Standard Specification for Glass Fiber Reinforced Gypsum Composites
STANDARD published on 1.4.2025
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

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.
