Significance and Use
4.2 The degree and type of fouling will vary depending on the environment. Differences in geographic location of test sites, time of year when panels are exposed, and weather conditions from one year to the next, can affect results. Such variables are accounted taking a fouling census on a nontoxic surface. For the exposure to be valid, the nontoxic surface should show heavy fouling accretion.
1.1 This practice covers a procedure to test a biofouling resistant coating systems or antifouling systems, or both, when subjected to in situ partial immersion exposure. This enhances settlement of certain marine fouling organisms and increase the rate of possible physical deterioration.
