Standard Test Method for Determining the Resistance of Paint Films and Related Coatings to Algal Defacement
ASTM D5589-25
Organization:
ASTM - ASTM International
Year: 2025
Abstract: 4.1 Defacement of paint and coating films by algal growth is a common phenomenon under certain conditions. It is generally known that differences in the environment, lighting, temperature, substrate, and other factors in addition to the coating composition affect the susceptibility of a given painted surface. This test method attempts to provide a means to comparatively evaluate different coating formulations for their relative performance under a given set of conditions. It does not imply that a coating that resists growth under these conditions will necessarily resist growth in the actual application. 4.2 Familiarity with microbiological techniques is required. This test method should not be used by persons without at least basic microbiological training.

| scope | 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 rankings from outdoor exposures. However, this test method should not be used as a replacement for exterior exposure since many other factors will affect those results. 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. | |
