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 airborn ultrasonic technique.
1.2 In general practice this should be limited to leaks producing leakage of 4.5 X 10 -7 m /s (10 atm[dot]cm /s at 0°C) or more. Refer to Guide E 432 for additional information.
1.3 Test Method B, Ultrasonic Transmitter- For 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.
1.4The values stated in SI units are to be regarded as the standard.
1.4 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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
