The formula for calculation of test results is as follows: MVER = 24,000 X Gain / 453.612 X Area X Time. MVER = Moisture Vapor Emission Rate Gain = Weight gain of calcium chloride crystals in grams *Area = Area of dome contact to slab, less area of dish contact in square feet. Time = Exposure time in hours.
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.
The calcium chloride test, sometimes called the moisture vapor emission rate (MVER) test, is simple inexpensive and widely accepted. It takes advantage of the fact that calcium chloride absorbs moisture like a sponge.
Testing: 1. Expose a minimum area of 20 by 20 in. (50.8 by 50.8 cm) to conditions specified above for a minimum period of 24 hrs. prior to starting each test. Weigh the container of calcium chloride, including the container lid and the label which should be affixed to the lid.
Calcium Chloride Moisture Test Procedure. 1. plan your test carefully. Before you test, make sure you have basic tools for cleaning the slab including a scraper and wire brush. Make sure you have a quality gram scale and a proper supply of test kits.
