ANNEX I

Table 1 Euro 5 emission limits Key: PI = Positive ignition, CI = Compression ignition A number standard is to be defined as soon as possible and at the latest upon entry into force of Euro 6. Positive ignition particulate mass standards apply only to vehicles with direct injection engines. Reference mass (RM) (kg) Limit values Mass of carbon monoxide (CO) Mass of total hydrocarbons (THC) Mass of non-methane hydrocarbons (NMHC) Mass of oxides of nitrogen (NO_(x)) Combined mass of total hydrocarbons and oxides of nitrogen (THC + NO_(x)) Mass of particulate matter (PM) Number of particles (P) L_(1) (mg/km) L_(2) (mg/km) L_(3) (mg/km) L_(4) (mg/km) L_(2) + L_(4) (mg/km) L_(5) (mg/km) L_(6) (#/km) Category Class PI CI PI CI PI CI PI CI PI CI PI CI PI CI M — All 1000 500 100 — 68 — 60 180 — 230 5,0 5,0 N_(1) I RM ≤ 1305 1000 500 100 — 68 — 60 180 — 230 5,0 5,0 II 1305 < RM ≤ 1760 1810 630 130 — 90 — 75 235 — 295 5,0 5,0 III 1760 < RM 2270 740 160 — 108 — 82 280 — 350 5,0 5,0 N_(2) 2270 740 160 — 108 — 82 280 — 350 5,0 5,0 Table 2 Euro 6 emission limits Key: PI = Positive ignition, CI = Compression ignition A number standard is to be defined for this stage.
