Gloves as this kind would be disastrous to the wearers if no quality test has even been made. Presently, there are many kinds of domestic and international cut proof and quality inspection systems. Specifically, this part would elaborate two major quality inspection system: EN 388 and ANSI.
- EN 388 Quality Inspection in Europe
One of the most trustworthy and commonly- practiced one is EU EN388 for working gloves, which is passed by the European Committee for Standardization in July 2nd, 2003.
On the basis of the general standard EN420, this standard stipulates the technical requirements, test methods, marks and instructions for the mechanical hazard protection for labor protective gloves. The mechanical hazard refers to the dangers that may come along with friction, blade cutting, tearing and stabbing. To prove the standard of mechanical hazard, the cut-proof gloves should pass four sub-relative tests:
- Abrasion resistance (number of rounds that glove material resistant to repeated friction);
- Cutting resistance (the number of times that the gloves materials resist cutting objects);
- Tearing resistance ( how much power is needed to tear a pre-arranged hole on the gloves);
- Stabbing resistance (how much power is needed for a standard spike to stab through the palm of the gloves).
Specifically, the ranking is made based on the following specifications.
|Abrasion resistance (unit: round)
|Cutting resistance(unit: times)
|Tearing resistance (unit: newton )
|Stabbing resistance (Unit: newton)
Specifically, EN 388 quality inspection would take respective method to deal with the above four tests and demonstrate the results of them with different marks of mechanical hazard, which then express the performance ranking of the gloves in terms of the four critical aspects. Generally, the higher the level is, the better the gloves are. All the inspections are processed within a controlled lab.
- ANSI Quality Inspection in America
Of course, some other authorized quality inspection system also shines in the market. This includes the standard practiced by the testing agency known as American National Standards Institute (ANSI). The level of cut resistance is judged by the performance of four factors: strength, hardness, lubricity and rolling action, which differs from the four factors of EN 388. Specifically, An ANSI level is determined by how much weight is needed to cut through a given material with 25 mm of blade travel.
You may check the following chart to see specific specifications for each level.

||Greater than 500
||Greater than 1000
||Greater than 1500
||Greater than 2200
||Greater than 3000
||Greater than 4000
