标准摘要
[中文适用范围]： 本国际标准规定了在潮湿条件下测定柔性多孔材料压缩永久变形的方法。 该方法包括将试件保持在规定的时间、温度、湿度和恒定压缩应变的条件下，并在规定的恢复期后确定对试件厚度的影响。 [外文原描述]： This International Standard specifies a method for determining the compression set of flexible cellular materials under humid conditions. This method consists of maintaining the test piece under specified conditions of time, temperature, humidity and constant compressive strain and determining the effect on the thickness of the test piece after a specified recovery period.
