The force required to pull the stud from the surface, together with the carrier, is measured. 1.1 These test methods cover procedures for determining the tensile strength of a section of portland cement-based plaster, the bond strength between portland cement-based plaster and a solid plaster base, or the fastener pull-out or lath pull-over strength for portland cement-based plaster bases over framing in either an exterior (stucco) or interior application. In case it is required, the plastering should be done in 2 coats. No correlation shall be made between laboratory and field testing. Gypsum. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard. These test methods cover the physical testing of gypsum panel products. For especially hard finish Abstract. Drill bit with centering point to obtain 20 mm dia. ). In fact a recent research on gypsum products reinforced with hemp and flax fibers showed that this addition could considerably delay the setting time of the pastes. These notes and footnotes, excluding those in tables and figures, shall not be considered as requirements of these test methods. 1.2 The test methods are suitable for use on portland cement-based plaster finish systems on both new and existing construction. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Gypsum plasters are perceived to have a number of advantages over lime, including easily controlled setting time according to function, less time delay between application of coats, they do not shrink on drying, and have excellent fire resistance. ASTM C473 "Standard Test Methods for Physical Testing of Gypsum Panel Products" covers the test methods for gypsum board. ). But if properly stored gypsum can be use in excessive of 6 … Partitions. 4.2 Because the test methods described in this standard are used for evaluation of portland cement-based plaster cured at least 28 days, load results obtained by either test method must be interpreted based on sound engineering practice, applicable building regulations, and codes having jurisdiction. Move the stud finder over the plaster wall across the spot where the heavy object will hang. White Book System Selector Find specifications that meet your performance requirements. Fastener Test Pull Out (Wood Stud): 525 lbs average. Gypsum Plaster. Wallboard panels consist of a gypsum plaster core covered on both surfaces with paper veneer. 6.2.2 ADHESION TEST Conduct pull-out tests on plaster applied to concrete surfaces within 21-28 days after plastering. Compressive Strength 12.3.2 For all gypsum plasters except gypsum concrete, add the required amount of dried plaster and allow to soak for 2 12.1 Significance and Use—This test method is used to min. Determination of an appropriate safety factor shall be left to the discretion of the test specifier.
