ASTM D7654/D7654M-10(2018)

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:D7654/D7654M −10 (Reapproved 2018)
Standard Specification for
Asphalt Used in Roofing Measured by Dynamic Shear
Rheometer
This standard is issued under the fixed designation D7654/D7654M; 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.
