第2部分:试验方法试验XC:流体污染

范围

GB/T2423的本部分规定了评定零部件、设备或其组成材料(以下指试验样品)经受流体意外接触

影响的试验方法。

本部分所列流体代表了在使用过程中经常能遇到的流体。试验样品不必暴露在所列的所有或部分

流体中，所列流体也不完全。试验所用流体若非本部分所列，相关规范应将其列出。附录A对试验流

体、试验样品和严酷等级的选择提供了指导信息。

本试验不适用于验证与流体持续接触的零部件或设备的工作适应性，例如浸渍的燃料泵，也不适用

于验证耐电解腐蚀的能力。

2规范性引用文件

下列文件中的条款通过GB/T2423的本部分的引用而成为本部分的条款。凡是注日期的引用文

件，其随后所有的修改单(不包括勘误的内容)或修订版均不适用于本部分，然而，鼓励根据本部分达成

协议的各方研究是否可使用这些文件的最新版本。凡是不注日期的引用文件，其最新版本适用于本

部分

ISO1817:1985硫化橡胶—流体影响的测定

试验流体

3.1试验流体的规定

相关规范(见第12章)应规定所需的试验流体。试验流体尽可能从表1中选择，每种流体都特定地

代表了某一类流体(参见第A.2章)

当试验添加了表1未列流体时，相关规范也应加以明确。

3.2注意事项

由于某些流体的闪点在试验温度范围内，所以应确保采取足够的安全措施以减少火灾或爆炸的可

能性。某些流体本身或与其他流体或试验样品混合后变得有毒，在开始试验前应适当考虑这种可能性

极力建议咨询有关健康和安全的专家
