This new standard will assist specifiers, contractors and inspectors in determining the acceptability of a coating applied over concrete or masonry substrates. It establishes classification categories for the quantity of pinholes that appear in a defined area of applied coating and provides a procedure for defining the areas of applied coating that will be inspected. Evaluation of the coating is performed with the unaided eye at a distance of approximately 30 cm (12 inches) from the coated surface. The default Pinhole Frequency Level is Moderate (11 to 20 pinholes per ~1 square foot area) unless otherwise specified in the procurement documents. In this standard, no distinction is made between pinholes that expose an underlying coating layer and those that extend to the substrate, but the user is cautioned that procurement documents may have much more stringent acceptance criteria in some service environments.
