1.1 These test methods cover procedures for testing and locating the sources of gas leaking at the rate of 4.5 X 10 -14 mol/s (1 X 10 -9 Std cm3/s) 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. 1.2 Three test methods are described: 1.2.1 Test Method A -For the object under test capable of being evacuated, but having no inherent pumping capability. 1.2.2 Test Method B -For the object under test with integral pumping capability. 1.2.3 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. 1.3 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. A specific hazard statement can be found in 19.2. |
