　　英文名称：Standard Specification for Application of Gypsum Base to Receive Gypsum Veneer Plaster

　　原文名称：Standard Specification for Application of Gypsum Base to Receive Gypsum Veneer Plaster

　　范围：This specification covers the minimum requirements for, and methods of, application of gypsum veneer base for gypsum veneer plasters. 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. The materials shall be classified as follows: gypsum base for veneer plasters; gypsum backing board for coreboard; special fire-retardant gypsum base; foil-backed gypsum base; gypsum veneer plaster; nails; non-load bearing steel; load bearing steel; steel framing, non-load bearing; accessories; adhesives; steel framing load bearing; and wood framing. The maximum spacing of framing members for singly gypsum base construction shall be not more than then specified values. Application of gypsum base, single-ply gypsum base, adhesive-mechanical fastener, foil-backed gypsum base, two-ply gypsum base, and application over existing surfaces shall be indicated. Solid gypsum base partitions shall include face ply, core, and runners. Direct adhesive application shall be used only on interior masonry or concrete walls above grade, or inside of exterior masonry cavity walls.
