Historical (view previous versions of standard)
This specification covers the minimum requirements for gypsum veneer plaster and includes application methods on systems such as electric heat cable systems but not exceeding a specified temperature. Applicable building code regulations should be followed when a specific degree of fire resistance is required. Plaster and other cementitious materials should be kept dry until these are ready to be used and should be kept off the ground, under cover, and away from damp walls and surfaces.
This abstract is a brief summary of the referenced standard. 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. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers the minimum requirements for and methods of applying gypsum veneer plaster.
1.2 Where a specific degree of fire resistance is required for veneer plaster systems, applicable building code regulations shall be followed.
1.2.1 Details of construction for a specific assembly to achieve the required fire resistance shall be obtained from reports of fire-resistance tests, engineering evaluations, or listings from recognized fire testing laboratories.
1.3 Where a specific degree of sound control is required for veneer plaster assemblies and constructions, details of construction shall be in compliance with official reports of tests conducted in recognized sound testing laboratories in accordance with the applicable sound tests of Test Methods E90, C423, or E492.
Note 1—To ensure desirable results, coordinate this specification with Specification C844.
Note 2—General information regarding matters of a contractual nature concerning veneer plaster work is found in Appendix X1. Additional technical information related to veneer plastering is provided in Appendix X2.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.
