The ASTM D772-18 standard provides a method for assessing the degree of exterior coating flaking by comparison with the photographic standard. The method uses a scale of 10 to 0 to describe the severity of Coating flaking, where a level of 10 indicates no flaking and a level of 0 indicates the most severe flaking. The standard is similar to ISO 4628 Part 5, but employs a different scale of grades and pictorial references to more accurately reflect Coating flaking. The standard helps users provide a reliable reference in evaluating Coating performance and maintenance.
