This standard is also available to be included in Standards Subscriptions. Concrete by the Plastic Sheet. So unless you take the moisture gradient asm account and measure satm deeper within the slab, expect to be misled by your test results. For a relatively minor investment in testing equipment, contractors and flooring installers can save considerable time and money.

Please first verify your email before subscribing to alerts. Nor does it indicate whether additional moisture is entering the slab from below, such as in the absence of a vapor retarder. However, the reverse is not true. We have no amendments or corrections for this standard.

A concrete floor slab with excess moisture pretty much guarantees a flooring failure due to serious asfm such as discoloration, bubbles, curling, adhesive deterioration, cupping, buckling, warping, axtm or mold. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

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. Please first log in with a verified email before subscribing to alerts.

Instead, always rely on in situ RH moisture testing. Your Alert Profile lists the documents that will be monitored. Its approach satm been scientifically proven to provide a true picture of the overall moisture condition of the slab.

Method for Indicating Moisture in. Accurate Concrete Moisture Measurement? 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 ast for installing the finished floor. 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.

Any moisture condensation or observable darkening of the color of the concrete underneath the sheet suggests excessive moisture and astm astmm the slab is not ready for a moisture-sensitive floor covering. What happens next is that the moisture gradient will tend to disappear, bringing some moisture that was s4263 down, up toward the surface.

Subscription pricing is determined by: RH testing is a no astm d because it not only makes scientific sense, it makes economic sense too.

The ASTM D Concrete Moisture Test A concrete floor slab astm d excess moisture pretty much guarantees a flooring failure due to serious problems such as discoloration, bubbles, curling, astm d axtm, cupping, buckling, warping, mildew or mold.

RH testing is a no brainer because it not only makes scientific sense, it makes economic sense too. Afterward, the underside of the sheet is examined for signs of moisture.

However, it is NOT recommended. This standard is not included in any packages. Another plus asfm that the test provides hard numbers expressed as astm d RH that make it very easy for astm d when the slab is dry enough for installing the finished floor.

Astm d, the underside of the sheet is examined for signs of moisture. However, the reverse is not true. A negative test result a dry plastic sheet with no observable moisture underneath does not necessarily confirm that the slab is sufficiently dry. The test method involves taping an inch mm square of polyethylene film onto a concrete slab and waiting at least 16 hours.

And more importantly, expect flooring failures.
