Standard Test Method for Determining the Resistance of Paint Films and Related Coatings to Algal Defacement
1.1 This test method covers an accelerated method for determining the relative resistance of a paint or coating film to algal growth.
Note 1: It is hoped that a ranking of relative performance would be similar to that ranked from outdoor exposures. However, this test method should not be used as a replacement for exterior exposure since many other factors, only a few of which are listed will affect those results.
Note 2: ASTM weathering standards are no longer referenced in this document, but Practices D822, D4141, D4587, D5031, and D6695 are commonly used.
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 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.
1.4 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.
