Rationale

This test method has applications in the roofing and flooring industry as it relates to the installation of roofing and flooring products. At this time a number of manufacturers of roofing materials requires the architect or engineer to decide when it is acceptable to install roofing products over a concrete deck. However, there are no reliable means to assess the moisture content of the concrete in the field, especially for roof decks. The intent of this test method is to determine the minimum duration of time needed for the release of the free moisture in the concrete. This duration could then be used by a design professional as the minimum time needed before a material could be installed. As more data from testing is compiled, it may be possible to extrapolate the data to actual conditions in the field.
