In recent years, rapid technology advancement allowed manufacturers to create more sophisticated yarns that improved glove performance significantly. Cut-resistant gloves and sleeves are designed to protect hands and arms from direct contact with sharp objects made of metal, ceramic, or glass. Cut level protection is ensured by a combination of the material’s composition and thickness. The level of cut protection can be increased by using high-performance materials (Kevlar, Dyneema); composite yarns made with fiberglass, steel, or synthetic materials; by increasing material’s weight measured in ounces per square yard.
The benefit of using heavier gloves is that they provide extra protection against cuts, puncture, and abrasion, as well as provide superior durability. Lightweight glove styles now offer more dexterity and reduce hand fatigue. The advantage of coated gloves is their enhanced grip capability as well as high levels of cut protection. Today PPE users have a wide variety of options to choose from, and new standards can help facilitate the decision- making process.
What Has Changed?
The American National Standards Institute has released a new ANSI/ISEA 105-2016 Standard. The changes involve the Cut Level Rating Scale and the Method of Testing.
- A new, expanded 9-Level Classification for cut-resistance reduces gaps between cut levels 4 and 5, and expands the range of protection levels for the cut resistant gloves with the highest gram scores;
- The new ASTM F2992-15 Standard allows only a TDM-100 machine to be used for glove testing. This makes it more reproducible, and they have taken into account the dulling of the blade that occurs during testing and required a new blade is used for each cut.
The addition of new ANSI/ISEA levels will allow safety glove users to make a more informed decision about the level of protection that they need for different types of projects. Applications include: A1 - light material handling without sharp edges; A2-A3 - small parts handling with sharp edges, forestry, packaging, warehouse; A4-A5 - appliance manufacturing, pulp and paper, bottle and light glass handling, canning, dry walling, electrical, carpet installation, HVAC, metal handling, metal recycling, automotive assembly, metal fabrication; A6-A9 - sharp metal stamping, glass and window manufacturing, pulp and paper (changing slitter blades), recycling plant and sorting, food preparation and processing, meat processing, aerospace industry.
