本试验方法规定了在规定的时间和温度条件下，将代表燃气轮机发动机所用弹性体材料的弹性体材料（AS 568-214尺寸的O形圈）试样暴露在润滑剂或参考流体中的程序。该测试包括悬挂式和压缩式O型环。测量O型环物理性能（拉伸强度、伸长率、硬度、质量、体积和压缩永久变形）的结果变化，以确定弹性体的劣化程度。

This test method provides procedures for exposing specimens of elastomer materials (AS 568-214 size O-rings) representative of those used in gas turbine engines to lubricants or reference fluids under defined time and temperature conditions. This test includes both suspended and compressed O-rings. Resultant changes in the O-ring's physical properties (tensile strength, elongation, hardness, mass, volume, and compression set) are measured to determine the amount of deterioration of the elastomer.
