Withdrawn Standard: ASTM D783 Tentative Method of Test for Water-Vapor Permeability of Paper and Paperboard (Withdrawn 1947)WITHDRAWN, REPLACED BY E96/E96M
其概述如下Significance and Use
The purpose of these tests is to obtain, by means of simple apparatus, reliable values of water vapor transfer through permeable and semipermeable materials, expressed in suitable units. These values are for use in design, manufacture, and marketing. A permeance value obtained under one set of test conditions may not indicate the value under a different set of conditions. For this reason, the test conditions should be selected that most closely approach the conditions of use. While any set of conditions may be used and those conditions reported, standard conditions that have been useful are shown in Appendix X1
