1.1 本试验方法包括通过侵蚀或烧蚀测定海洋防污（AF）涂层的防污性能和减少厚度（见第节） 3. )在海水中流体动剪应力与海水中静态暴露交替的特定条件下。包括具有已知性能的防污涂层系统，作为防污研究中的对照。 1.2 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关具体的危险声明，请参阅第节 8. . 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 有效的防污涂料对于保持船舶速度和降低运营成本至关重要。本试验方法设计为一种筛选试验，用于在水流引起的流体动应力条件下评估防污涂层系统，同时静态暴露在污垢环境中。动态测试是必要的，因为AF涂层的可用性越来越高，其设计用于在使用中烧蚀以暴露新的防污表面。由于没有船舶持续航行，因此包括静态暴露阶段，以使污垢微生物有机会在静态条件下附着。 在最初的30天静态暴露后，建议将交替的30天动态和静态暴露作为一个标准周期。选择初始静态暴露来表示在工作完成时从干船坞出来并坐在pierside的船舶。这使油漆有时间失去任何残留溶剂、完全固化、吸收水分，并且通常稳定在水环境中。 5.2 本试验方法旨在与在保护船体水下部分方面具有已知性能的控制防污涂层进行比较。本试验方法给出了海船用防污涂料的性能和预期使用寿命。然而，该测试方法与服务性能之间的相关性程度尚未确定。

1.1 This test method covers the determination of antifouling performance and reduction of thickness of marine antifouling (AF) coatings by erosion or ablation (see Section 3 ) under specified conditions of hydrodynamic shear stress in seawater alternated with static exposure in seawater. An antifouling coating system of known performance is included to serve as a control in antifouling studies. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For a specific hazards statement, see Section 8 . 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 Effective antifouling coatings are essential for the retention of speed and reduction of operating costs of ships. This test method is designed as a screening test to evaluate antifouling coating systems under conditions of hydrodynamic stress caused by water flow alternated with static exposure to a fouling environment. A dynamic test is necessary because of the increasing availability of AF coatings that are designed to ablate in service to expose a fresh antifouling surface. Because no ship is underway continually, a static exposure phase is included to give fouling microorganisms the opportunity to attach under static conditions. After an initial 30-day static exposure, alternated 30-day dynamic and static exposures are recommended as a standard cycle. The initial static exposure is selected to represent vessels coming out of drydock and sitting pierside while work is being completed. This gives the paint time to lose any remaining solvents, complete curing, absorb water, and, in general, stabilize to the in-water environment. 5.2 This test method is intended to provide a comparison with a control antifouling coating of known performance in protecting underwater portions of ships’ hulls. This test method gives an indication of the performance and anticipated service life of antifouling coatings for use on seagoing vessels. However, the degree of correlation between this test method and service performance has not been determined.
