1.1本试验方法包括使用石墨炉原子吸收分光光度法（GF-AAS）在实验室测定合成海水中防污涂层中铜的释放速率。 1.2本程序包含测定防污涂料中铜浸出率的准备步骤，包括仪器、试剂、储罐条件和采样点细节。分析海水中的铜浓度需要在低十亿分之一（ppb）水平上准确测定铜。 为了检测和校正试剂杂质，需要可接受的分析精度标准。因此，分析方法的定量限应为6 ppb或更少。灵敏度最高的最常用仪器的选择方法是GF-AAS。编写本程序的目的是包括将铜与海水隔离的必要步骤，从而提高灵敏度并消除干扰原子吸收技术使用的盐类。 1.3其他分析方法可根据需要进行适当的程序更改，以适应所选的特定方法。此类方法必须满足第节所述的定量限（6 ppb） 1.4本试验方法尚未验证，以反映防污产品的原位铜释放率，因此目前不应在生成环境风险评估的过程中使用。防污（AF）涂层的在役释放率预计会随着海水化学、温度和水动力状态的自然变化而变化。 1.5以国际单位制表示的数值应视为标准值。括号中的英寸-磅单位仅供参考。 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规程，并确定监管限制的适用性。 有关具体的危险说明，请参阅第节。

1.1 This test method covers the laboratory determination of the rate at which copper is released from an antifouling coating in synthetic seawater using graphite furnace atomic absorption spectrophotometry (GF-AAS). 1.2 The procedure contains the preparation steps for the leach rate determination of copper from antifouling paints including apparatus, reagents, holding tank conditions, and sampling point details. Analysis for the concentration of copper in seawater requires the accurate determination of copper at the low parts per billion (ppb) level. To detect and correct for reagent impurities, acceptable analytical precision standards are necessary. Therefore, the limit of quantitation for the analytical method should be 6 ppb or less. The method of choice for most commonly available instrument with the greatest sensitivity would be GF-AAS. This procedure is written to include necessary steps to isolate the copper from seawater, thereby increasing sensitivity and eliminating salts that interfere with the use of atomic absorption techniques. 1.3 Other analytical methods may be utilized with appropriate procedural changes, as needed, to accommodate selectd specific methods. Such methods must meet the limit of quantition (6 ppb) as presented in Section 1.4 This test method has not yet been validated to reflect in-situ copper release rates for antifouling products and therefore should not, at present, be used in the process of generating environmental risk assessments. In-service release rates of antifouling (AF) coatings are expected to vary with natural variability in seawater chemistry, temperature, and hydrodynamic regime. 1.5 The values stated in SI units are to be regarded as standard. The inch-pound units given in parentheses are for information only. 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 practices and to determine the applicability of regulatory limits prior to use.
