Standard Specification for Contact Molded “Fiberglass” (Glass Fiber Reinforced Thermosetting Resin) Ducts
STANDARD published on 1.4.2021
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 the material and design requirements, and fabrication of ducts and hoods made of "fiberglass" (glass fiber reinforced thermosetting resin) consisting of a polyester, vinyl ester, or other qualified resin-matrix systems with fiber reinforcement manufactured by contact molding, intended for use in handling corrosive fumes and process gases. Special attention is given to equipment that operates at specified temperatures with regard to strength and corrosion resistance. This specification does not address the selection of resins and reinforcements for specific chemical environments.
