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: D2095 - 96 (Reapproved 2023) INTERNATIONAL Standard Test Method for Tensile Strength of Adhesives by Means of Bar and Rod Specimens This standard is issued under the fixed designation D2095; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. Anumber in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval. 1.
