Calcium Chloride Test

Calcium Chloride Test

Calcium Chloride (CaCl) (ASTM F-1865) tests measure the moisture drive at the surface in values of pounds per 1,000 Sq. Ft. over a 24 hour period. Typical moisture limits are:

  • 3lbs for sheet goods, carpet tile and some epoxy flooring systems
  • 5lbs for VCT
CaCl testing needs to be conducted in normal building service conditions. Vapor drive values are highly sensitive to ambient condition and often provide false results when conducted in un-conditioned spaces.
