Wallboard to Wood Framing
This standard is issued under the fixed designation D 6464; 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 (e) indicates an editorial change since the last revision or reapproval.
1. Scope 4. Significance and Use
1.1 This specification establishes minimum performance 4.1 This specification applies to expandable foam adhesives
requirements for determining strength, aging, and working used to bond the back surface of gypsum wallboard to
properties of expandable foam adhesives intended for bonding Douglas-fir dimensional lumber or other lumber species of
back surfaces of gypsum wallboards of all thicknesses to wood equivalent bonding qualities capable of meeting the test
framing. Minimum physical and performance requirements are requirements.
