VI.A.(2).•
The stack sample rotometer is checked by running three tests at each flow rate used
during the test program. The flow rate is checked by running the rotometer in series
with one of the dry gas meters for 10 minutes with the rotometer at a constant setting.
The dry gas meter volume measured is then corrected to standard temperature and
pressure conditions. The flow rate determined is then used to calculate actual
sampled volumes.
VI.A.(3).•
The continuous analyzers are zeroed and spanned before each test with appropriate
gases. A mid-scale multi-component calibration gas is then analyzed (values are
recorded). At the conclusion of a test, the instruments are checked again with zero,
span and calibration gases (values are recorded only). The drift in each meter is then
calculated and must not exceed 5% of the scale used for the test.
At the conclusion of each unit test program, a three-point calibration check is made.
This calibration check must meet accuracy requirements of the applicable standards.
Consistent deviations between analyzer readings and calibration gas concentrations
are used to correct data before computer processing. Data is also corrected for inter-
ferences as prescribed by the instrument manufacturer's instructions.
VI.B.• TEST•METHOD•PROCEDURES•
VI.B.(1).•
Before and after each test, each sample train is tested for leaks. Leakage rates are
measured and must not exceed 0.02 CFM or 4% of the sampling rate. Leak checks
are performed checking the entire sampling train, not just the dry gas meters. Pre-
test and post-test leak checks are conducted with a vacuum of 10 inches of mercury.
Vacuum is monitored during each test and the highest vacuum reached is then used
for the post test vacuum value. If leakage limits are not met, the test run is rejected.
During, these tests the vacuum was typically less than 2 inches of mercury. Thus,
leakage rates reported are expected to be much higher than actual leakage during
the tests.
