Standard Specification for the Installation of Molded Glass Fiber Reinforced Gypsum Parts

ABSTRACT
This specification covers the installation of molded glass fiber reinforced gypsum (GRG) parts. Molded glass fiber reinforced gypsum parts shall conform to environment conditions, substrate preparation, installation, and finishing requirements specified.
SCOPE
1.1 This specification covers the installation of molded glass fiber reinforced gypsum (GRG) parts.  
1.2 The values stated in either inch-pound units or SI (metric) are to be regarded separately as the standard. Within the text, SI units are shown in brackets. The values stated in each shall be used independent of the other. Values from the two systems shall not be combined.  
1.3 All references to finishes, dimensions and tolerances shall refer to the finished surface of the part.  
1.4 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
