Kahulugan at paggamit

4.1 Sa ilalim ng ilang mga kondisyon, algal growth of paint and film contamination is a common phenomenon. It is well known that differences in environment, light, temperatura, substrate, and other factors in addition to paint compositions can affect the susceptibility of a given painted surface. This test method attempts to provide a way to compare and evaluate the relative properties of different coating formulations under given conditions. This does not mean that a coating that resists growth under these conditions will necessarily resist growth in real-world applications (tingnan sa tala 1).

4.2 Familiarity with microbial technology is required. People without at least basic microbiological training should not use this test method.

ASTM D5589-2009 “Standard Test Method for Determining Resistance of Paint Film and Related Coatings to Algal Fouling”

Hakbang 1: Saklaw

1.1 The test method includes an accelerated method for determining the relative resistance of paint or coating to algal growth.

Tala 1 – The rankings for relative performance of hope are similar to those for outdoor exposure. Gayunpaman, this test method should not be used as a substitute for external exposure because many other factors, only some of which are listed, can affect these results.

1.2 Values expressed in SI units shall be considered standard. Ang mga halaga na ibinigay sa mga panaklong ay para sa sanggunian lamang.
