What is the exact test pressure and duration for the wildland hose test?

• A. 180 psi for 7 minutes
• B. 210 psi for 5 minutes
• C. 200 psi for 5 minutes
• D. 210 psi for 5 minutes

Answer: (C)

In wildland hose testing, hoses are pressurized to a fixed standard and held there for a set time to verify they can maintain integrity under typical operating stress. The exact test pressure and duration are 200 psi for 5 minutes. This combination is chosen because it provides enough stress to reveal leaks or weak spots without risking damage from excessive pressure, and five minutes is long enough to expose slow leaks or material weaknesses. Other options don’t fit the standard: 180 psi is below the required test stress and wouldn’t adequately challenge the hose; 210 psi is higher than the documented test limit and could cause unnecessary damage; 210 psi for 5 minutes is likewise more demanding than the standard.
