NGA 2000 CLD
If there is a leakage, then proceed as follows:
a)Using Helium (He) for test medium
•Supply Analyzer Module with the test medium with a pressure of approx. 2,000 hPa (15 psig).
•Look for the leak with a helium leak detector.
b)Using Nitrogen (N2) for test medium
•Supply Analyzer Module with the test medium with a pressure of approx. 2,000 hPa (15 psig).
•Liberally cover all fittings, seals, and other pos- sible sources of leakage with a suitable leak test liquid such as SNOOP. Bubbling or foam- ing indicates leakage.
•Remove the source of leak.
•Perform a leakage test once more as decribed obove.
