PM shall be calculated using the following two equations:
PM=Vmix+ Vep× PeVep× dwhere exhaust gases are vented outside tunnel;
and:
PM=Vmix× PeVep× dwhere exhaust gases are returned to the tunnel;
where:
Vmixis the volume of diluted exhaust gases (see paragraph 2. of this Sub-Annex), under standard conditions;
Vepis the volume of diluted exhaust gas flowing through the particulate sampling filter under standard conditions;
Peis the mass of particulate matter collected by one or more sample filters, mg;
dis the distance driven corresponding to the test cycle, km.
