BS ISO 21716-2:2020

This standard BS ISO 21716-2:2020 Ships and marine technology. Bioassay methods for screening anti-fouling paints is classified in these ICS categories:

• 13.020.99 Other standards related to environmental protection
• 47.020.99 Other standards related to shipbuilding and marine structures

This document specifies a laboratory test method for screening anti-fouling paints in a flow-through system using barnacle cyprid larvae as the test organism. It is intended to be used in conjunction with ISO 21716-1, which specifies the general requirements. 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. Examples of statistical analysis to determine if the difference in barnacle settlement is statistically significant are given in Annex A.
