1.1 These test methods cover procedures for detecting the sources of gas leaking at the rate of 4.5 X 10^-9 mol/s (1 X 10^-4 standard cm³/s) or greater. The tests may be conducted on any object that can be pressurized with a tracer gas that is detectable by a thermal conductivity detector. The test sensitivity will vary widely depending on the tracer gas used.
