For the high pressure CO2 system, especially for the distrIbution pipe system. What is the pressure test requirement according to NFPA? What is the test pressure value and shall we do air pressure test or water pressure test？
Not seeing any piping test required?
You can view NFPA 12 for free
OHHH I am not an engineer, so you can discount my reply if you want, and I cannot do math.
Cda comments were fair enough on the subject matter.
What is the pressure test requirement according to NFPA?
Here is the 2015 NFPA 12 requirements for the approval of the installations for marine systems. Other systems may require different testing as directed by the AHJ.

Helpful website information for testing the marine systems at CO2 Flooding System - Fixed Fire Fighting on Ships
It give you ideas where a test pressure valve should be located.
Thanks Milton for your comments.
This is for marine systems,, what about non marine systems ?
The only thing I could find is the AHJ requirements for a system discharge test for other than marine systems. The test would pressure up the distribution piping revealing any failures.
