For CO2 hose assemblies, what is the higher pressure used for testing?

The appropriate higher pressure used for testing CO2 hose assemblies is 300 psi. Testing at this pressure ensures that the hoses can withstand the intended operational pressures without risking leaks or failure under the stress that they may encounter during use.

Using a pressure of 300 psi during testing aligns with safety standards and practices, confirming that the hose assemblies are durable enough for their intended function. This testing process is crucial for ensuring that all components associated with CO2 extinguishing systems are reliable and safe for use in emergencies. Proper pressure testing helps mitigate risks and ensures compliance with industry norms and regulations.
