    This specification covers glass fiber reinforced gypsum (GRG) composites suitable for producing GRG parts for non-loading bearings, thin sections, and ornamental shapes for architectural embellishment of interior building construction. Both the neat alpha gypsum cement and the resulting composite materials should conform to the specified physical and mechanical properties such as hardness, flexural strength, impact resistance, coefficient of linear thermal expansion, humidified deflection, surface burning characteristics, and nail pull resistance.

    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 glass fiber reinforced gypsum (GRG) composites having minimum properties and quality suitable to allow the production of GRG parts for non-loading bearing, thin section, ornamental shapes for architectural embellishment of interior building construction.

    1.2 The values stated in either inch-pound units or SI [metric] are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system shall be independent of the other. Values from the two systems shall not be combined.

    1.3 The text of this standard references footnotes which provide explanatory material. These footnotes shall not be considered as requirements of the standard.

    1.4 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.
