ISO 2782:2006描述了在稳态条件下测量橡胶对气体渗透性的两种程序。一个使用水平测量装置进行恒压测量，另一个使用垂直测量装置进行恒容或恒压测量。如果橡胶是均质和各向同性的，通过这些程序获得的结果可外推至不同于试样的材料厚度。本程序适用于硬度不低于35 IRHD的固体橡胶，以及空气、氮气、氧气、氢气、液化石油气（气态）和煤气等气体。如果使用的气体使被测橡胶明显膨胀，则可能会产生误差。

ISO 2782:2006 describes two procedures for measuring the permeability of rubber to gases under steady-state conditions. One uses a horizontal measuring device for measurements at constant pressure and the other uses a vertical measuring device for measurements at constant volume or constant pressure. The results obtained by these procedures may be extrapolated to thicknesses of material different from that of the test piece providing the rubber is homogeneous and isotropic.The procedures apply to solid rubber of hardness not less than 35 IRHD and to gases such as air, nitrogen, oxygen, hydrogen, liquefied petroleum gas (in gaseous form) and coal gas. Errors may be introduced if the gas used appreciably swells the rubber under test.
