1.1 本试验方法包括测量空中应用的分散剂替代物（通常为染色水）在地面或水面上的沉积。描述了获得这些测量值的测试方法，并考虑了分散剂使用方面的结果分析。已经开发了许多技术，本测试方法概述了它们的应用。这些测量可用于确认或验证给定设备组的规格、其正常运行和使用。 1.2 该测试方法适用于直升机或飞机使用的系统。 1.3 该测试方法是与分散剂应用系统相关的四种测试方法之一。指导 F1413/F1413米 封面设计，实践 1460/1460米 包括校准、测试方法 第1738页 包括沉积和指南 F1737/F1737米 包括系统的使用。建议熟悉所有四个标准。 1.4 所述方法存在一些暴露和职业健康问题。由于它们是分散剂配方的函数，因此本试验方法中不讨论这些。进行此类实验的任何人都应咨询分散剂制造商的职业健康专家，了解所使用的预防措施。 1.5 单位- 以国际单位制表示的值应视为标准值。本标准不包括其他测量单位。 1.6 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 3.1 空中应用的分散剂的沉积被定义为接触表面的空中应用分散剂的量；而施用剂量（通常称为施用速率）是递送系统每单位面积释放的材料量。沉积单位为每公顷升或每英亩美国加仑。由于许多原因，沉积可能与应用剂量（单位面积的材料体积）不同，例如，风对喷雾的影响以及分散剂从飞机上释放后的蒸发。 3.2 本试验方法描述了喷雾系统在油上沉积分散剂的能力的测量。本试验方法不适用于泄漏时。这些技术旨在确定新系统开发期间以及系统维修或重大修改后的设备性能。 3.3 使用该测试方法获得的数据可直接与分散剂在浮油上的沉积有关，因此可用于确定分散剂沉积和液滴尺寸。 3.4 替代物沉积和液滴尺寸数据可作为优化分散剂应用设备及其使用的技术基础。 3.5 分散剂替代物的选择可能不同，通常选择水和标记染料。

1.1 This test method covers the measurement of the deposition of an aerially applied dispersant surrogate, typically dyed water, on the surface of the ground or water. The test method of obtaining these measurements is described, and the analysis of the results, in terms of dispersant use, is considered. There are a number of techniques that have been developed, and this test method outlines their application. These measurements can be used to confirm or verify the specifications of a given equipment set, its proper functioning, and use. 1.2 This test method is applicable to systems used with helicopters or airplanes. 1.3 This test method is one of four related to dispersant application systems. Guide F1413/F1413M covers design, Practice F1460/F1460M covers calibration, Test Method F1738 covers deposition, and Guide F1737/F1737M covers the use of the systems. Familiarity with all four standards is recommended. 1.4 There are some exposure and occupational health concerns regarding the methods described. These are not discussed in this test method since they are a function of dispersant formulation. Anyone undertaking such experiments should consult the occupational health experts of the dispersant manufacturer regarding the precautions to be used. 1.5 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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. 1.7 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 ====== 3.1 The deposition of an aerially applied dispersant is defined as the amount of an aerially applied dispersant that contacts the surface; whereas, application dosage (frequently referred to as application rate) is the amount of material that is released per unit area by the delivery system. The units of deposition are litres per hectare or U.S. gallons per acre. The deposition may differ from the application dosage (volume of material per unit area) for many reasons, such as, the effects of wind on the spray and the evaporation of the dispersant after it has been released from the aircraft. 3.2 This test method describes the measurement of the ability of a spray system to deposit a dispersant on oil. It is not intended that this test method be used at the time of a spill. These techniques are intended to determine the equipment performance during the development of new systems and after the repair or significant modification of a system. 3.3 The data obtained from the use of this test method can be directly related to the deposition of dispersant on an oil slick, and thus can serve to determine both the dispersant deposition and the drop size. 3.4 Surrogate deposition and drop size data can be used as a technical basis for the optimization of dispersant application equipment and its use. 3.5 The choice of a dispersant surrogate may vary, typically water is chosen along with a marker dye.
