Standard Specification for Mineral Fiber Hydraulic-Setting Thermal Insulating and Finishing Cement
STANDARD published on 1.9.2026
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 mineral fiber (rock or slag) insulating and finishing cement shipped in dry-mix form, including hydraulic-setting binder, which, when mixed with water and applied in accordance with the manufacturer´s directions, affords a smooth surface as a final finish for heated surfaces for specific applications. The actual temperature limit shall be agreed upon between the purchaser and the manufacturer. Specimens shall be sampled, prepared, tested, and conform accordingly to the following properties: dry covering capacity, volume change upon drying, compressive strength, linear shrinkage, apparent thermal conductivity, maximum use temperature, and non-combustibility.
