluation should be done for each unique situation to identify the effectiveness of a glove at absorbing impact.
