ISO 13073-2:2013规定了一种风险评估方法，该方法旨在保护海洋环境免受防污系统的潜在负面影响，防污系统在船舶使用寿命期间故意使用杀菌活性物质。这种方法也可以在淡水环境中使用。 ISO 13073-2:2013未提供评估危害的具体试验方法，也未建议对某些防污系统的使用限制。它也没有提供使用特定物质的防污系统效能评估方法。

ISO 13073-2:2013 specifies a risk assessment method that protects the marine environment from the potential negative impacts of anti-fouling systems intentionally using biocidally active substances applied to a ship during its service life. This method can also be modified for use in freshwater environments. ISO 13073-2:2013 does not provide specific test methods for evaluating the hazards nor recommends usage restrictions for certain anti-fouling systems. It also does not provide an efficacy-evaluation method of the anti-fouling system using a specific substance.
