at / with / under pressure - which preposition is correct?

[JACEK1]

Hello again!

When writing about various pressure tests, I often worry about which preposition to use.

For example:

The cooler was subjected to a leakage test under air pressure of .......

The cooler was subjected to a leakage test with air pressure of .......

The cooler was subjected to a leakage test at air pressure of .......

What do you think?

Thank you.

I'd use 'under'.

I think "at" would work also.
