1.1 These test methods cover procedures for testing the sources of gas leaking at the rate of 4.4 10 14 moles/s (1 109 standard-cm 3/s at 0C) or greater. These test methods may be conducted on any object that can be evacuated and to the other side of which helium or other tracer gas may be applied. The object must be structurally capable of being evacuated to pressures of 0.1 Pa (approximately 103 torr).
1.2 Three test methods are described;
1.2.1 Test Method AFor the object under test capable of being evacuated, but having no inherent pumping capability.
1.2.2 Test Method BFor the object under test with integral pumping capability.
1.2.3 Test Method CFor 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 (LD).
1.3 The values stated in SI units are to be regarded as standard. The values given in brackets are for information only.
