1.1 本试验方法包括测定可交付至挥发性有机化合物控制装置的所用溶剂型汽车涂料释放的挥发性有机化合物（VOC）的量。这是通过在生产过程的实验室模拟中测量经过溶剂蒸发或烘烤的新涂层试板的重量损失来实现的。 1.2 本试验方法适用于油漆涂覆后闪蒸和烘烤操作释放的挥发性有机化合物。 1.3 本试验方法适用于溶剂型汽车涂料，旨在表示或模拟生产过程。相同的一般原则适用于含有挥发性有机化合物（VOC）的水性涂料，尽管本文没有提供具体的程序细节来区分VOC和水。 1.4 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。 1.5 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====== 4.1 本试验方法提供了基本工程数据，可用于确定VOC控制装置（尤其是汽车行业）入口处可交付的VOC量。 6. 通常，该程序有助于确定从烘箱中的涂层中析出并可用于焚烧的挥发性有机化合物的数量，尽管对于其他形式的挥发性有机化合物减排（即碳、吸附等）也可以遵循相同的程序。 4.2 如果能够充分控制所有关键因素（例如，温度、清洁度、振动、可接近性等），则本试验方法可适用于直接在生产环境中使用。 4.3 VOC控制装置从工艺中去除的VOC总量是本试验方法给出的可用量与控制装置的VOC去除效率的函数。

1.1 This test method covers the determination of the amount of volatile organic compound (VOC) released from applied solventborne automotive coatings that is available for delivery to a VOC control device. This is accomplished by measuring the weight loss of a freshly coated test panel subjected to solvent evaporation or baking in a laboratory simulation of the production process. 1.2 This test method is applicable to the VOC released from flashoff and baking operations after the paint has been applied. 1.3 This test method is applicable to solventborne automotive coating materials and is intended to represent or simulate the production process. The same general principles apply to waterborne coatings that contain volatile organic compounds (VOC), although specific procedural details are not presented herein to differentiate between VOC and water. 1.4 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. 1.5 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 available for delivery at the inlet of a VOC control device (particularly for the automobile industry). 6 Typically, the procedure is useful for establishing the quantity of VOC that is evolved from the coating in the baking oven and available to be incinerated, although the same procedure can be followed for other forms of VOC abatement (that is, carbon, adsorption, etc.). 4.2 This test method may be adaptable for use directly in a production environment if all the critical factors (for example, temperature, cleanliness, vibration, accessibility, etc.) can be adequately controlled. 4.3 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.
