Standard Test Method for Determining the Resistance of Paint Films and Related Coatings to Algal Defacement

Importancia y uso:

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.
