ASTM F 1869 Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride
Lab ID: 114
MVER specification of most floor covering and adhesive companies is 3 to 5 lb/1000 sq ft/24 hr. Used to investigate acceptability of floors to receive floor coverings. Also used to evaluate distress due to moisture, mold/fungus growth.
Kits must be placed and collected by client or CTLGroup field staff, work which is not included in standard price. Consult CTLGroup contacts for detailed instructions.
Pounds of water vapor per 1000 sq ft per 24 hr.
