ASTM F 2378 - 05 (Reapproved 2016) Standard Test Method for Sealability of Sheet, Composite, and Solid Form-in-Place Gasket Materials

Current edition approved Oct. 1, 2016. Published October 2016. Originally approved in 2005. Last previous edition approved in 2011 as F2378 – 05 (2011). — 6 p.
This test method covers a means of evaluating the sealing properties of sheet, composite, and solid form-in-place gasket materials (see Classification F104 or F868) at room temperature, and may be used for fluid (gas or liquid) leak rate measurements. It utilizes relatively short hold times and is not intended to predict long-term performance in application.
This test method is suitable for evaluating the sealing characteristics of a gasket material under different press loads by measuring the leakage rate. This test method may be used as an acceptance test when the producer and user have agreed to specific test conditions for the following parameters: (1) test medium, (2) internal pressure of the medium, (3) press load on the gasket specimen, and (4) the surface finish of the platens.
