United Kingdom
The particulate mass m PM,c [g] may be background corrected by means of equation (7-50):
| (7-50) |
Where:
m f m sep m sd m b m ed D
particulate mass sampled over the cycle [mg]
mass of diluted exhaust gas passing the particulate collection filters [kg]
mass of dilution air sampled by background particulate sampler [kg]
mass of collected background particulates of dilution air [mg]
mass of diluted exhaust gas over the cycle [kg]
dilution factor [see equation (7-28) of point 2.2.2.2] [-]
