Significance and Use
4.1.1 Non metallic reinforced Portland Cement Based Plaster are vertically applied exterior wall claddings that may be subject to variety of conditions over the claddings service life. The series of tests described in this standard evaluates performance under a variety of test conditions and exposures. Any given project may not be subject to all of the test conditions described herein and all of the test methods may not evaluate all exposures for a given project.
4.4.1 Plaster bases serve as a key, reinforcement and attachment mechanism for Portland Cement Based Plaster. The thickness, profile, and material properties of the plaster bases must be such that it is adequately embedded in the Portland Cement Based Plaster. This can be accomplished through use of a self furred non metallic plaster base or other means such as furring strips. This test procedure determines the effectiveness of the furring mechanism to ensure that the minimum embedment is obtained.
