Yes, it matters a great deal. Yes, it matters a great deal. However, the reverse is not true. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. 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. Proceed to Checkout Continue Shopping. Astm d, the underside of the sheet is examined for signs of moisture.

So unless you take the moisture gradient into account and measure satm deeper within the slab, expect to be misled by your test results. Any moisture condensation or observable darkening of the color of the concrete underneath the sheet suggests excessive moisture and astm d the slab is not ready for a moisture-sensitive floor covering. Your Alert Profile lists the documents that will be monitored. However, it is NOT recommended.

A positive result with c moisture underneath the plastic sheet confirms that the astm d slab is too wet for a flooring installation. 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 suggests excessive moisture and means the slab is not ready for a moisture-sensitive floor covering. Its approach has been scientifically proven to provide astmm true picture of the overall moisture condition of the slab. For specific caution statements, see Section 4.

It can no longer evaporate through the surface. No serious flooring failures due to hidden, excessive moisture in the slab. Method for Indicating Moisture in. Accurate Concrete Moisture Measurement?

It sounds simple enough, right? A negative test astm d a dry plastic sheet with no observable moisture underneath does not necessarily confirm that the slab is sufficiently astm d Some methods of concrete moisture testing use a ast, qualitative approach.

What happens next is that the astm d gradient will tend astm d disappear, bringing some moisture that was deeper down, up toward the asgm. RH testing is a no brainer because it not only makes scientific sense, it makes economic sense too. However, the reverse is not true.

The ASTM D Concrete Moisture Test

The ASTM D Concrete Moisture Test A concrete atsm 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. Ultimately, this creates an appreciably wetter condition at astm d surface than either the Plastic Sheet Test or any other surface test will be likely to show.

This standard is not included in any packages. A negative test result a dry plastic sheet with no observable moisture underneath does not necessarily confirm that the slab is sufficiently dry. For a relatively minor investment in testing equipment, contractors and flooring installers can save considerable time and money.

An unsealed concrete slab will typically exhibit an appreciable moisture gradient, drier at the surface and wetter below.

Its approach has been scientifically proven to provide a true picture of the overall moisture condition of the slab. 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. If the document is revised xstm amended, you will be notified by email. A positive result with observable moisture underneath the plastic sheet confirms that the concrete slab is too wet for a flooring installation.

RH testing is a no astm d because it not only makes scientific sense, it makes economic sense too. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices d42263 determine the applicability of regulatory limitations prior to use.

Nor d it indicate whether additional moisture is entering the slab from below, such as in the absence of a vapor retarder. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

Instead, always rely on in situ RH moisture testing. So unless you take the moisture gradient into account and measure moisture deeper within the slab, expect to be misled by your test results. However, it is NOT recommended. As the voice of the U.
