If the requirements of NPFA 1901 are included in the apparatus bid specifications, which two tests must be performed by the manufacturer?

The road test and the hydrostatic test


When must road tests be conducted?

When construction of the apparatus is complete


When performing road tests, the apparatus should be:

fully loaded as it would be once in service.


In a road test, the apparatus must accelerate to ___ mph (km/h) from a standing start within 25 seconds.

35 mph (56 km/h)


In a road test, the apparatus must achieve a minimum top speed of ___ mph (km/h).

50 mph (80 km/h)


In a road test, the apparatus must come to a full stop from 20 mph (32 km/h) within ___ feet (m).

35 feet (10.7 m)


Pumps are tested hydrostatically at ___ psi (kPa) for three minutes.

250 psi (1 725 kPa)


Which of the following statements about hydrostatic tests is FALSE?

A. Discharge valves should be opened and capped.
B. Intake valves should be opened and capped.*
C. The tank fill line, tank-to-pump line, and by-pass line valves should be closed during this test.
D. The test pressure should be maintained for a minimum of three minutes without the failure of any component of the system.


Which of the following are some of the required pump certification tests for apparatus equipped with a 750 gpm (3 000 L/min) or larger fire pump?

A. Acceptance test, hydrostatic test, and road test
B. Pumping test, vacuum test, and priming device test*
C. Engine overhaul test, draining test, and external pressure relief valve test
D. Engine speed check, gauge and flowmeter test, and pressure control test


Apparatus equipped with a fire pump rated less than 750 gpm (3 000 L/min) are required to undergo the same certification tests, with the exception of:

A. the vacuum test.
B. the pumping test.
C. the priming device test.
D. the pumping engine overload test.*


Pumper service testing can use either a ___ or a static body of water.



When testing at a static source, the water must be at least ___ deep.

4 feet (1.2 m)


When testing at a static source, the strainer must be submerged at least ___ below the surface of the water.

2 feet (0.6 m)


When testing at a static source, the surface of the water may be no more than ___ below the centerline of the pump intake.

10 feet (3 m)


When testing at a static source, ___ of hard intake hose should be used for drafting during testing.

20 feet (6 m)


Air temperature should be between:

0ºF and 100ºF (-18ºC and 38ºC).


Water being used should be between:

35ºF and 90ºF (2ºC and 32ºC).


Barometric pressure should be at least ___ corrected to sea level.

29 inches Hg (98.2 kPa)


The driver/operator must lay out a sufficient number of hoses and nozzles to:

pump the rated capacity.


No hose smaller than ___ may be used, but larger hose may be used if available.

2½-inches (65 mm)


Hose must be tested to ensure that it is capable of withstanding the discharge pressure: A mark is scribed where the hose and couplings meet; if during the test, the scribe mark moves more than ___ away from the coupling, the test is stopped and the hose replaced and retested.

⅜ inch (9.5 mm)


All ___ should again be checked and any losses noted.

fluid levels


If the fire pump tests to less than ___ of its capabilities when it was new and underwent certification testing, two options are available.



If the apparatus does not test to desired results, the preferred action is to:

take the pump out of service and restore it to its designed capabilities.
