If NFPA 1901 is included in the bid specifications, what are the other two tests, other than the pump certifications tests, are to be performed?
- Road test
- Hydrostatic test
At a minimum, to meet the NFPA 1901 road test, what criteria must the apparatus be able to meet?
- accelerate to 35mph from a standing start within 25 seconds.
- Achieve a minimum top speed of 50 mph.
- Come to a full stop from 20mph within 35 feet.
- Apparatus parking break must conform to the specifications listed by the braking system manufacturer.
What is the hydrostatic test to determine?
Whether the pump and pump piping can withstand pressures normally encountered during fire fighting operations.
Pumps are tested hydrostatically at ___psi for _ minutes.
250 psi; 3
Test performed to make sure that the fire pump system operates in the manner for which it was designed after the pump and components are installed on the apparatus chassis.
Pump Certification Tests
Who conducts apparatus pump certification tests?
An independent testing organization such as Underwriters Laboratories
Where are the results the pump certification test results required to be placed?
Stamped into a plate that is affixed to the pump panel of the apparatus.
What pump certification tests does NFPA 1901 require for apparatus with 750 gpm pumps or larger?
- Pumping test
- Pumping Engine overload test
- Pressure control system test
- Priming device test
-Vacuum test
- Water tank-to-pump test
- Internal intake pressure relief valve test
According to NFPA 1901, apparatus with a pump capacity less than 750 gpm are require to do all the same tests as pumps larger, accept?
Pumping Engine Overload Test
The certification pumping test requires the pumped to be operated for _ hours, while the service pumping test requires only __ minutes of operation.
3 hours; 40 min
Test conducted to assure the purchaser that the apparatus meets bid specifications at the time of delivery.
Acceptance tests
An important acceptance issue arises when the jurisdiction purchasing the apparatus is located at an alititude in excess of ____ feet above sea level.
2,000 ft
The requirements for fire department service testing are contained in what NFPA standard?
NFPA 1911
What are the service tests contained in NFPA 1911 that a driver/operator should know to perform?
- Engine speed test
- Priming Device test
- Vacuum test
- Pumping test
- Overload test
- Pressure control test
- Gauge and flow meter test
- Tank-to-pump flow rate test
- Internal intake pressure relief valve test
When conducting the annual service tests from a static water source, what are the source requirements?
- Water at least 4ft deep
- Strainer must be submerged at least 2 feet.
- Surface of the water source can be no more than 10ft below the centerline of the pump intake
- 20' of hard intake hose should be used.
When conducting apparatus service tests, what should the air and water temperatures be for the test?
air temp of 0-100 degrees F
water temp of 35-90 degrees F
Altitude affects the pump's performance: lifting ability drops about 1 foot per ____ft increase in altitude.
1,000 ft
While pump testing, scribe a mark on the hose at the couplings, and regularly check the couplings to make sure the the hose is not pulling from them. How far must your scribe move from the coupling before you stop the test and replace that piece of hose?
3/8"
Pump service tests are to be conducted at what net pump discharge pressures?
150, 165(overload), 200, 250 psi
NFPA 1911 requires that all gauges must have been calibrated within how many days of testing?
60 days
This reads the flow directly in gallons per minute, may be used instead of a pitot gauge to determine the flow from the nozzles.
Flowmeter
The vacuum test is performed to check what?
- Priming Device
- Pump
- Hard intake hose for air leaks
In the vacuum test, if the apparatus is unable to reach __inches of mercury, the apparatus should be removed from service and repaired as soon as possible.
22 inches
The pumping test checks the overall condition of what?
Engine and pump
Any gauges that are off by more than what, should be re-calibrated, repaired, or replaced?
10 psi
The flow measured from the nozzle and the reading on a flowmeter should not be off by more than what percent?
10%
NFPA 1901 states that the piping should be sized so that pumpers with a capacity of 500gpm or less be capable of flowing ___gpm from their booster tank.
