Which two tests must be performed by the manufacturer if NFPA 1901 requirements are included in the apparatus bid specifications?

• A. Brake test
• B. Emissions test
• C. Noise test
• D. Road and hydrostatic test

Answer: (D)

NFPA 1901 requires in-plant testing by the manufacturer to show the apparatus is safe and ready for use, covering both how it performs on the road and how its water system holds up under pressure. The road test evaluates driving performance and operational behavior under real conditions—braking, steering, acceleration, handling, and overall drivability—so you know the vehicle will perform safely on scene. The hydrostatic test checks the water system by pressurizing the tank and related piping to verify there are no leaks and that components withstand the pressures they’ll experience when the water system is in use. Together, these tests demonstrate that the apparatus is sound both in its on-road operation and in the integrity of its water-handling system.
