Scope
1.1 This test method covers the evaluation of the degree of flaking (scaling) of exterior paints by comparison with photographic standards.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 This test method is similar though not identical to ISO 4628 Part 5. ISO 4628 Part 5 uses a 0 to 5 rating scale, where a rating of 0 is no change and a rating of 5 is most severe. Test Method D772 uses a 10 to 0 rating scale, where a rating of 10 is no change and a rating of 0 is most severe. The two standards use different pictorial reference photographs for determining the rating values.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 Flaking failure of paint films can occur in use. This test method provides a means of evaluating the degree of failure by comparing to pictorial standards.
