The ASTM D6132-1997 standard provides a non-Destructiveness measurement method for the measurement of dry-film thickness of organic coatings on concrete using an ultrasonic meter. This method is suitable for field structures, commercial products, or laboratory samples and provides accurate measurement of coating thickness on different substrates. It is not suitable for coatings that are easily deformed under measuring instrument load. The measurement range is 0.5 to 275 mils (10 microns to 7 mm). The standard emphasizes that coating performance is affected by Film thickness and notes safety and health responsibilities.
