Full discharge test shall be performed:

A full discharge test checks that the entire CO2 fire suppression system actually releases and distributes the agent as designed when it discharges, confirming that the cylinders, valves, piping, nozzles, and the control/activation systems all work together and that the protected space reaches the required agent concentration in the expected time. This is why it’s performed on each installed CO2 system: every installation can have slight differences in components or setup that affect performance, so testing every system ensures no hidden fault goes undetected and that the system will perform reliably when needed. Doing the test only during initial commissioning wouldn’t verify ongoing performance after installation, and saying it isn’t required or that it’s only for high-risk installations doesn’t align with standard practice, as all installed CO2 systems should be verified to ensure safety and effectiveness.
