Chemical Permeation Testing | ChemDefend

The average elapsed time between initial contact of the chemical with the outside surface of the fabric and the time at which the chemical is detected at the inside surface of the fabric at a permeation rate of 1.0 μg/cm2 / min. Thus the breakthrough time is ‘normalized’ as it is independent of the analyser sensitivity. Here the lowest BT is recorded. A normalized breakthrough time of >480 minutes means …
