INTRODUCTION
Thank you for purchasing the Alpha
®
Moisture Test Kit, a calcium chloride test for
determining if the concrete slab is suitable for oor covering or polymer coating
installations.
The test works by absorbing moisture in a vapor form that is exiting the slab’s
surface due to natural environmental factors over a period of time.
The test measures an approximate 70 square inches area of concrete surface for
60 to 72 hours, then a simple calculation is followed that determines the volume
of the vapor emission.
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.

ASTM F 1869 PROTOCOL CHECKLIST FOR CONDUCTING
THE CALCIUM CHLORIDE TEST
Before starting the test, make sure the following conditions are met:
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
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.
