What two tests are typically performed if the requirements of NFPA 1901 are in the apparatus bid specifications?

The correct answer reflects the testing protocols outlined in NFPA 1901, which pertains to the construction and design of fire apparatus. Road tests are critical in assessing how the fire apparatus performs under actual operating conditions, evaluating factors such as handling, braking, acceleration, and overall drivability. Hydrostatic tests, on the other hand, are essential for examining the integrity and performance of the fire pump and its associated systems. This test ensures that the components can withstand pressure levels that are higher than what they would typically encounter during service.

Combining these two types of tests—road and hydrostatic—provides a comprehensive evaluation of both the mobility and firefighting capabilities of the apparatus. The other options include tests that are important in various contexts but do not align with the specific requirements listed in NFPA 1901 for fire apparatus evaluation.
