ASTM STANDARDS UPDATE !!!

With the recent changes to the ASTM 1884.2021 standards for Resilient Flooring, the ASTM F2420 (Hood Test) has been WITHDRAWN due to large variations between it & the in-situ probe test after 72 hours.


The ASTM F 1869 Anhydrous Calcium Chloride test is the secondary test to be used where holes cannot be drilled into the slab.

These calcium chloride moisture test kits are used to obtain a quantitative value that indicates the rate of moisture vapour emission from a concrete slab to determine if the slab is acceptable to receive the finished floor covering.

The kits also include pH test papers and distilled water used to measure the surface alkalinity of the concrete slab to determine if it meets the recommendations of the flooring or adhesive manufacturer. Inexpensive and easy to use, these kits are widely recommended by floorcovering product manufacturers and conform to the Australian ASTM 1884.2021 standards for testing of moisture.

Note: Please refer to Australian Standards for m2 requirement

Available in 1, 3 & 12 set kits.
