1.1 本试验方法涵盖了在实验室中确定溢油分散剂对各种油的有效性的程序。本试验方法不适用于其他化学试剂，也不适用于在开阔水域使用此类产品或分散剂。 1.2 本试验方法涵盖了旋转瓶试验装置的使用，不包括其他装置，本报告中描述的分析程序也不直接适用于此类程序。 1.3 使用本试验方法获得的试验结果旨在提供基线有效性值，用于在类似于试验中使用的条件下比较分散剂和油类型。 1.4 使用本试验方法获得的试验结果是有效性值，应引用为本标准试验得出的试验值。分散剂有效性值与海上或其他装置中的有效性没有直接关系。海上的实际有效性取决于海洋能量、石油状态、温度、盐度、实际分散剂用量以及与石油相互作用的分散剂量。 1.5 在油上使用或不使用分散剂的决定不应仅基于此或任何其他实验室测试方法。 1.6 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.7 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。 1.8 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 需要进行标准测试，以建立基线性能参数，以便比较分散剂，比较给定分散剂对不同油的有效性，以及在不同油风化阶段的有效性，并检查分散剂批次或油的有效性随时间或其他因素的变化。该测试方法在低混合能量下进行测试，当分散剂功效较高时，该测试方法有助于区分变量之间有效性的细微变化。一种更高能量的试验替代方法是挡板烧瓶（试验方法 F3251 ). 5.2 分散剂的有效性因石油类型、海洋能源、石油条件、盐度和许多其他因素而异。 本试验方法的试验结果构成基线，但不能作为海上性能的绝对测量值。实际现场有效性可能大于或小于该值。 5.3 世界各地已经开展了许多分散剂试验。该测试是多年来开发的，使用全球测试的结果，使用标准化设备、测试程序，并克服其他测试程序中指出的困难。

1.1 This test method covers the procedure to determine the effectiveness of oil spill dispersants on various oils in the laboratory. This test method is not applicable to other chemical agents nor to the use of such products or dispersants in open waters. 1.2 This test method covers the use of the swirling flask test apparatus and does not cover other apparatuses nor are the analytical procedures described in this report directly applicable to such procedures. 1.3 The test results obtained using this test method are intended to provide baseline effectiveness values used to compare dispersants and oil types under conditions analogous to those used in the test. 1.4 The test results obtained using this test method are effectiveness values that should be cited as test values derived from this standard test. Dispersant effectiveness values do not directly relate to effectiveness at sea or in other apparatuses. Actual effectiveness at sea is dependent on sea energy, oil state, temperature, salinity, actual dispersant dosage, and amount of dispersant that interacts with the oil. 1.5 The decision to use or not use a dispersant on an oil should not be based solely on this or any other laboratory test method. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 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. 1.8 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 A standard test is necessary to establish a baseline performance parameter so that dispersants can be compared, a given dispersant can be compared for effectiveness on different oils, and at different oil weathering stages, and batches of dispersant or oils can be checked for effectiveness changes with time or other factors. This test method provides a test at low mixing energy that is useful for discriminating subtle changes in effectiveness between variables when dispersant efficacy is high. A higher energy test alternative is the Baffled Flask (Test Method F3251 ). 5.2 Dispersant effectiveness varies with oil type, sea energy, oil conditions, salinity, and many other factors. Test results from this test method form a baseline, but are not to be taken as the absolute measure of performance at sea. Actual field effectiveness could be more or less than this value. 5.3 Many dispersant tests have been developed around the world. This test has been developed over many years using findings from world-wide testing to use standardized equipment, test procedures, and to overcome difficulties noted in other test procedures.
