What is the minimum pressure testing requirement for hose assemblies before use?

• A. At service pressure
• B. Twice the service pressure
• C. Equal to service pressure
• D. Three times the service pressure

Answer: (B)

The minimum pressure testing requirement for hose assemblies before use is twice the service pressure. This standard is set to ensure that the hose can withstand the higher pressures that may occur in operational conditions without failure. Testing at this elevated pressure helps identify any weaknesses or defects in the hose material or construction that could lead to hazards during normal use. By verifying the integrity of the hose at twice the service pressure, it significantly enhances safety, reduces the risk of failure, and ensures compliance with industry standards. Using this precautionary measure helps maintain dependable operations in systems utilizing compressed natural gas.
