SAE J1950 在试验场上的车辆腐蚀试验


适用范围
The facilities used by domestic automotive manufacturers to provide accelerated corrosion aging of complete vehicles are described in general. The types of vehicles tested, general test methodology, and techniques used to determine test-to-field correlation are discussed. The different procedures used throughout the industry produce different results on various vehicle coatings, components, and systems. The key to successful interpretation of test results is a thorough understanding of the corrosion mechanisms involved and the effects of test limitations on these mechanisms. The purpose of this information report is to provide a general overview of some proving ground procedures and facilities used in the United States to evaluate the corrosion protection performance of vehicles. Because of limitations involved with any accelerated testing procedure, and despite the use of complete vehicles and attempts to make test environments all-inclusive, test results require knowledgeable interpretation. Proving grounds are, in effect, large laboratories. As with different laboratory test procedures, different test techniques will produce different results. Consideration of the various techniques and analysis tools discussed in the following sections may give the reader an understanding of the environments that vehicles must be designed to survive and may aid in the further development of accelerated corrosion tests.

概述了国内汽车制造商用于加速整车腐蚀老化的设施。讨论了试验车辆的类型、一般试验方法以及用于确定试验与现场相关性的技术。整个行业使用的不同程序对各种车辆涂层、部件和系统产生不同的结果。成功解释试验结果的关键是彻底了解所涉及的腐蚀机制以及试验限制对这些机制的影响。本信息报告的目的是对美国用于评估车辆防腐性能的一些试验场程序和设施进行概述。由于任何加速试验程序都存在局限性,尽管使用了整车,并试图使试验环境包罗万象,但试验结果需要有知识的解释。事实上,试验场是大型实验室。正如不同的实验室测试程序一样,不同的测试技术将产生不同的结果。考虑以下章节中讨论的各种技术和分析工具,可使读者了解车辆必须设计为能够生存的环境,并有助于加速腐蚀试验的进一步发展。
