1.1 本试验方法包括在受控的实验室条件下对喷涂涂层的转移效率进行评估和比较。 1.2 该试验方法已被证明能产生良好的实验室内再现性。实验室间的精度较差，并且在很大程度上取决于喷漆室中严格控制的气流、油漆输送到零件的速率以及测试方法中建议的其他变量。 1.3 限制: 1.3.1 该实验室程序仅指示喷雾变量对传输效率的影响方向。影响的大小仅由特定的工厂经验决定。 注1: 此实验室程序需要特定的设备和程序。对于那些无法获得所需设备类型的实验室，正在制定更通用的实验室程序作为程序B。 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。 有关具体危险说明，请参阅第节 7. 和 8.11.9 和 8.13.2 。 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====== 5.1 根据上述限制，该程序可作为一种研究工具，用于优化喷涂设备和涂料配方，以及研究改变操作变量、喷涂设备和涂层类型对转移效率的相对影响。

1.1 This test method covers the evaluation and comparison of the transfer efficiency of spray-applied coatings under controlled laboratory conditions. 1.2 This test method has been shown to yield excellent intralaboratory reproducibility. Interlaboratory precision is poorer and is highly dependent on closely controlled air flow in the spray booth, the rate at which the paint is delivered to the part, and other variables suggested in the test method. 1.3 Limitations: 1.3.1 This laboratory procedure only indicates the direction of the effect of spray variables on transfer efficiency. The magnitude of the effect is determined only by specific plant experience. Note 1: This laboratory procedure requires specific equipment and procedures. For those laboratories that do not have access to the type of equipment required a more general laboratory procedure is being prepared as Procedure B. 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. For specific hazard statements, see Section 7 and 8.11.9 and 8.13.2 . 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 above, the procedure can be used as a research tool to optimize spray equipment and paint formulations as well as to study the relative effect on transfer efficiency of changing operating variables, spray application equipment, and types of coatings.
