ASTM International Standard Test Method for Hydrostatic Leak Testing ASTM E1003-95(2000)

1.1 This test method covers the testing of components for leaks by pressurizing them inside with a liquid. 1.2 This test method can be used on piping, valves, and containers with welded or fitted sections which can be sealed at their ends and which are designed for internal pressure. 1.3 Basic procedures are described based on the type of inspection used. These procedures should be limited to finding leakage indications of 4.5 X 10 -9 mol/s (1 X 10 -4 Std cm /s) or larger. 1.4 The values stated in SI units are to be regarded as the standard. 1.5 This standard does not purport to address 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 determine the applicability of regulatory limitations prior to use.
