Correction of Volume to Standard Conditions. The diluted exhaust-gas volume is corrected by means of the following formula: ⎛ PB − P1 ⎞ ⎜ ⎟ Vmix = V ⋅K1 ⋅⎜ ⎟ ⎝ Tp ⎠ (1) where: (2) PB = barometric pressure in the test room in kPa, P1 = vacuum at the inlet to the positive displacement pump in kPa relative to the ambient barometric pressure, Tp = average temperature of the diluted exhaust gas entering the positive displacement pump during the test (K).
