CUT RESISTANT GLOVE – WHAT DOES THIS MEAN
The Standard applies to protective gloves and refers to their resistance to abrasion, cut, tear, puncture and impact. Key changes to the Standard include an additional cut test (ISO13997) if the traditional cut test (Coupe Test) fails while a non-compulsory impact resistance test has been added. ProChoice Safety Gear supports any Standards reform that improves accuracy of testing results and ultimately safety in the workplace. We have long understood the shortcomings in the Coupe test – outlined below – and resultantly, prior to the updated to EN388, were voluntarily testing our gloves to the American (ANSI) Standards to ensure maximum protection.
COUP CUT TEST
As fabrics – particularly those with cut resistance – have become more technically advanced in protecting against cuts and lacerations, limitations to the traditional methods for measuring cut resistance (Coupe Test) have been identified. The Coupe Test measures cut resistance by recording the number of cycles it takes to cut through a glove material at a constant speed and pressure when compared to a cotton reference. A rating of five (5) is the highest score a glove can receive using the Coupe Test. Many cut resistant fabrics have evolved significantly from when the EN388 Standard was originally written, to the point where these fabrics can easily withstand 20 or more blade cycles of the Coupe Test. In fact, many of these fabrics will blunt the Coupe Test blade, further compromising the accuracy of test results.
The new Standard, EN388:2016 states that if the Coupe Test blade is deemed “blunt” or the test fabric is not penetrated after 60 cycles, the Coupe Test is abandoned and ISO 13997 applies.
IS0 13997 CUT TEST
ISO 13997 measures the amount of pressure required to make an incision in the test fabric over a 20mm travel distance using a razorblade. Performance is rated with the letters A to F, depending on resistance to pressure, which is measured in Newtons (N). “F” is the maximum cut resistance of the ISO 13997 test and is awarded to any fabric that achieves a cut resistance equal to or greater than 30N or approximately 3.06kg. The ISO 13997 Cut Test is commonly referred to as a “real world” cut test because of its ability to measure cut force, which is widely considered a more relevant metric in workplace situations when a cut risk is present.
