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.
To ensure correct use, read this Instruction Manual and the product’s Limited
Warranty and Terms of Sales prior to use of this product. The use of the product
implies that the Buyer and User agrees to Manufacturer’s Limited Warranty and
Terms of Sale. Keep this manual in a place where operators can access it easily
whenever necessary!
CAUTION!
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.

3. Clean the concrete surface of any foreign substances.
A foreign substance can be oor covering, adhesive residue, epoxy coating,
paint, curing and sealing compounds, waxes, dirt or oil stains, or any other
material residue on the slab surface. Remove concrete contaminants by shot
blasting, abrasive grinding wheel or diamond cup wheel. The use of wire brushes
or razor scraping may not be suitable for achieving a clean, open concrete slab
surface.
4. Prepare test area and schedule testing.
ASTM requires that a minimum of 20 x 20 inches of concrete surface area be
cleaned for each test (as described above) and allowed to remain open for at
least 24 hours before setting the calcium chloride test. Once the test is placed,
it must remain undisturbed for a period of 60 to 72 hours. Always plan carefully
in advance of testing to ensure open time after preparation and exposure time
during the testing period will allow for proper placement and retrieval.
QUANTITATIVE TEST METHOD FOR DETERMINING MOISTURE
VAPOR EMISSION RATE (ASTM F 1869)
►PURPOSE:
®
Moisture Test Kit is designed to quantitatively measure the rate of moisture
Alpha
vapor emission.
►CONTENTS:
Each test kit consists of one cylindrical container lled with anhydrous calcium
chloride and one transparent plastic dome with pre-installed sealant around the
perimeter.
gloves, cloth rags, utility knife, scale capable of measuring to nearest 0.1 gram
and duct tape.
►APPLICABLE STANDARDS:
A person using this test kit shall strictly follow the instructions given in the latest
ASTM F 1869 published by American Society for Testing & Materials. The copies

Page 5
of ASTM documents can be obtained from American Society for Testing and Ma-
terials. 100 Barr Harbor Drive, West Conshohocken, PA 19428. Tel: 610-832-9585
Fax: 610-832-9555. The documents may also be purchased on the internet from
www.astm.org.
►PREPARATION:
1. Survey Job Site Conditions - Verify environmental controls are operational.
The building temperature and humidity should be representative of what it
would be during normal use. The temperature should be between 65 to 85
degree and the relative humidity between 40% and 60% for a minimum of 48
hours prior to conducting tests.
2. Schedule Accordingly - The tests need to remain undisturbed for a minimum of
60 hours and a maximum 72 hours. On the rst day preparation will take place
and on the following day the tests will be set and retrieved in 60 to 72 hours.
3. Test Location & Frequency - Place tests throughout the area with some in the
middle of the building, at the perimeter, over cracks and joints and especially
in areas of potential moisture. The tests should be performed at a rate of three
tests for the rst 1,000 square feet and one test for each additional 1,000 sq feet.
You need to keep track of the following for your records:
1. Location of the tests
2. Test number
3. Ambient room temperature
4. Ambient humidity
5. Start date/End date
6. Start time/End time
7. Exposure time (15-minute increments)
8. Start weight/Ending weight
9. Weight gain
10. Note any unusual occurrences or damage to kit
11. Results of test
12. Flooring manufacturer’s moisture limits for materials to be installed.
13. Moisture testing can be done with relative accuracy; however, if one is to stray
from the test methods, your test could produce faulty results.

TEST INSTRUCTIONS
The following testing procedure is brief and is not meant to replace the most current
ASTM standards. Therefore, the User must get acquainted with the applicable
current ASTM standard and OSHA safety regulations prior to using this test kit.
STEP 1
Remove any foreign objects such as overspray, curing
compound and sealers from the concrete surface using
mechanical devices such as a grinder (photo shows
Alpha® Ecogrinder with dust carriage attached). Remove
dust from the concrete surface to insure proper adhesion
of the sealant. Strictly follow guidelines given by Occupational Safety & Health Administration (OSHA).
STEP 2
Weigh the container with the vinyl tape seal at the test location
immediately prior to initiating the
test (W1).
Note: Be sure the scale is set to grams, ounce scales will not work for this test.
Weigh to the nearest 0.1 gram and note this initial weight on the top of the container
label using felt tip pen or permanent marker as well as the time and date the test
was started (T1).
STEP 3
Remove the sealing tape from
the plastic container. Make sure
the tape does not get dirty or
lost since it will be needed to
reseal the container at the end
of the test.
Note: For best results, stick the tape on the outer wall of
the dome unit to keep it safe.

STEP 4
Peel off the paper protective backing from the black seal-
ant that is around the dome and discard. Make sure the
sealant material does not contact objects or clothing as it
is very sticky and intended to provide a secure, longlasting
seal to the concrete throughout the duration of the test.
STEP 5
Carefully remove the lid from the container that holds
the calcium chloride crystals. Do not spill the crystals.
It is easiest to turn it over and place it under the dish as
shown. It may also be secured to the top of the dome or
any other location as long as it is stored safely for reuse.
STEP 6
Install the test kit on the concrete oor. First, place the
open calcium chloride container on the concrete oor.
Make sure the crystals are relatively level. If any crystals
are spilled the test can be invalid.
STEP 7
Next, immediately place the dome unit over the center of the dish. Press rmly
along the edges of the sealant material to securely bond
the unit to the oor. To test for an airtight seal, press
rmly on the center of the cover. The cover should resist
pressure, if properly sealed.
Allow the test kit to remain undisturbed for a period of 60
to 72 hours. Note the ambient temperature and humidity
at the test area.

STEP 8
After 60 to 72 hours, remove the dome with a razor. Retrieve the dish with the
calcium chloride and immediately place the lid back on and reseal using saved
vinyl tape. Re-weigh the container on the same gram scale used at the start of
the test. Record weight, date and time (W2) (T2).
Note the weight as nal weight (W2). Do not spill any of the calcium chloride
crystals from the container. If any crystals are spilled, the test must be rerun with
a new test kit.

BIAS & PRECISION OF THE TEST
Follow guide lines provided by the latest ASTM. Our experience indicates that
the test results may vary with environmental and seasonal changes. The test
determines the rate of moisture vapor emission at the time of the test only. It does
not predict future moisture vapor emission rate or the performance of the ooring
material. The test performed at the same location at a different time may produce
different results.
