Gas pressure test: N2 and air, differences in leak detection capability
There really isn’t such a concept. In industrial facilities, the pressure of the inert gas nitrogen is higher than that of air, and many devices require nitrogen to displace air (oxygen) before they can be put into operation.
This is a airtightness test. . . . It’s not a pressure test.
Leaks in air and nitrogen are detected using soap bubbles. . . Equivalent effect
