EN ISO 374-5
EN 374-1: 2016
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 |
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 breakthrough time.
TYPE |
Breakthrough |
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 products of the list (see below) |
18 chemicals are eligible to perform the test.
Each chemical corresponds to a letter.

Part 4: Determination of resistance to degradation by chemicals
Degradation levels indicate change in puncture resistance of gloves after exposure to the chemical.
