1.1 本试验方法涵盖了EPA 450/3-8-018第18节中概述的在工厂内喷涂汽车涂料的生产条件下测定转移效率的程序（使用重量法）。 1.2 转移效率是根据喷涂的油漆固体和沉积在喷涂零件上的油漆固体的重量计算得出的。推荐的方法包括直接对零件进行喷漆。还描述了一种用铝箔覆盖零件的替代方法。 1.3 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。 1.4 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。 具体危害说明见 10.1.8.1 。 1.5 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====== 5.1 本试验方法专门针对汽车和轻型卡车车身的喷漆。一般原则适用于其他汽车零部件的涂装。 5.2 该试验方法也可用于测量模拟生产条件和操作的全尺寸涂装设施中的转移效率。

1.1 This test method covers procedures for determination of the transfer efficiency (using a weight method) under production conditions for in-plant spray application of automotive paints as outlined in Section 18 of EPA 450/3-88-018. 1.2 The transfer efficiency is calculated from the weight of the paint solids sprayed and that deposited on the painted part. The recommended approach involves painting the part directly. Also described is an alternative approach for painting parts covered with aluminum foil. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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. Specific hazard statements are given in 10.1.8.1 . 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 ====== 5.1 This test method is specifically directed at the spray painting of automobile car and light duty truck bodies. The general principles are applicable to the painting of other automotive parts. 5.2 This test method may also be used to measure transfer efficiency in full-sized painting facilities simulating production conditions and operations.
