3.10 TANK LEAK/LEAK SUMMARY
Note: The Leak Summary Log contains a subset of the Tank Leak Log data including Start and End
Date, Tank ID, Product Type, Product Name, Slope, and Result. The latest passing test per tank for
all previous months are represented. If no passing test exists for a specific month, the latest fail is
recorded. Otherwise both Tank Leak and Leak Summary are functionally equal.
Start Date: The date and time the test was started
End Date: The date and time the test was completed
Tank ID: The Tank ID number, not Tank Hardware Channel number, assigned to the documented
tank. See Section 2.4.
Product Type: The Product Type assigned to the tank. See Section 2.4
Product Name: The name assigned to the tank. See Section 2.4
Net Volume Start: The total temperature-compensated of volume of liquid in the tank at the beginning
of the test
Net Volume End: The total temperature-compensated volume of liquid in the tank at the end of the
test
Start Temp: The average liquid temperature at the beginning of the test
End Temp: The average liquid temperature at the end of the test
Rate g/hour: The minimum detected loss that qualifies as a leak. See section 2.8
Slope: The actual average change in volume observed at the completion of the test
Result: Pass or Fail
Hr: The average cumulative change in volume at the end of each hour.
