1.3Â The values stated in inch-pound units are to be regarded as standard. The values given in brackets are mathematical conversions to SI units that are provided for information only and are not considered standard.
These test methods cover the physical testing of joint treatment materials such as joint compound, paper joint tape, glass-mesh joint tape, and an assembly of joint compound and paper joint tape. These materials are used in gypsum board construction. The test methods are detailed for the following: joint compound tests—for viscosity, shrinkage, check cracking, and putrefaction; joint tape tests—for tensile strength, width, and thickness; paper joint tape tests—for dimensional stability; assemblages of paper joint tape and joint compound—for bond of paper joint tape to joint compound and cracking of joint compound at tape edges; and glass-mesh joint tape test—for skewness.
