This information is based upon technical data that DuPont believes to be reliable. It is subject to revision as additional knowledge and experience are gained. DuPont makes no guarantee of results and assumes no obligation or liability in connection with this information. It is the user s responsibility to determine the level of toxicity and the proper personal protective equipment needed. The information set forth herein reflects laboratory performance of fabrics, not complete garments, under controlled conditions. It is intended for informational use by persons having technical skill for evaluation under their specific end-use conditions, at their own discretion and risk. Anyone intending to use this information should first verify that the garment selected is suitable for the intended use. In many cases, seams and closures have shorter breakthrough times and higher permeation rates than the fabric. Please contact the garment manufacturer for specific data. If fabric becomes torn, abraded or punctured, end user should discontinue use of garment to avoid potential exposure to chemical.

3 Permeation uide for DuPont Tychem ThermoPro Protective Fabrics Effective January This guide replaces all previously published until superseded. How to Use this Permeation uide To Find Permeation Test Results 1. ocate the desired chemical in the Data Table or Index The Chemical Index is sorted by: Index by Chemical Abstract System (CAS) Number For each chemical, the following information is listed. Chemical name Chemical subclass number(s) CAS number Chemical name used in data table if name listed is a synonym Independent Testing All permeation tests are conducted for DuPont by independent testing laboratories. Except for the chemical warfare agents, all results are based on ASTM F739, "Test Method for Resistance of Protective Clothing Materials to Permeation by iquids or ases under Continuous Contact." Chemical warfare agents are tested using MI-STD282. All tests were conducted at room temperature unless otherwise noted. Copies of individual reports are available by calling What is Permeation? 2. ocate the name of chemical as listed in the data table 3. ocate the chemical in the data table. Permeation is a difficult concept to grasp because it can't be seen and does not require a hole in the barrier. It occurs when a chemical is absorbed until it saturates the barrier and then desorbs, or diffuses, from the opposite surface. You may have experienced permeation firsthand if you stepped in gasoline at a filling station. If you noticed the odor of gasoline in your car as you drove away you experienced two of the three steps involved in permeation absorption and desorption. The soles of your shoes absorbed some gasoline, then you smelled it as it desorbed from the bottom surface of your shoe. If you had stood in the gasoline long enough, the sole of your shoe would have become saturated with gasoline and the vapors would have started to desorb inside your shoe. When it comes to hazardous liquids, vapors or gases, permeation testing is required. DuPont is a trademark of E.I. du Pont de Nemours and Company.

4 Permeation uide for DuPont Tychem ThermoPro Protective Fabrics Effective January Replaces all previously published until superseded. How Permeation Tests Are Conducted Permeation tests are conducted following the ASTM F739 "Test Method for Resistance of Protective Clothing Materials to Permeation by iquids and ases." A swatch of test fabric is inserted into a special test cell, with the outside surface of the fabric toward the challenge chamber, thus exposing it to a challenge chemical. The inside surface of the fabric is toward the sampling chamber. If the chemical moves through the protective clothing fabric and is detected on the inside surface of the fabric, it is said to have permeated the fabric. ASTM F739 Test Cell Definitions of Terms for ASTM F739 Permeation rate: The rate at which the face of the fabric and the detection of permeation. Results of permeation tests are variable.the challenge chemical permeates the fabric. In An actual breakthrough time of does results reported here are averages of three or these tables, the permeation rate reflects the not mean there was no breakthrough. It means more separate tests. Users should not be steady state rate when chemical contact is that permeation was not detected. Permeation misled in assuming these breakthrough times continuous and all forces affecting permeation may have occurred, but at a rate less than the and permeation rates are exact. This variability have reached equilibrium. minimum detectable permeation rate (MDPR). should be taken into account in material selection. (See ASTM F739.)
