Performance Testing
Note that the NFPA standards require a 10% reserve in pressure at the capacity
run when the apparatus is delivered. Also see NFPA 1901 Standard for testing
procedures.
1. Test the relief valve (per NFPA 1901 standards):
❑ Set the relief valve flow rate capacity at 150 PSI (10 BAR).
❑ SLOWLY close the discharge valves. The rise in pressure shall not
exceed 30 PSI (2 BAR), or approximately 180 PSI (12 BAR) operating
pressure.
❑ SLOWLY open the discharge valves to re-establish the original pressure
(150 PSI).
2. Perform Steps 2 and 3 of the post operation maintenance procedures - see
heading “Post Operation Procedures” on page 44.
3. Run the standard pump test in accordance with NFPA 1901 standards to
check pump performance.
Run the engine for 20 to 30 minutes to stabilize the engine temperature.
Then run the pump for:
❑ Two (2) hours at FULL capacity and at 150 PSI (10 BAR)
❑ Thirty (30) minutes at 70% capacity and at 200 PSI (14 BAR)
❑ Thirty (30) minutes at 50% capacity and at 250 PSI (17 BAR)
❑ Additionally, an engine overload test is required which consists of pump-
ing at FULL capacity and at 165 PSI (11 BAR) for ten (10) minutes.
4. If the apparatus does not reach performance levels, proceed to Section 5
“Troubleshooting” on page 59.
5. Compare results of this test to those when the apparatus was first
delivered. If the apparatus performance has dropped appreciably, com-
pared to its original performance, it needs to be serviced.
Note: Apparatus test results should be on file with the delivery documents. If not,
they may be obtained from the apparatus manufacturer or from the original certifying
authority.
