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.

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 contain rapid laboratory tests that can be performed to provide an indication of the toxicity of a paint surface towards selected test organisms. The screening tests described can be used as part of a tiered approach to predict the ability of an anti-fouling coating to prevent fouling on ships or 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 these documents do not reliably predict the ability of an anti-fouling coating to prevent fouling on ships or 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 a laboratory test method for screening anti-fouling paints in a flow-through system using barnacle cyprid larvae as the test organism. Cyprids of barnacle species Amphibalanus amphitrite are recommended. Other barnacle species may be used if Amphibalanus amphitrite is not available. The purpose of the test is to determine if there is a difference in barnacle settlement on painted test panels compared with barnacle settlement on inert non-toxic control panels under the conditions of the test. Statistical treatments may be applied to determine if the difference in barnacle settlement is statistically significant.

This part of ISO 21716 describes a laboratory test method for screening anti-fouling paints in a flow-through system using mussels as the test organism. Young mussels, Mytilus galloprovincialis, are recommended. Other mussel species may be used if Mytilus galloprovincialis is not available. The purpose of the test is to determine if there is a difference in mussel settlement on painted test panels compared with mussel settlement on inert non-toxic control panels under the conditions of the test. Statistical treatments may be applied to determine if the difference in barnacle settlement is statistically significant.

This document specifies the requirements for determining the maximum propulsion power rating using manoeuvring speed for engine-driven craft with a length of the hull (LH, as defined in ISO 8666) between 8 m and 24 m. This document is applicable to craft with a calculated Froude number (Fn) ≥ 1,1. This document is not applicable to: — inflatable craft, as defined by ISO 6185‑4; — craft designed and constructed solely for competitive racing (racing craft); — craft primarily designed not to be engine driven. This document does not specify craft constructional strength requirements related to maximum propulsion power rating and does not guarantee stability under all conditions of seaway, wind, wakes and waves.

This document specifies the methodology to conduct computational modelling of ultraviolet (UV) reactor designs for ballast water management systems that incorporate ultraviolet disinfection technology (UV BWMS). The computational modelling shall be used to calculate UV Reduction Equivalent Dose (RED) and compare calculated REDs of the scaled model to its base model. It should be noted that the IMO requires validation of the computational model. Also, to be noted is that a complete UV BWMS typically incorporates other treatment methodologies such as filters, and the impact of changes to external subsystem performance on the overall BWMS is not considered in this document.
