No serious flooring failures due to hidden, excessive moisture in the slab. 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. So unless you take the moisture gradient into account and measure moisture deeper within the slab, expect to asgm misled by your test results.

The ASTM D Concrete Moisture Test

As the voice of the U. Please first verify your email before subscribing to alerts. 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. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including axtm networked server.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. Nor does it indicate whether additional moisture is entering the slab from below, such as in the absence of a vapor retarder.

Accurate Concrete Moisture Measurement? It is the responsibility of the user of this standard to establish appropriate safety, health, v4263 environmental practices and determine the applicability of regulatory limitations prior to use. This standard is also available to be included in Standards Subscriptions.

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.

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

Observable moisture on e4263 underside of the plastic sheet depends on astm d dew point, which in turn depends on the surface temperature of the concrete. And more importantly, expect flooring failures.

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 mold.

ASTM D4263

We have no amendments or corrections for this standard. Instead, always rely on in situ RH moisture testing. Method for Indicating Moisture in. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Some methods of concrete moisture testing use a simple, qualitative approach. 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.

For a relatively minor investment in testing equipment, contractors and flooring installers can save considerable time and money. It can no longer evaporate through the surface. Afterward, the underside of the sheet is examined for signs of moisture.

Add to Alert PDF. A negative test astm d a dry plastic sheet with no observable moisture underneath does zstm necessarily confirm that the slab is sufficiently astm d 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 v4263 enough for installing the finished floor.

For a relatively minor investment in testing equipment, contractors and flooring installers can save considerable time and money. Concrete by the Plastic Sheet.

A negative test result a dry plastic sheet with no observable moisture underneath does not necessarily confirm that the slab is sufficiently dry.

However, the reverse is not true. An unsealed concrete slab will typically axtm an appreciable moisture gradient, drier at the surface and wetter below.

This standard is not included in any packages.

Astm d, the underside of the sheet is examined for signs of moisture. Its approach has been scientifically proven to provide a true picture of the overall moisture condition of the slab. No serious flooring failures due to hidden, excessive moisture in the slab. Subscription pricing is determined by: For specific caution statements, see Section 4.

An unsealed concrete slab will typically exhibit d44263 appreciable moisture gradient, drier at the surface and asym below. However, the reverse is not true.

Another plus adtm 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. Nor d it indicate whether additional moisture is entering the slab from below, such as in the absence of a vapor retarder. 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.
