Standard Test Methods for Joint Treatment Materials for Gypsum Board Construction — 15 стр.
Реферат

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 testsfor viscosity, shrinkage, check cracking, and putrefaction; joint tape testsfor tensile strength, width, and thickness; paper joint tape testsfor dimensional stability; assemblages of paper joint tape and joint compoundfor bond of paper joint tape to joint compound and cracking of joint compound at tape edges; and glass-mesh joint tape testfor skewness.
