    This specification covers fiber-reinforced gypsum panel. The physical properties, dimensions and tolerances, and edges of interior fiber-reinforced gypsum panels, water-resistant fiber-reinforced gypsum backing panels, exterior fiber-reinforced gypsum soffit panels, water-resistant exterior fiber-reinforced gypsum sheathing panels, interior fiber-reinforced gypsum underlayment panels, and fiber-reinforced gypsum roof board panels are presented in details. The surfaces of the fiber-reinforced gypsum panels shall be true and free from imperfections that would render the panels unfit for use with or without decoration.

    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. 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.

    1.1.5 Interior Fiber-Reinforced Gypsum Underlayment Panels

    are designed for use as a base for application of finished flooring materials.

    1.1.6 Fiber-Reinforced Gypsum Board Panels

    are designed for use in roofing systems.

    1.2 Specifications applicable to all fiber-reinforced gypsum panels are located in Sections 1 – 4 and 11 – 13 except as modified by applicable product sections. Specifications applicable to specific panels are located in the following sections:

     Interior Fiber-Reinforced Gypsum Panels


     Water-Resistant Fiber-Reinforced Gypsum Backing Panels


     Exterior Fiber-Reinforced Gypsum Soffit Panels


     Water-Resistant Exterior Fiber-Reinforced Gypsum Sheathing


     Interior Fiber-Reinforced Gypsum Underlayment Panels


     Fiber-Reinforced Gypsum Roof Board Panels


    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.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
