What is ISO 21716‑2 about?
ISO 21716-2 is an International Standard that discusses bioassay methods for screening anti-fouling paints.
ISO 21716‑2 is the second part in the multi-series of documents that focuses on bioassay methods for screening anti-fouling paints for barnacles.
ISO 21716‑2 specifies a laboratory test method for screening anti-fouling paints in a flow-through system using barnacle cyprid larvae as the test organism.
ISO 21716‑2 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.
Who is ISO 21716‑2 for?
ISO 21716‑2 on bioassay methods for screening anti-fouling paints for barnacles is applicable to:
- Ships and marine manufacturers
- Design engineers for anti-fouling paints
- Quality control personnel for anti-fouling paints
- Manufacturers of anti-fouling paints
- Laboratories involved in the inspection of anti-fouling paints
Why should you use ISO 217162?
Barnacles are typical marine sessile organisms regarded as harmful fouling organisms because of their impact on fuel consumption and the potential for translocation of non-indigenous species if they become attached to ship hulls.
ISO 217162 provides you with screening bioassays related to certain common genera of fouling organisms, namely barnacles. These screening tests are relatively simple and rapid laboratory tests that can be performed to provide you with an indication of the toxicity of a painted surface towards selected test organisms.
ISO 217162 gives you guidelines about screening tests and can be used as part of a tiered approach to predict the ability of anti-fouling paint to prevent fouling on ships.
You can test anti-fouling paints, following the guidelines provided in ISO 21716‑2, and evaluate the efficacy of anti-fouling paints. Evaluating the efficacy of these paints is vital to determine the fuel efficiency of the ship. Moreover, extremely toxic fouling-paints should be avoided since they pose as an environmental hazard.
