14 Σεπ 2023 · The calcium chloride moisture test has been the industry standard for making this determination and is a practical, well-established and accepted test of dynamic moisture. It will produce quantified results directly applicable to flooring manufacturer's specifications.
The CaCl moisture test is a building practice with lineage. It remains rooted in ASTM standard F1869 as the source of many tests tried. But their truth has entered a new era and the challenges of moisture emissions-based testing are becoming increasingly clear.
14 Ιουλ 2023 · The ASTM F1869 standard provides the guidelines for conducting the calcium chloride moisture test, used in measuring the moisture vapor emission rate (MVER) for concrete subfloors. This test can be done using the calcium chloride moisture test kit which is readily available for about $20.
11 Απρ 2023 · As continued testing confirmed its inadequacies, the ASTM F1869 standard for using CaCl was changed in 2010 to specifically disallow CaCl testing for all lightweight aggregate concrete. This article discusses the evolution of concrete moisture testing and why in situ RH testing, according to ASTM F2170 , has for a number of years now been ...
23 Σεπ 2024 · ASTM International has provided several standards related to testing moisture conditions with two different test methods before installing flooring over a concrete slab: in-situ probes (ASTM F2170) and calcium chloride testing (ASTM F1869).
1.1 These test methods cover the analysis of calcium chlo-ride and solutions. 1.2 Procedures are given for the determination of calcium chloride, magnesium chloride, potassium chloride, sodium chloride, and calcium hydroxide. The test methods appear in the following order: Sections Calcium Chloride 8 to 16 Magnesium Chloride, Potassium Chloride,
Standard Test Method for Measuring Moisture Vapor Emission Rate of Concrete Subfloor Using Anhydrous Calcium Chloride1 This standard is issued under the fixed designation F1869; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
