The resistance of a protective glove material to permeation by a solid or liquid chemical is determined by
measuring the breakthrough time of the chemical through the glove material.
In the permeation test apparatus the glove material separates the test chemical from the collecting medium.
The collecting medium, which can be a gas, a liquid or a solid, is analysed quantitatively for its concentration of the
chemical and thereby the amount of that chemical that has permeated the barrier as a function of time after its
initial contact with the glove material.
