Pneumatic pressure testing is a process to determine the threshold of safe and functional operation for a variety of pressure systems. Unlike hydrostatic pressure testing, which utilizes a liquid medium to exert pressure, pneumatic testing employs the use of a non-flammable gas such as nitrogen or air.

Extra caution must be taken with pneumatic pressure testing. Failures are much more likely to be catastrophic when they do occur and damage to test subjects can be extensive. Pneumatic pressure tests are used primarily to prove the efficacy of seals and should never be used as a burst test.
