VWR North Safety Hand Protection Chemical Resistance Guide- nitrile gloves breakthrough times ,• Breakthrough time (BT)is defined as the elapsed time between initial contact of the liquid chemical with the outside surface of the glove and the time at which the permeation rate reaches 0.1 mg/m2 /sec. WHEN BREAKTHROUGH OCCURS, THE GLOVE IS NO LONGER PROVIDING ADEQUATE PROTECTION. • Permeation rate (PR), measured in milligrams perGuide to Chemical-Resistant Best GlovesAll breakthrough times are normalized to the ASTM Re-quirements of 0.1 µg/cm2/min for the safest possible data. Such factors as temperature may accelerate the permeation and degradation of glove materials. ASTM F739, F1383 and EN 374 testing was performed as described in the standards at room temperature or 250 C. BEST GLOVES MEET YOUR NEEDS

Chemical gloves and breakthrough times - IOSH forums home

Jun 30, 2017·Manufacturers' published permeation breakthrough times are virtually meaningless in establishing the actual permeation breakthrough times when gloves are used. In the first place they are based on a laboratory test according to EN374, which is itself flawed as the test is done at room temperature as opposed to skin temperature.
