EURO PROTECTION • PROTECTIVE GLOVES
Protective gloves protect the hand or even a part of the arm (depending on the length of the cuffs) against certain risks.
The description of the technical requirements for personal protective equipment are included in the respective EN standards
of which the following apply to gloves in particular:
EN 374
Protective gloves against microorganisms and chemical risks
EN 388
Protective gloves against mechanical risks
EN 407
Protective gloves against thermal risk
EN 421
Protective gloves against ionizing radiation
EN 420

Protective gloves against electrical voltage
EN 420 general requirements for gloves
- correct pH value (3,5< ph >9,5)
- dexterity of the hand (5 performance levels)
- water vapor transmission (min. 5 mg/cm
