FUEL DISPENSER FLOW RATE TEST PROCEDURE
(For 10 gpm / 37.9 Lpm maximum ow rate standard)
1. Observe a vehicle that is being fueled at the
dispenser's maximum ow rate. Start the stopwatch
when the dispenser indicates 1 gal / 3.8 L dispensed.
2. Carefully measure the time that it takes to dispense
exactly 2*** gal / 7.6 L of fuel.
3. If the time is greater than 11.8*** seconds there is
not a violation.
4. If the time is less than or equal to 11.8*** seconds,
repeat the test for another 2*** gal / 7.6 L into the
same vehicle (if possible). If the second test time
is also less than or equal to 11.8*** seconds, use a
calibrated fuel container to verify the accuracy of the
dispenser meter.
5. When the dispenser meter shows 5 gal / 18.9 L
and the volume dispensed is more than 6 cubic
inches over or under the 5 gal / 18.9 L mark on the
calibrated fuel container, note the amount in the
comment area of the fuels inspection form.
5a. If the volume in the calibrated fuel container
is 5 gal / 18.9 L or greater, record the two test
times and note as a violation.
5b. If the volume in the calibrated fuel container is
less than 5 gal / 18.9 L by more than 6 cubic
inches, conduct the test on another dispenser.
6. Dispose of the fuel following city, state, or federal
regulations.
