The Moisture Vapor Emission Rate (MVER) is the equivalent weight of water (if
the gas turned into liquid) that emits from 1,000 square feet of concrete surface
area in 24 hours time.

1. Provide the number of test kits required.
Install 3 test kits for areas up to 1,000 sq. ft or smaller, add 1 test kit for each
additional 1,000 sq. ft. area thereafter.
2. Ensure interior environment is conditioned correctly before performing
tests.
a properly conditioned building interior has a temperature between 65 to 85
a properly conditioned building interior has a temperature between 65 to 85
degrees F. with a relative humidity of 40 to 60 % for at least 48 hours before
the test begins and remains consistent throughout the testing period of 60 to
72 hours. Record values on log sheet.
