Protective gloves against dangerous chemicals and micro-organisms.
Part 1: Terminology and performance requirements for chemical risks
 
Gloves against chemicals must resist against penetration (this is a movement on a non-molecular level  of a chemical through materials, seams, pinholes, or other imperfections in a protective glove material) and permeation (this is a process which a chemical moves through a protective glove material on a molecular level).
 
   Class            Breakthrough time
 
 1     > 10 minutes
 2     > 30 minutes
 3     > 60 minutes
 4     > 120 minutes
 5    > 240 minutes
 6     > 480 minutes
 
3 types of gloves are defined according to the number of chemicals tested on a list of 18, and the passage time.


TYPE Breakthrough time
      A        ≥ 30 min for at least 6 products of the list (see below)
B  ≥ 30 min for at least 3 products of the list (see below)
C      ≥ 10 min for at least 1 product of the list (see below)
 
18 chemicals are eligible to perform the test.
Each chemical corresponds to a letter.
