Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.INTRODUCTIONPromulgation of standard test methods for measuring the resistance of prote

3、ctive clothing materialsto permeation by liquid or gaseous chemicals has fostered the generation of increasing volumes ofmaterial performance data. Not all data have been nor will be generated using Test Method F 739.To be useful, such data should be combined with information that specifies detailed

4、 characteristicsof each test. These characteristics include information on the material specimens, challenge chemicals,test apparatus, analytical method used and test conditions (for example, temperature). The sensitivityor detection limit of the test system is of particular importance in comparing

5、the data from differentsources during the protective clothing selection process.To date, most reports on permeation testing have not included such specificity. This guide, therefore,presents a standard format for recording all required information and data. The standard format isintended to facilita

6、te the use of electronic databases to store, retrieve and apply test results.1. Scope1.1 This guide provides a format for documenting informa-tion and performance data from a permeation test.1.2 Documented information and data are grouped into fivemajor categories that define important aspects of ea
