ASTM F 2378:2005

1.1 This test method covers a means of evaluating the sealing properties of sheet, composite, and solid form-in-place gasket materials (see Classification F 104 or F 868) 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. 1.2 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. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
