When To Test Concrete To ASTM F2170?

Be sure to familiarize yourself with ASTM F and choose the best concrete moisture asgm method for the job. Without it, even a well-dried and functioning foundation can end up with concrete slab moisture problems.

September 6, at However, most laymen astm f2170 never even heard of the standard, let alone become familiar with astm f2170 details and reasons why the tests are necessary for flooring work. The standard provides precise guidelines for Astm f2170 testing methods.

Concrete slab moisture problems can cause floor covering delamination, peeling, blistering, staining and sweating.

Additionally, no in-situ probe should be left in concrete for more than 30 days without a calibration check, according to the standard. All sensors must be calibrated no less than 30 days prior to use. astm f2170

The readings will remain high until the sensor is allowed to dry in fresh air. In that case, builders did not allow the slab sufficient time for concrete moisture levels to equilibrate reach equilibrium moisture content according to relative humidity RH. By testing non-destructively per ASTM F, the inspector can get an instant and precise evaluation of the moisture conditions within 1.

Preparation Confirm your test method equipment meets specifications. Subscribe to Email Updates. This is because concrete is a mildly caustic environment, which can damage RH sensors, causing them to lose calibration and start to return unreliable readings. Thanks astm f2170 the question. Events Astm f2170 Technical Articles. Check job site conditions. Each test hole must be drilled to astm f2170 depth determined at Step 5 above section 10 of ASTM Astm f2170 and properly prepared.

This can only be done with reusable relative humidity probes that can be removed after one hour and reinserted at any time in the future to ensure accurate results. This moisture map helps the user determine where astm f2170 is best to locate the sensors for F These first five steps are all preparatory and should be done before any sensors or RH probes are installed. Know the required depth of the test holes. Beyond that, contractors follow this ASTM testing standard because it is often considered the gold standard for moisture testing in concrete, and many manufacturers cite it as an accepted testing method.

ASTM F formally recognizes the use of astm f2170 situ probes as a means of conducting relative humidity testing. I would verify that the hole depths are consistent and that environmental conditions are at service conditions.

We recommend placing astm f2170 serial number astm f2170 which also helps track certification of each sensor on the corresponding test hole on the mapped report.

What is ASTM-F, and How do Concrete RH Sensors Figure into it?

Note astm f2170 the liner requirements have been updated and the hole is astm f2170 be fully lined to meet the ASTM standard. How In-Situ Probes Ast, astm f2170 the Test Under this testing standard, contractors drill holes in a concrete floor and insert sleeves that are then sealed. While a pin or even pinless moisture meter can give a general idea of the presence of moisture, their results do not provide information upon which to make sound decisions.

Some inexperienced individuals try to asfm a pin moisture meter for concrete floor testing rather than following the rigorous ASTM standard.

If astm f2170 have an area of approx sq ft and astm f2170 done the required testing for the astm f2170, and 5 fail and 3 pass does the whole area fail? Save my name, email, and website in this browser for the next time I comment.

Section 11 of ASTM F details the requirements of each report, including test hole location, dates and times of measurements, RH reading, temperature reading, and any other conditions that might impact the RH reading see section 11 for complete reporting requirements.

The only thing we recommend is that you ensure that there is a good seal between the sensor body and the concrete wall. If you forward to 1: December 27, at 3: June 9, at 1: And moisture can still be an issue at grade so concrete foundations astm f2170 be designed to include proper moisture drainage.
