Standard Test Method for Determination of Conductive Deposits of Electrical and Mechanical Components from Fluids in Liquid and Vapor States within an Electrically Charged System 带电系统内液体和蒸气状态流体中电气和机械部件导电沉积物测定的标准试验方法
发布日期: 2024-03-01
1.1 本测试方法涵盖了导电沉积物测试的基本操作。该装置用于监测树枝状物和沉积物的形成,这些树枝状物是导电的,并且可以在电动汽车和涉及电子产品的其他行业中使用的流体的氧化条件下形成。氧化条件可以在80 °C至180 °C,带有非常特殊的电路板,在通电的情况下,监测电导随时间的变化。随着时间的推移,对液体和蒸汽区域都进行了监测。温度、电压和时间的变量可以根据行业需要进行更改。 可以实现基于沉积物形成速率的报告的指数。典型测试在150 °C,持续时间高达500 h,并施加监测电压。 注1: 测试多达1000 h具有一定的历史意义,是一个选项,但未包含在本测试方法中。 1.2 这种测试方法具有临时精度。该测试方法的实验室间研究正在进行中,预计2024年12月或之前将提供完整的精度声明。 1.3 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.4 本标准并不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。 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 该方法可用于评估流体在电动车辆传动系统和其他动力或腐蚀性应用中的适用性,以与铜或其他材料形成导电沉积物和腐蚀趋势。已知在现场表现不佳的流体已被证明未通过该测试,而已知在现场性能良好的流体已通过该测试。使用该测试对流体进行比较可能是指示哪些流体可能具有更好的现场性能的指标。SAE J3200《汽车电气传动系地面车辆信息报告流体》建议进行此试验。
1.1 This test method covers the basic operation of the conductive deposit test. The apparatus is utilized to monitor the formation of dendrites and deposits that are conductive and may form under oxidation conditions of fluids used in electric vehicles and other industries where electronics are involved. The oxidation conditions can vary from 80 °C to 180 °C with very specific circuit boards, under power, and monitoring changes in conductance over time. Both the liquid and vapor areas are monitored for this condition over time. Variables in temperature, voltage, and time can be altered according to the industry need. A reported index based on the rate of deposit formation may be implemented. The typical testing is performed at 150 °C over a period of up to 500 h with a monitored voltage applied. Note 1: Testing up to 1000 h has some historical significance and is an option but not covered in this test method. 1.2 This test method has an interim precision. An interlaboratory study of this test method is being conducted and a complete precision statement is expected to be available on or before December 2024. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 ====== 5.1 This method may be utilized to assess the suitability of a fluid for use in electric vehicle drivelines and other powered or corrosive applications to form conductive deposits and corrosion tendencies with copper or other materials. Fluids known to perform poorly in the field have been shown to fail this test and fluids known to perform well in the field have been shown to pass this test. Comparison of fluids using this test is likely to be an indicator of which fluids may have better field performance. This test is recommended in the SAE J3200, Surface Vehicle Information Report Fluid for Automotive Electrified Drivetrains.
