Tank Testing Requirements
Static Tank Testing is a standard feature of the Fuel
Management System. SCALD is an option that can be
ordered when purchasing the console or after initial
purchase by using the part number TS-TT.
Test Types
This system is designed to perform two types of static tests
to comply with regulatory policies.
• 0.1 GPH Annual Leak Test — Detects a rate increase or
decrease of product in the tank, other than dispensing
(no testing during dispensing), at a rate greater than 0.1
gallons per hour.
• 0.2 GPH Monthly Leak Test — Detects a rate increase
or decrease of product in the tank, other than
dispensing (no testing during dispensing), at a rate
greater than 0.2 gallons per hour.
Ideal Testing Conditions
Tank and environmental conditions play an important role
in passing results. Consider the following items when
scheduling or manually forcing a static leak test:
Variable Explanation
Product Level
The level in the tank must submerge at least
the lowest RTD (temperature sensor) inside
the probe shaft.
Temperature
Stability
A tank with more product inside is likely to be
stable thermally and allow for higher quality
results.
Time of Day
This variable ties in with temperature stability.
Though not likely, product in the tank may
dramatically rise and fall in temperature from
dawn to afternoon and then from dusk to night.
Typically, thermal issues affect Aboveground
Storage Tanks more often than Underground
Storage Tanks.
Deliveries
A period of time is required to wait without a
delivery between the last delivery and testing.
The time to wait is 4 hr 9 min for a 0.2 GPH
and 5 hr 18 min for a 0.1 GPH after a delivery
(in accordance with third party testing). This
time will allow the product to settle. If the wait
time is not observed, then the test may abort
or fail.
Dispensing
If dispensing occurs during a test, that test will
be aborted.
Test Time
The test should be scheduled or manually
forced when the test will not exceed the
maximum leak test time. If the maximum time
is surpassed, an Incomplete result is likely
to occur. If scheduling or manually forcing a
test, take into account what the sites hours
of operation are to avoid a dispense during
testing. Doing this will prevent aborted and
incomplete tests.
How to Manually Start Static Tests
This procedure requires User level privileges.
1. Starting at the Home screen, open the Quick Jump
menu.
2. Select Tanks and then click on which tank to start
a test.
3. Press the Control button.
4. Press the Test Type and choose either Monthly or
Annual.
Static Test Results
Pass – A passing result ensures the integrity of the tank is
good.
Fail – Test failure will be indicated by a Warning light and/or
annunciator. Additionally, a report may print (if the console
is programmed to do so, see the TS-550 evo Programming
Guide p/n 000-2173)
Abort – The result has been stopped due to variations in
float level and/or product temperature that are outside of
the leak test threshold. This may be caused by:
• Dispensing
• Loss of Probe Signal
• Delivery
• Rapid Temperature Change
• Theft
• Product Lower than the lowest RTD
• Pump Started
Incomplete – When the test does not collect enough data
before the programmed time limit ends, the test will be
Incomplete. When it’s necessary to obtain valid results for
compliance reasons, start the test manually.
