Maximum acceptable value for Initial DO minus Final DO in the dilution-blank test. This
criterion is checked only for Dilution Blank samples. The default value is 0.2 mg/l.
Maximum Initial Dissolved Oxygen (mg/l)
The maximum acceptable value for the Initial DO. This is checked for all tests. The default value
is 9.7 mg/l.
Minimum Final Dissolved Oxygen (mg/l)
The minimum acceptable value for the Final DO This is checked for all tests. The default value
is 1.0 mg/l.
Minimum (Initial DO - Final DO) (mg/l)
The minimum acceptable value for oxygen depletion. This is checked for all tests except the
Dilution Blank tests. The default value is 2.0 mg/l.
Remove Depletion caused by Seed
For the Minimum (Initial DO – Final DO) should the Depletion caused by Seed be removed
before the criteria is applied. With the field checked, if the depletion is 2.2 mg/l but 0.4 mg/l of
the depletion was caused by seed, the bottle will be marked since the depletion due to the sample
is 1.8 mg/l (2.2 – 0.4).
Minimum Oxygen Depletion % for Seed Tests (%)
The minimum percentage depletion for Seed tests. Percentage depletion is defined as Final DO /
Initial DO * 100. Checked for samples that are used as Seed only. This criterion is not checked
if left blank. If used, a typical value is 40.
Maximum Oxygen Depletion % for Seed Tests (%)
The maximum percentage depletion for Seed tests. Percentage depletion is defined as Final DO /
Initial DO * 100. Checked for samples that are used as Seed only. This criterion is not checked
if left blank. If used, a typical value is 60.
Use Seed that was closest to 50% depletion
For the entire Seed sample find the bottle (dilution) that is closest to 50% depletion. Mark all
other bottles in the sample.
Minimum Seed Correction Factor (mg/l)
The minimum acceptable value of the seed correction factor. The value checked is not the seed
correction per ml. It is the actual seed correction used in BOD calculations derived by
multiplying the seed correction per milliliter by the amount of seed used in the test. This is
checked for any test using seed. The default value is 0.6 mg/l.
Maximum Seed Correction Factor (mg/l)
The maximum value of the seed correction factor. This is checked for any test using seed. The
default value is 1.0 mg/l.
Minimum Standard Test BOD (mg/l)
The minimum acceptable value of BOD for tests with the sample name Standard. The default
value is 163 mg/l (or, 200 minus 37).
