ASTM C1278/C1278M-00

Standard Specification for Fiber-Reinforced Gypsum Panel

SCOPE
1.1 This specification covers fiber-reinforced gypsum panels described in 1.1.1-1.1.4.
1.1.1 Interior Fiber-Reinforced Gypsum Panels are designed to be used for walls, ceilings, or partitions and affords a suitable surface to receive decoration.
1.1.2 Water Resistant Fiber-Reinforced Gypsum Backing Panels are designed primarily to be used as a base for the application of ceramic or plastic tile on walls or ceilings. This product is also suitable for decoration.
1.1.3 Exterior Fiber-Reinforced Gypsum Soffit Panels are designed for use on exterior soffits and carport ceilings that are completely protected from contact with liquid water.
1.1.4 Water Resistant Exterior Fiber-Reinforced Gypsum Sheathing Panels are designed for use as sheathing on buildings.
1.2 Specifications applicable to all fiber-reinforced gypsum panels are located in Sections 1-4 and 9-11 except as modified by applicable product sections. Specifications applicable to specific panels are located in the following sections:Interior Fiber-Reinforced Gypsum Panels5Water-Resistant Fiber-Reinforced Gypsum Backing Panels6Exterior Fiber-Reinforced Gypsum Soffit Panels7Water-Resistant Exterior Fiber-Reinforced Gypsum Sheathing Panels8
1.3 The values stated in either inch-pound units or SI (metric) are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system shall be used independently of the other. Values from the two systems shall not be combined.
1.4 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes shall not be considered as requirements of the standard.
