Standard Test Method for Sealability of Sheet, Composite, and Solid Form-in-Place Gasket Materials

Importancia y uso:

5.1 This test method is designed to compare sealing characteristics of gasket materials under controlled conditions by providing a precise measure of leakage rate at different press loads up to 32 MPa (4640 psi).

5.2 This test method is suitable for measuring leakage rates from 0.1 mL/min to as high as 5 L/min for gases.

5.3 This test method evaluates leak rates after time periods (typically 30 min) that result in a steady state leakage rate condition. Holding gasket materials under load and internal fluid pressure until steady state is achieved is required to obtain reproducible results.

5.4 If the fluid being used in the test causes changes, such as swelling, in the gasket material, it may affect results and diminish repeatability.
