Halon 1301 systems are tested under pressure for 10 minutes at 150 psi in increments of how many psi to reach 150 psi?

Halon 1301 systems are tested under pressure for 10 minutes at 150 psi in increments of how many psi to reach 150 psi?

• A. 25 psi
• B. 50 psi
• C. 75 psi
• D. 100 psi

Answer: (B)

When testing pressure up to a final target, you raise the pressure in fixed, equal steps so you can monitor how the system reacts at each level. Reaching 150 psi with 50 psi increments gives a straightforward sequence: 50, then 100, then 150. This provides clear checkpoints and keeps the ramp predictable, which is why it’s the standard approach for this test. After reaching 150 psi, you hold there for 10 minutes to evaluate performance at the final pressure. Other step sizes either involve more steps or create nonuniform increases, which makes the process less consistent with typical procedures.
