ASTM C1230-96(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: C1230 − 96 (Reapproved 2023)
Standard Test Method for
Performing Tension Tests on Glass-Fiber Reinforced
Concrete (GFRC) Bonding Pads
This standard is issued under the fixed designation C1230; 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.
