EN ISO 374-1: 2016 + A1:2018

The standard defines requirement the capability of gloves to protect the user against penetration, permeation and degradation by chemicals and microorganisms. It classifies three types of glove by level of protection (using test method EN16523-1:2015):

Marking of protective gloves:

  • Type A: Protective glove with permeation resistance of at least 30 minutes each for at least 6 test chemicals.
  • Type B: Protective glove with permeation resistance of at least 30 minutes each for at least 3 test chemicals.
  • Type C: Protective glove with permeation resistance of at least 10 minutes for at least 1 test chemical.
