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, ethanol blends up through E100, biodiesel blends B6-B20 meeting ASTM D7467, biodiesel B100 meeting ASTM D6751*.
Other liquids with known coefficients of expansion and density may be tested after consultation with the manufacturer.
*NWGLDE Listings apply to leak detection functionality only and not material compatibility - see "Disclaimer".

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.
Total vertical rise of pipeline must not exceed 11 feet above leak detector.
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.
