Observable moisture on the underside of the plastic sheet depends on astm d dew point, which in turn depends on the surface temperature of the concrete.

A positive result with observable moisture underneath the plastic sheet confirms that the concrete slab is too wet for a flooring installation.

And more importantly, expect flooring failures. The test method involves taping an inch mm square of polyethylene film onto a concrete slab and waiting at least 16 hours. If the document is revised or amended, you will be notified by email.

It can no longer evaporate through the surface.

x4263 Its approach has been scientifically proven to provide a true adtm of the overall moisture condition of the slab. The ASTM D Concrete Moisture Test A concrete floor slab with excess moisture pretty much guarantees a flooring failure due to serious problems such as discoloration, bubbles, curling, adhesive deterioration, cupping, buckling, warping, mildew or d42263.

Some methods of concrete moisture testing use a simple, qualitative approach. This standard is also available to be included in Standards Subscriptions. What happens next is that the moisture gradient will tend to disappear, bringing some moisture that was deeper down, up toward the surface.

Observable moisture on the underside of the plastic sheet depends on the dew point, which in turn depends on the surface temperature of the concrete.

Accurate Concrete Moisture Measurement? Your Alert Profile lists the documents that will be monitored. No serious flooring failures due to hidden, excessive moisture in the slab. However, the reverse is not true. And more importantly, expect flooring failures. Add to Alert PDF.

Any moisture condensation or observable darkening of the color of the concrete underneath the sheet x4263 excessive moisture and means the slab is not ready for a moisture-sensitive floor covering.

What happens next is that the astm d gradient will tend astm d disappear, bringing some moisture that was deeper down, up toward the surface.

Ultimately, this creates an appreciably wetter condition at astm d surface than either the Plastic Sheet D42263 or any other surface test will be likely to show.

The ASTM D Concrete Moisture Test

For specific caution statements, see Section 4. Already Subscribed to this document. Nor d it indicate whether additional moisture is entering the slab from below, such as in the absence of a vapor retarder. Need more than one copy? Instead, always rely on in situ RH moisture testing. As the voice of the U. A concrete floor slab with excess moisture pretty much guarantees a flooring failure due to serious problems such as discoloration, bubbles, curling, adhesive deterioration, cupping, buckling, warping, mildew or mold.

Yes, it matters a great deal.

So unless you take the moisture gradient into account and measure satm deeper within the slab, expect to be misled by your test results. Another plus is that the test provides hard numbers expressed as percent RH that make it very easy for deciding when the slab is dry enough for installing the finished floor. A positive result with c moisture underneath the plastic sheet confirms that the astm d slab is too wet for a flooring installation.

Ultimately, this creates an appreciably wetter condition at the surface than either the Plastic Sheet Test or any other surface test will be likely to show.
