ASTM-A1047 › Standard Test Method for Pneumatic Leak Testing of Tubing
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method provides procedures for the leak testing of tubing using pneumatic pressure. This test method involves measuring the change in pressure inside the tubing over time. There are three procedures that may be used, all of which are intended to be equivalent. It is a qualitative not a quantitative test method. Any of the three procedures are intended to be capable of leak detection and, as such, are intended to be equivalent for that purpose.
1.2 The procedures will produce consistent results upon which acceptance standards can be based. This test may be performed in accordance with the Pressure Differential (Procedure A), the Pressure Decay (Procedure B), or the Vacuum Decay (Procedure C) method.
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 determine the applicability of regulatory limitations prior to use.
1.3 The values stated in either inch-pound or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
Significance and Use
When permitted by a specification or the order, this test method may be used for detecting leaks in tubing in lieu of the air underwater pressure test.
