1.1 本试验方法描述了可用于输送至挥发性有机化合物控制装置的水性汽车涂料中挥发性有机化合物（VOC）释放量的测定。通过测量经过蒸发或干燥的新涂层试板的重量损失以及通过分析涂层中的VOC或水含量来完成测定。 1.2 本试验方法适用于在模拟生产过程或实际生产设施中喷涂油漆后，从喷涂和烘焙操作中释放的VOC。 1.3 确定VOC的其他几种方法的符号和计算: 实践 第3960页 ，EPA 450/3-8-018和EPA 450/38-0419已纳入本试验方法。本试验方法中使用的大多数符号和计算都是独特的，因为本试验方法独特地处理了经过干燥、固化或添加溶剂的油漆样品的重量差异。 注1: 对被评估产品的培训和知识对于从该测试方法中获得有意义的数据至关重要。建议进行几次实践运行，并在对试样进行此测试之前评估实验室的可重复性。 1.4 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。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 4.1 该测试方法提供了可用于确定输送至VOC控制装置入口的VOC量的基本工程数据。该程序有助于确定在闪蒸区或烘烤炉中从涂层中析出并可用于焚烧的VOC的量，尽管在使用其他形式的VOC减排时也可以遵循相同的程序。 4.2 VOC控制装置从工艺中去除的VOC总量是由该测试方法给出的可用量与控制装置的VOC去除效率相结合的函数。

1.1 This test method describes the determination of the amount of volatile organic compound (VOC) released from applied waterborne automotive coatings that is available for delivery to a VOC control device. The determination is accomplished by measuring the weight loss of a freshly coated test panel subject to evaporation or drying and by analysis of the VOC or water content in the coating. 1.2 This test method is applicable to the VOC released from application and baking operations after the paint has been applied in a simulation of a production process, or in an actual production facility. 1.3 Symbols and calculations from several other methods that determine VOC: Practice D3960 , EPA 450/3-88-018 and EPA 450/3-84-019 have been incorporated into this test method. The majority of symbols and calculations used in this test method are unique because this test method deals uniquely with differences in weight of applied paint samples that have been subject to drying, curing or solvent addition. Note 1: Training and knowledge of the product being evaluated are essential for obtaining meaningful data from this test method. It is recommended that several practice runs be performed, and the laboratories repeatability evaluated before performing this test on the test samples. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 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. 1.6 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 ====== 4.1 This test method provides basic engineering data that may be used to determine the amount of VOC delivered to the inlet of a VOC control device. The procedure is useful for establishing the quantity of VOC that is evolved from the coating in the flash zone or bake oven and available to be incinerated, although the same procedure can be followed when other forms of VOC abatement are used. 4.2 The total amount of VOC removed from the process by the VOC control device is a function of the amount available as given by this test method combined with the VOC removal efficiency of the control device.
