NOTE: Permeation test data relates to "Normalised Breakthrough" which measures the time for the permeation rate to reach a specific speed (In CE EN 6529 testing, 1.0µg/min/cm2 and in US ASTM F739 testing, 0.1µg/min/cm2). This does not indicate when the chemical first breaks through the fabric and is not an indication of how long the suit can be safely used as the chemical may have permeated through the fabric before the Normalised Breakthrough time. This might be critical in cases of chemicals with high toxicity.
