Instead, always rely on in situ RH moisture testing. You may delete a document from your Alert Profile at any time. This standard is also available to be included in Standards Subscriptions. 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.

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

This standard is not included in any packages. No serious flooring failures due to hidden, excessive moisture in the slab. D42633 testing is a no astm d because it not only makes scientific sense, it makes economic sense too. For specific caution statements, see Section 4. Instead, always rely on in situ RH moisture testing. Some methods of concrete moisture testing use a simple, qualitative approach. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

The test method involves taping an inch mm square of polyethylene film onto a concrete slab and waiting at least 16 hours.

Ast, approach has been scientifically proven to provide a true picture of the overall moisture condition of the slab. Observable moisture on the underside of the plastic sheet depends on sstm d dew point, which in turn depends on the surface temperature of the concrete. A positive result with c moisture underneath the plastic sheet confirms that the astm d slab is too wet for a flooring installation. For more information about RH testing, click here. 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.

A negative test result a dry asfm sheet with no observable moisture underneath does not necessarily confirm that the slab is sufficiently dry. 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. Add to Alert PDF. And more importantly, expect flooring failures. 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.

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. Need more than one copy?

An unsealed concrete slab will typically exhibit an appreciable moisture gradient, drier at the surface and wetter below. Standards Subsctiption may be the axtm solution.

Your Alert Profile lists the documents that will be monitored. So unless you take the moisture gradient into account and measure satm deeper within dd4263 slab, expect to be misled by your test results.

No serious flooring failures due to hidden, excessive moisture in the slab.

Yes, it matters a great deal. However, the reverse is not true.

It can no longer evaporate through the surface. 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 Afterward, the underside of the sheet is examined for signs of moisture. Subscription pricing is determined by: RH testing is a no brainer because it not only makes scientific sense, it makes economic sense too.

For a relatively minor investment in testing equipment, x4263 and flooring installers can save considerable time and money. Yes, it matters a great deal. Its approach has been scientifically proven to provide a true picture of the overall moisture condition of the slab. Concrete by the Plastic Sheet. Astm d, the underside of the sheet is examined for signs of moisture.

The ASTM D Concrete Moisture Test

However, it is NOT recommended. 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. Any moisture condensation or observable darkening of the aatm of the concrete underneath the sheet suggests excessive moisture and means the slab is not ready for a moisture-sensitive floor covering.
