Are ANSI and CE EN 388 cut levels the same?
Absolutely not. The two levels are achieved with completely different testing methods and are therefore not interchangeable. Be careful that you know which cut level is shown when you’re purchasing gloves. Gloves rated cut level 3 with EN 388 might only be ANSI cut level 1.
What testing method does ANSI/ISEA 105-2011 use to determine cut resistance?
Either a Cut Protection Performance Test (CPPT) or TDM 100 Cut Test Machine can be used. The methods are very similar and both measure the amount of force (in grams) that it takes to cut through glove material for a specified length. When testing per ASTM F1790-97 the cut level is determined after a blade pass distance of 25mm. When testing per ASTM F1790-05 the cut level is determined after a blade pass distance of 20mm.
Does ANSI/ISEA 105-2011 specify abrasion resistance?
Yes. Rotary abrasion tests like the Taber Abrasion Test determine how many cycles it takes to wear through a glove coating or yarn with a 500g or 1000g load. ASTM D3389-05 outlines testing of coated glove fabrics. ASTM D3884-05 outlines testing for uncoated fabrics.
What testing method is used for CE EN 388?
The Coup Test utilizes a circular blade with a fixed load of 500g that moves back and forth until it cuts through the fabric sample. A cotton canvas is alternately cut and serves as a reference material. The cut resistance level is the ratio of cycles needed to cut through the test sample as compared to the reference material.
Does EN 388 measure low level and antlestslots.com high level cut resistant gloves with equal accuracy?
Not always. The Coup Test is best used when testing lower level cut-resistant gloves because high cut- resistant gloves can dull the blade, which affects the results.
What attributes does EN 388 illustrate?
The EN 388 rating doesn’t just show cut resistance. The four-digit rating also shows abrasion resistance, tear resistance, and puncture resistance.
How do glove coatings affect cut resistance?
Most coatings add to abrasion resistance. However, extremely thin coatings can actually negatively affect cut resistance.
What is the most accurate way to determine the cut resistance features of a glove?
The CPPT gram weight for a glove is a more thorough indication of cut resistance than just the performance level. Keep in mind that a glove that achieves a 995 (Level 2) on the CPPT provides nearly the same cut resistance as glove that achieves a 1,010 (Level 3), even though they have different performance levels.
What are the best materials for cut resistance?
There are dozens of materials to choose from. Kevlar offers good cut resistance and excellent heat resistance. Dyneema, Spectra and HPPE are breathable and soft, but still offer good cut resistance. Stainless steel and fiberglass strands are commonly woven into glove material like Kevlar and Spectra to greatly enhance cut resistance. Engineered Fibers are materials like SuperFabric provide extremely high cut resistance but good comfort. Steel mesh offers excellent blade cut resistance. Keep in mind the cut level needed for your application and the desired comfort level when choosing a glove material.
