E
T
– Total Particulate Emissions, g
ASTM E2515 equation (15)
Where:
C
s
= Concentration of particulate matter in tunnel gas, g/dscf
C
r
= Concentration particulate matter room air, g/dscf
Q
std
= Average dilution tunnel gas flow rate, dscf/hr
θ = Total time of test run, minutes
Sample calculation:
For Train 1
E
T
= ( 0.000102 -
0.000000 ) x 8469.6 x 361 /60
E
T
=
5.18 g
For Train 2
E
T
= ( 0.000105 -
0.000000 ) x 8469.6 x 361 /60
E
T
=
5.37 g
Average
E = 5.28 g
Total emission values shall not differ by more than 7.5% from the total average emissions
7.5% of the average = 0.40
Train 1 difference = 0.09
Train 2 difference = 0.09
