1.1 这些试验方法包括在一般工厂条件下测定喷涂涂层的转移效率。转移效率是指喷涂过程中沉积的油漆固体与使用的油漆固体总量的比率，以百分比表示。 1.2 转移效率根据喷涂的油漆固体的重量或体积以及沉积在涂漆零件上的油漆固体的重量或体积计算。 1.3 局限性包括准确确定沉积在零件上的油漆固体量的能力，以及准确测量喷涂油漆量的能力。 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。 注1: 这些试验方法适用于一般工厂生产设备和程序。测试方法中定义了一种特定于汽车工厂的方法 D5066 . 注2: 汽车和轻型卡车面漆操作中挥发性有机化合物排放率和转移效率之间的关系，EPA 450/3-88-01，参考试验方法 D5066 不适用于一般生产设施。 注3: 单点传输效率测量可能无法代表整个过程。 注4: 传输效率测量期间，操作员和喷涂设备的操作条件应代表正常操作条件。 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。 有关具体的危险说明，请参阅第节 7. 和 10.3.1 . 注5: 联邦监管机构尚未采用这些测试方法来证明其符合空气污染法规，如VOC、HAPS等。 1.6 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 受中列出的限制 1.3 ，这些测试方法可用于优化油漆应用过程。

1.1 These test methods cover the determination of the transfer efficiency of spray-applied coatings under general plant conditions. Transfer efficiency is the ratio of paint solids deposited to the total paint solids used during the application process, expressed as a percent. 1.2 The transfer efficiency is calculated from the weight or volume of the paint solids sprayed and that of the paint solids deposited on the painted part. 1.3 Limitations include the ability to accurately determine the amount of paint solids deposited on the part and the capability of accurate measurement of the amount of paint sprayed. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. Note 1: These test methods apply to general plant production equipment and procedures. A method specific to automotive plants is defined in Test Method D5066 . Note 2: The relationship between volatile organic compound emission rates and transfer efficiency in automobile and light duty truck topcoat operations, EPA 450/3-88-01, referenced in Test Method D5066 does not apply to general production facilities. Note 3: A single-point transfer efficiency measurement may not represent the entire process. Note 4: The operator and the spray-application equipment-operating conditions during the transfer efficiency measurement should be representative of normal operating conditions. 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. For specific hazard statements see Section 7 , and 10.3.1 . Note 5: These test methods have not been adopted by federal regulatory agencies for demonstration of compliance with air pollution regulations such as VOC, HAPS, etc. 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 ====== 5.1 Subject to the limitations listed in 1.3 , these test methods can be used to optimize paint application processes.
