scope:

1.1 Test Method A, Pressurization- This test method covers procedures for calibration of ultrasonic instruments, location, and estimated measurements of gas leakage to atmosphere by the airborne ultrasonic technique.²

1.2 In general practice this should be limited to leaks detected by two classifications of instruments, Class I and Class II. Class I instruments should have a minimum detectable leak rate of 6.7 10 7 mol/s (1.5 10 2 std. cm3/s at 0C) or more for the pressure method of gas leakage to atmosphere. Class II instruments should have a minimal detectable leak rate of 6.7 106 mol/s (1.5 10 1 std. cm3/s at 0C) or more for the pressure method of gas leakage to atmosphere. Refer to Guide E 432 for additional information.

1.3 Test Method B, Ultrasonic TransmitterFor object under test not capable of being pressurized but capable of having ultrasonic tone placed/injected into the test area to act as an ultrasonic leak trace source.

1.3.1 This test method is limited to leaks producing leakage of 6.7 106 mol/s (1.5 10 1 std. cm3/s at 0C) or greater.

1.4 The values stated in SI units are to be regarded as the standard.

1.5This 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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
