TOWACO, N.J. – (December 20, 2013) – Accuracy is your protection today when it comes to testing Relative Humidity (%RH) in concrete. The fact of the matter is that over the last decade a technician’s analysis of moisture in concrete floors and slabs has become far more important in today’s litigious society, and following a standard like ASTM F2170 is important. An error can result in issues later; therefore knowledge of testing procedures, precision of the testing equipment and proof that the site being tested was properly installed are essential.
“Today we live in a litigious world and the issue of accuracy is crucial,” said Paul Laurenzi, vice president of Sales & Marketing for Delmhorst Instrument Co. “Regulations guide the technician and knowledge of and abiding by the rules ensures a successful and satisfactory job, which in the long run will keep one’s reputation of excellent workmanship in good standing. For technicians working with concrete keeping up with the regulations is essential and precise RH testing is a must.”
Here are ten tips to accurate concrete RH readings to comply with ASTM F2170-11 Standards:
1. When installing testing sleeves, you must first drill to the proper depth. Follow standard such as ASTM F 2170 other guidelines suitable for your particular application.
2. After drilling a hole, vacuum it out and inspect it so there is no excess dust or metal particle contaminants from reinforcement products. Contaminants and/or dust interfere with sensor performance. Vacuuming is required under ASTM F2170 guidelines.
3. Use the right sleeve for the location. Flush sleeves are less prone to damage or interference at an active worksite.
4. Ensure the sleeve has a tight fit so that humidity does not escape from the hole. The sleeve should be snug at the sides. Sealing the tubes flange at the top of the sleeve with silicon as it’s being inserted into the cleaned drill hole is recommended. (Sealing is required under ASTM F2170)
5. Use clean caps on the sleeve and make sure they have a snug fit so that humidity cannot escape and air cannot infiltrate.
6. When a probe type sensor is being inserted in RH measuring sleeve in indoor applications, check the condition of the sensor that’s providing the RH reading to make sure it’s not being contaminated by moisture off gassing.
7. Regularly check your device and sensor for contaminants, abrasion, or anything that may affect your readings.
8. Always follow the maintenance and calibration protocols for the RH meter you’re using.
9. Always check with the device manufacturer’s tech support if you have any questions about your readings or equipment.
10. Photograph and record the dates, times and testing conditions, then “file” them with the project records.
According to Laurenzi every situation is unique for RH readings in concrete flooring and slabs. Some readings and controls have to be more exact than others, but accuracy is always important.
