STATISTICAL INVENTORY
RECONCILIATION TEST METHOD (QUANTITATIVE)
| Certification |
Leak rate of 0.2 gph with PD > 99.9 % and PFA < 0.1% (Version 2).
Leak rate of 0.1 gph with PD = 96.5% and PFA = 3.5% (Version 1). |
| Leak
Threshold |
0.1 gph for leak rate of 0.2 gph (Version 2).
0.05 gph for leak rate of 0.1 gph (Version 1).
A tank system should not be declared tight if the test result indicates a loss or gain that equals or exceeds the threshold level of the version selected. |
| Applicability |
Gasoline, diesel. |
| Tank
Capacity |
