chemicals according to EN 943-2:2002
For European approval, the tests against the concentrated

wetting/coverage of the test samples.
The classification for testing the resistance to the permeation
of chemicals is given in accordance with EN 943-1:2015 as
follows:
Class 1: >10 minutes
Class 2: >30 minutes
Class 3: >60 minutes
Class 4: >120 minutes

conditions. The chemical protective suit period of use can
depend on several factors, including the concentration and
state of matter of the contaminant and the ambient conditions.
