Nitrile gloves, as to understand their diversity?

Nitrile working gloves, as to understand their diversity?
Currently, the market has a lot of work gloves coated with nitrile from different manufacturers.

In the EU, gloves sold 2 categories:
A. Lowest 2.Vysshaya
Assigned to the second glove (highest) category only after successful completion of testing. The test results are applied to the product.
If the glove do not have numbers, characterizing the degree of protection, so these gloves are the first category.

In accordance with European standard EN388 mechanical stability above all we must pay attention to the markings. More precisely, the presence of 4-digit, standing near the sign "protection from mechanical damage," characterizing the degree of protection to: abrasion, cut, stretch, puncture.

The protective properties of mechanical stress are indicated by EN388, and four digits underneath, denoting:


The values ​​of the exponent 1 2 3 4 5
A Abrasion (cycles) 100 500 2000 800 -
Cuts in the (number) 1.2 2.5 5.0 10.0 20.0
With the gap (Newton) 10 25 50 75 -
Punctures D (Newton) 20 60 100 150 -

The higher the number, the greater the protection for this indicator.

The protective properties of chemical resistance are indicated by an icon EN347, without the numbers below. Under the symbol marks indicate basic chemicals from which the defend gloves.

The icon marks the protective properties of working gloves.
