本标准建立了一种测试方法，用于测量快速试验对弹性材料的影响 在干燥的二氧化碳环境中，由于压力升高而减压。它是为测试O形圈或其他密封圈而设计的 弹性硫化橡胶的样品。本试验方法不适用于多孔橡胶或多孔材料的试验。本标准建议了试样制备程序、使用的试验设备、遵循的试验程序以及试验结果报告。通过监测物理和机械性能的变化以及暴露于选定试验介质后外观的变化来确定结果。

This standard establishes a test method to measure the effect on elastomeric materials subjected to rapid depressurization from elevated pressures in dry CO2 environments. It is designed for testing O-rings or other specimens of elastomeric vulcanizates. This test method is not applicable to the testing of cellular rubber or porous materials.This standard recommends procedures for the preparation of test specimens, the test equipment to be used, the test procedures to be followed, and the reporting of test results. The results are determined by monitoring changes in physical and mechanical properties as well as changes in appearance after exposure to the selected test media.
