ASTM E2098/E2098M-13(2023)

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: E2098/E2098M − 13 (Reapproved 2023)
Standard Test Method for
Determining Tensile Breaking Strength of Glass Fiber
Reinforcing Mesh for Use in Class PB Exterior Insulation
and Finish Systems (EIFS), after Exposure to a Sodium
Hydroxide Solution
This standard is issued under the fixed designation E2098/E2098M; 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 of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
