Certification

Leak rate of 0.2 gph with PD = 99.94% and PFA = 1.006%.
Leak rate of 0.1 gph with PD = 97.20% and PFA = 2.76%.

Leak Threshold

0.1 gph for leak rate of 0.2 gph. 
0.05 gph for leak rate of 0.1 gph. 
A tank system should not be declared tight if the test result indicates a loss or gain that equals or exceeds this threshold.

Applicability

Gasoline, diesel, aviation fuel, fuel oil #4, biodiesel blends B6-B20 meeting ASTM D7467, biodiesel B100 meeting ASTM D6751.

Tank Capacity

Maximum of 30,000 gallons for leak rate of 0.2 gph.
Maximum of 20,000 gallons for leak rate of 0.1 gph.
Tank must be between 50 and 90% full.

Waiting Time

Minimum of 5 hours 20 minutes between delivery and testing for leak rate of 0.2 gph.
Minimum of 5 hours 20 minutes between delivery and testing for leak rate of 0.1 gph.
None between dispensing and testing.
There must be no delivery during waiting time.

Test Period

Length of the test is determined automatically based on quality of test data.
Average data collection time during evaluation was 5 hours 21 minutes for leak rate of 0.2 gph.
Average data collection time during evaluation was 4 hours 39 minutes for leak rate of 0.1 gph.
Test data is acquired and recorded by system's computer.
Leak rate is calculated from data determined to be valid by statistical analysis.
There must be no dispensing or delivery during the test.

Temperature

Probe contains 5 thermistors to monitor product temperature. 
At least one thermistor must be submerged in product during testing.

Water Sensor

Must be used to detect water ingress.
Minimum detectable water level in the tank is 0.208 inches.

Not evaluated using manifolded tank systems. Therefore, this certification is only applicable when there is a probe used in each tank and the siphon is broken during testing.
Tests only portion of tank containing product.
As product level is lowered, leak rate in a leaking tank decreases (due to lower head pressure). Consistent testing at low levels could allow a leak to remain undetected.
EPA leak detection regulations require testing of the portion of the tank system which routinely contains product.
EVO 200 can support up to 6 tanks.
EVO 400 can support up to 14 tanks.
