|
Certification
|
Leak rate of 3.0
gph with PD = 100% and PFA = 0%.
|
|
Leak
Threshold
|
2.0 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.
Other liquids may be tested after consultation with the manufacturer.
|
|
Specification
|
System tests
pressurized flexible pipelines.
|
|
Pipeline
Capacity
|
Maximum of 49
gallons.
|
|
Waiting
Time
|
None between
delivery and testing.
None between dispensing and testing.
|
|
Test
Period
|
Response time is
less than 3 minutes.
|
|
System
Features
|
Permanent
installation on pipeline.
Automatic testing of pipeline. Preset threshold.
Single test to determine if pipeline is leaking.
Restricted flow to dispenser 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.
|
|
Comments
|
Enviroflex
pipeline with a bulk modulus* of 1,280 psi was used during this
evaluation.
To perform a valid test, time delays must be integrated into electronic
dispensing equipment or retrofitted in junction box. Without this delay,
there is no guarantee that a nozzle will be closed for sufficient time to
allow leak detector to perform pipeline test and provide uninterrupted
service.
