BSI 20/30401643 DC:2020 Edition

ISO 21716 provides a compilation and description of in vitro bioassay methods that can be useful for the toxicological screening of anti-fouling paints. Toxicological screening tests included in each part of ISO 21716 can be used for such purposes as early decision-making in research and product development, rapid feedback on potential toxicological concerns, or for the preliminary assessment of anti-fouling paints. ISO 21716 provides screening bioassays related to certain common genera of fouling organisms, namely barnacles, mussels and algae.

These screening tests are relatively simple and rapid laboratory tests that can be performed to provide an indication of toxicity of a painted surface towards selected test organisms. The screening tests described in each part of 21716 can be used as part of a tiered approach to predict the ability of an anti-fouling coating to prevent fouling on ships. Alternatively, to prevent the translocation of invasive marine species by progressively involving subsequent semi-field (e.g. raft panels) and field testing (e.g. ship trials). On their own, the screening tests described in each part of 21716 do not reliably predict the ability of an anti-fouling coating to prevent fouling on ships or prevent the translocation of invasive marine species. These screening tests should not be used in pesticidal or biocidal product registration schemes or for any other regulatory or administrative purpose.

This part of ISO 21716 describes general requirements for preparing and aging panels coated with anti-fouling paint when used in conjunction with other parts of ISO 21716 to perform laboratory bioassay screening tests against specified organisms. This part of ISO 21716 is applicable to all anti-fouling paints that prevent or deter the attachment and growth of sessile organisms on a surface through chemical or biological means.

This part of ISO 21716 is not applicable to the following:

• coatings that deter or prevent fouling solely by physical means such as biocide-free foul release paints;

• anti-fouling methods used for controlling harmful marine organisms and pathogenic organisms in ships’ ballast water and sediments according to the International Convention for the Control and Management of Ships’ Ballast Water and Sediments, 2004.
