Guidelines for the right choice

Regulations, markings and standards for protective gloves

manual

Technical characteristics of gloves are determined by European standards. They are indicated by pictograms, to which numbers are added to clarify the level of protection. 

EN 420 - General requirements for protective gloves

This icon means you need to read the instruction leaflet

EN 420 defines general requirements for most protective gloves: 

ergonomics, material (neutral pH balance, the amount of hexavalent chromium and the absence of impurities that cause allergies), harmlessness and comfort (size), practicality, penetration and absorption of moisture;

if antistatic performance is required, the glove is tested according to EN 1149 - 1, -2, 3. Pictograms should not be used, but additional information about laboratory tests should be added; numbering of protection levels: 1 - minimal, 2 - good, 3 - very good, 
4 or more - excellent, 0 - does not provide protection, X - the glove has not been tested; information on usage and protection levels is given below.

The choice of the size of gloves according to the length of the hand and its area

EN 374 - Protection against chemicals and micro-organisms 

This pictogram means the following property - protection against microorganisms 

This pictogram is used for chemical gloves that withstand more than 30 minutes of 3 chemicals from the list below (e.g. EJL) 

 Glove size  0 1 2 3 4 5 6
 minutes  ≤ 10     > 10  > 30    > 60     > 120     > 240    > 480   
A   methanol  G   diethylamine
B   Acetone H  Tetrohydrofuran
C   Acetonitrile   ethyl acetate
D  dichloromethane J   n - Heptane
E   carbon disulfide K   Caustic soda solution 40%
F   Toluene L   Sulfuric acid solution 96%

This pictogram indicates that the gloves have been tested but only protect against chemicals for a short period of up to 30 minutes.
