Mitchell's SIR Program Versions 2.6, 2.7
Statistical Inventory Reconciliation Test Method (Quantitative)
| Certification | Leak rate of 0.2 gph with PD = 99% and PFA = 1% (Version 2.7). Leak rate of 0.1 gph with PD = 99% and PFA = 1% (Version 2.6). |
|---|---|
| Leak Threshold | If the absolute value of the calculated leak rate (gain or loss) is less than the leak threshold and the minimum detectable leak rate is less than or equal to 0.2 gph (0.1 gph for the 0.1 gph test), the test result is "pass." If the absolute value of the calculated leak rate is greater than or equal to the leak threshold, the result is "fail." If the minimum detectable leak rate exceeds 0.2 gph (0.1 gph for the 0.1 gph test) and the absolute value of the calculated leak rate is less than the leak threshold, the test result is "inconclusive." |
| Applicability | Gasoline, diesel. Other more viscous liquids may be tested after consultation with the vendor. |
| Tank Capacity | Maximum of 45,000 gallons for single tanks. Maximum of 45,000 gallons cumulative capacity for manifolded tank systems with no more than 4 tanks in system. |
| Comments | 68% of data sets evaluated were from manifolded tank systems. Of 41 data sets submitted for evaluation, all were analyzed with conclusive results. Median monthly throughput of tanks evaluated was 22,370 gallons. Leak rates of 0.05, 0.1, and 0.2 gph were used in evaluation. Data sets used in this evaluation were supplied by evaluator. 100% of inventory data used in this evaluation were gauge stick readings. Gains (water ingress) are analyzed and evaluated on an individual basis. The same data sets were used for both the 1995 and 1997 evaluations. |
