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.

Effective June This guide replaces all previously published until superseded. Warning: fabrics should not be used around heat, flames, sparks, or potentially explosive environments. fabrics should have slip resistant or antislip materials on the outer surface of boots, shoe covers or other garment surfaces where slipping could occur.

4 Permeation Guide for DuPont Protective Fabrics Effective June This guide replaces all previously published until superseded. How to Use this Permeation Guide To Find Permeation Test Results 1. Locate the desired chemical in the Chemical Index. The Chemical Index is presented in two ways: Alphabetical Index Index by Chemical Abstract System () Number For each chemical, the following information is listed. Chemical name Chemical subclass number(s) number Chemical name used in data table if name listed is a synonym Whether the chemical has been tested (T) or not tested (nt) on Limited-Use and/or Reusable Fabrics 2. Locate the subclass(es) of the chemical in the permeation data table(s). There are two separate data tables, one for limited use fabrics, and one for reusable fabrics. 3. If the chemical has been tested, find the chemical name under its sub-class(es) and read across to find the permeation test results for the chemical. 4. If the chemical has not been tested, the subclass number is provided so users may view permeation data for tested chemicals in the same subclass. 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 Liquids or Gases under Continuous Contact". Chemical warfare agents are tested using MIL-STD282. All tests were conducted at room temperature unless otherwise noted. Copies of individual reports are available by calling What is Permeation? 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. Tyvek and are registered trademarks of E.

5 How Permeation Tests Are Conducted Permeation Guide for DuPont Fabrics. Effective June Replaces all previously published until superseded. Permeation tests are conducted following the ASTM F739 "Test Method for Resistance of Protective Clothing Materials to Permeation by Liquids and Gases." 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.) Minimum Detectable Permeation Rate Normalized breakthrough time: The time PLEASE NOTE: in Europe, normalized (MDPR): The minimum permeation rate that at which permeation rate reaches 0.1 µg/cm 2 /min. breakthrough times are based on a permeation can be detected during a permeation test. Normalized breakthrough times are used in rate of 1.0 µg/cm 2 /min. This is 10 times less MDPR is a function of the sensitivity of the this table.
