EN388 vs ANSI

What's the difference?

A summary of the standards

EN 388: 2016 is the European Standard governing gloves that provide protection against mechanical risks. 

ANSI/ISEA stands for American National Standards Institute / International Safety Equipment Association.  This is a US Standard only and not a government regulation, which uses a mix of ASTM (American Society for Testing and Materials) and EN (European Norm) methods.

With the introduction of the TDM cut test to the EN388:2016 revised standard, ANSI and EN388 have become much closer aligned.

 

EN388:2016

The EN388 standard now consists of two cut resistant values, using two different testing methods. The first is the Coupe Test using a circular blade that moves back and forth under 5N contact force until it cuts through the material. The blade cut resistancy is stated on a 0-5 scale based on the number of rotations it takes to cut through the sample, using a standard canvas control material before and after to take the sharpness of the blade into consideration.

However, highly cut resistant materials can dull the blade in the Coup Test and cause inconsistencies. Due to this, EN388 added a second test required for high cut materials: the ISO 13997 TDM test.

 

TDM cut test: How it works

This cut test determines the resistance of a safety glove by applying the sample fabric from the palm with great force in a single movement.

To this end, a sharp-edged blade is dragged over the sample fabric once. This allows the accurate calculation of the minimum force required to cut the sample material at a thickness of 20mm. 

 

The difference

The test works exactly the same for both standards but it’s the way they’re measured that differs.  While the A1-A9 scale is comparable to the EN388 A-F levels, ANSI/ISEA extends their scale by three levels to 6000 grams to report high cut materials more accurately.
