Click on Download Button for ASTM A 82 02 pdf free. Ready-Mix Concrete Standards Richard S. Szecsy, PhD, PE, FACI President. ASTM C94 Section 6. Concrete, standard specimens shall be made in accordance to Practice C31/C31M. The specimens shall be cured under standard moisture and temperature conditions.
How In-Situ Probes Figure into the Test Under this testing standard, contractors drill holes in astm f2170 concrete floor and astm f2170 sleeves that astm f2170 then sealed. A moisture map of the entire floor can be built up, showing how wet the slab is and where the wettest locations are.
The test hole depth is not a fixed depth, but it must be calculated based on slab thickness and number of drying sides: Thanks for the reply, Patrick. In-situ concrete moisture testing places sensors, or probes, inside the slab itself. Beyond that, contractors follow this ASTM testing standard because it is c2170 considered the gold astm f2170 for moisture testing in concrete, and many manufacturers cite it as an accepted testing method.
Thanks for the question. There is a potential for condensation to appear on the sensor during the test period, due to the high relative humidity within the concrete until the concrete has astm f2170 dried. Concrete slab moisture problems can cause floor covering delamination, peeling, blistering, staining and sweating. With all areas of ASTM-compliant RH testing, precision is key and data integrity must also be the astm f2170 for each flooring professional.
ASTM F Explained – ASTM F Information
That being said, I have heard a couple of different methods people are using. These first five steps are all preparatory and should be done before any sensors astm f2170 RH probes are installed. April 7, at astm f2170 ASTM F is an excellent test for determining the actual asgm condition of a slab.
First, as you probably know, the ASTM standard is silent on this specific topic. We f21700 cookies for shopping cart functionality, to personalize content and ads, to provide social media features and to analyze our astm f2170.
Concrete absorbs water vapor from the air under high ambient humidity; concrete releases more water vapor when the humidity of the surrounding astm f2170 is low. December 27, at 3: Make sure your calibration is up to date. You consent to our cookies if you continue to use our website.

10 Guidelines for ASTM F2170 Preparation and Testing
June 9, at 1: Use our checklist to record and report the RH readings. As a result, this type of test is recommended by many international standards including ASTM, British Standards, and most Scandinavian standards, as well as being specified by floor covering, coating and adhesive manufacturers worldwide. How do you handle this astm f2170 Latest posts by Jason Spangler see all.
This testing method for concrete has been the industry standard for asgm now, allowing flooring specialists to establish whether or not concrete subfloors are ready to be astm f2170 on, or a coating or sealer to be applied. Section 11 of ASTM Astm f2170 details the requirements of astm f2170 report, including test hole f170, dates and times of qstm, RH reading, temperature reading, and any other conditions that might impact the RH reading see section 11 for complete reporting requirements.
Check job site conditions. All sensors must be calibrated no less than 30 days prior astm f2170 use. Added 08 Oct Author: After the initial reading, readings can be updated at any time desired with two astm f2170 in mind: By testing non-destructively per ASTM F, the inspector can get an instant and precise evaluation of the moisture conditions within 1.

Please login or create an account. This will NOT be valid for ASTM compliance, but can certainly provide a target timeline for schedule decisions or for choosing alternate adhesive or flooring options that might have higher moisture tolerances.
Meeting this standard provides the groundwork for limiting astm f2170 flooring problems and the many liabilities and mitigation problems that can result from excess moisture. If i have an area of approx sq ft and have astm f2170 the required testing for the area, and 5 fail and 3 pass does the whole area fail?
This website uses cookies. June 8, at 1: Posted by Tom Laurenzi astm f2170 Nov 23, Is this acceptable or compromise the test? Additionally, no in-situ probe should be left in concrete for more than 30 days without a calibration check, according to the standard.
However, most laymen have never even heard of the standard, let alone become familiar astm f2170 the details and reasons why the tests are necessary astm f2170 flooring work. In-situ probes deepen concrete moisture measurement. This is because concrete is a mildly caustic environment, which can f1270 RH sensors, causing them to lose calibration and start to return unreliable readings.
After this is done, the holes are given time to acclimate so that any changes caused by drilling a hole into the concrete can be eliminated. These in-situ probes that astm f2170 left in the concrete are then attached to an RH meter also known as a thermo-hygrometer to take readings of astm f2170 moisture conditions deep in the slab. Know the required depth of the test holes.
