Organization: ASTM
Publication Date: 1 July 2011
Status: active
Page Count: 5
ICS Code (Non-destructive testing): 19.100
scope:

This practice covers procedures for testing and locating the sources of gas leaking at the rate of 1 × 10−8 Pa m3/s (1 × 10−9 Std cm3/s)3 or greater. The test may be conducted on any object to be tested that can be evacuated and to the other side of which helium or other tracer gas may be applied.

Three test methods are described:

Test Method A-For the object under test capable of being evacuated, but having no inherent pumping capability.

Test Method B-For the object under test with integral pumping capability.

Test Method C-For the object under test as in Test Method B, in which the vacuum pumps of the object under test replace those normally used in the leak detector.

Units-The values stated in either SI or std-cc/sec units are to be regarded separately as standard. The values stated in each system may not be exact equivalents: therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

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.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3 The gas temperature is referenced to 0°C. To convert to another gas reference temperature, Tref, multiply the leak rate by (Tref + 273) ⁄273.
