Significance and Use
This test method is designed as a screening test to evaluate the performance of applied coating systems and other materials designed to resist biofouling settlement.
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.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
