Certification
|
Leak
rate of 3.0 gph at 10 psi* with PD = 100% and PFA = 0%.
Leak rate of 0.2 gph at operating pressure with PD = 100%
and PFA = 0%.
Leak rate of 0.1 gph at 1.5 times operating pressure*
with PD = 100% and PFA = 0%.
*Since leak rate varies as a function of pressure, this
leak rate and pressure were certified using an equivalent
leak rate and pressure, in accordance with an acceptable
protocol.

|
Leak
Threshold
|
1.5
gph for leak rate of 3.0 gph.
0.1 gph for leak rate of 0.2 gph.
0.047 gph for leak rate of 0.1 gph.
A pipeline system should not be declared tight if the
test result indicates a loss that equals or exceeds this
threshold.
|
|
Applicability
|
Gasoline,
diesel, aviation fuel, fuel oil #4, methanol, ethanol,
gasoline blends with methanol and ethanol.
Other liquids may be tested after consultation with the
manufacturer.
|
|
Specification
|
System
tests pressurized fiberglass and steel pipelines.
Tests are conducted at operating pressure.
|
|
Pipeline
Capacity
|
Maximum
of 172 gallons for leak rate of 3.0 gph.
Maximum of 163 gallons for leak rates of 0.2 gph and 0.1
gph.
|
|
Waiting
Time
|
None
between delivery and testing.
None between dispensing and testing.
|
|
Test
Period
|
Response
time is 2 to 4 minutes for leak rate of 3.0 gph.
Response time is 2 minutes to 4 hours for leak rate of
0.2 gph.
Response time is 4 minutes to 4 hours, 45 minutes for
leak rate of 0.1 gph.
Test data are acquired and recorded by a microprocessor.
Calculations are automatically performed by the microprocessor.
|
|
System
Features
|
Permanent
installation on pipeline.
Automatic testing of pipeline.
Preset threshold.
Single test to determine if pipeline is leaking. Recording
and display of day, date, and time of conclusive test.
Pump shutdown, message display, and alarm activation if
leak is declared.
|
|
Calibration
|
Equipment
must be checked annually for capability of detecting a
line leak of 3.0 gph and, if necessary, calibrated in
accordance with manufacturer's instructions.
