This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. Designation: D7192 - 20 INTERNATIONAL Standard Test Method for High Speed Puncture Properties of Plastic Films Using Load and Displacement Sensors1 This standard is issued under the fixed designation D7192; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year oflast reapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval. 1.
