| Certification |
Leak rate of 3.0 gph at 10 psi* 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 |
2.0 gph for leak
rate of 3.0 gph.
0.062 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. |
| Specification |
System tests
pressurized
flexible pipelines.
Tests are conducted at operating pressure.
System will not function with a mechanical line leak detector installed on
the pipeline. |
| Pipeline
Capacity |
Maximum of 49.6
gallons. |
| Waiting
Time |
None between
delivery and testing.
None between dispensing and testing. |
| Test
Period |
Response time is
1 to 6 minutes for leak rate of 3.0 gph.
Response time is 2 hours, 18 minutes to 5 hours for leak rate of 0.1
gph.
Test data are acquired and recorded by a permanently installed
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.
Pump shutdown, message display, and alarm activation if leak is declared. |
| Calibration |
System must be
checked annually and, if necessary, calibrated in accordance with
manufacturer's instructions. |
