Watson SIRAS Software System Versions 2.0, 2.8.3
Statistical Inventory Reconciliation Test Method (Quantitative)
| Certification | Leak rate of 0.2 gph with PD = 99.999% and PFA = 0.01% Leak rate of 0.1 gph with PD = 99.3% and PFA = 0.7% |
|---|---|
| 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 30,000 gallons. Size limits using an acceptable protocol for manifolded tank systems have not been determined. |
| Data Requirement | Minimum of 30 days of usable product level and flow through data. |
| System Features | Backup technical support for the end user was part of the service feature of these SIR versions and was provided through contract with Watson Systems, Inc. Since these SIR versions are now owned by USTMAN Technologies, Inc., information, assistance, and technical support for these versions are at their discretion. |
| Comments | Not evaluated for in-house use that is independent of vendor participation. Not evaluated for manifolded tank systems using an acceptable protocol. 27% of data sets evaluated were from manifolded tank systems. Of 56 data sets submitted for evaluation, 6 were not analyzed due to unusable data. Median monthly throughput for tanks evaluated was 73,518 gallons. Leak rates ranging from 0.0458 to 0.2500 gph were used in evaluation. Data sets evaluated were supplied by evaluator. |
