EPA TEST METHODS
A SUMMARY OF THE EPA CONDITIONAL TEST METHOD CTM-030
REQUIREMENTS FOR CO, NO
X
AND O
2
EMISSIONS
This method is applicable for the measurement of oxygen, carbon monoxide and
oxides of nitrogen (NO
X
) emissions from sources using gaseous and liquid fuels.
NO
X
is the sum of NO (nitric oxide) and NO
2
(nitrogen dioxide) concentrations. If
the NO
2
concentration during measurement is known to be less than 10% of NO
X
,
you may estimate it and add it to NO, if it is more than 10%, then you must also
measure the NO
2
concentration.
If an NO
2
measurement is required, then a chilled condenser must be used and the
transport line to the analyzer must not get wet and scrub the NO
2
gas. “The sample
line must be designed to prevent condensation”.
Unlike Method 7E, a single calibration span gas is required for each CO, NO and
NO
2
calibrations.
The sample flow rate must be monitored before and after each test and not vary by
more than 10%, or cause the readings to change by more than 3%.
During a measurement cycle the temperature of the sensors must be monitored and
must not change by more than 10 °F.
Unlike Method 7E, clean air may be used to zero the analyzer.
The accuracy requirements for CTM-030 are based on the calibration span gas that
is used:
1. Zero calibration error:
< 3% of span gas for CO, NO, NO
2
< 0.3% for O
2
2. Span calibration error:
< 5% of span gas for all sensors
3. Interference response:
< 5% of span gas for all sensors
4. Repeatability check:
< 3% of span gas after four measurement cycles
