Annex 5
  Type II Test

(Carbon monoxide emission test at idling speed)
              1. Introduction
                This annex describes the procedure for the Type II test defined in paragraph 5.3.2. of this Regulation.
              2. Conditions of measurement
              2.1. The fuel shall be the reference fuel, specifications for which are given in Annexes 10 and 10a to this Regulation.
              2.2. During the test, the environmental temperature shall be between 293 and 303 K (20 and 30 °C). The engine shall be warmed up until all temperatures of cooling and lubrication means and the pressure of lubrication means have reached equilibrium.
              2.2.1. Vehicles that are fuelled either with petrol or with LPG or NG/biomethane shall be tested with the reference fuel(s) used for the Type I Test.
              2.3. In the case of vehicles with manually-operated or semi-automatic-shift gearboxes, the test shall be carried out with the gear lever in the "neutral" position and with the clutch engaged.
              2.4. In the case of vehicles with automatic-shift gearboxes, the test shall be carried out with the gear selector in either the "neutral" or the "parking" position.
              2.5. Components for adjusting the idling speed
              2.5.1. Definition
               For the purposes of this Regulation, "components for adjusting the idling speed" means controls for changing the idling conditions of the engine which may be easily operated by a mechanic using only the tools described in paragraph 2.5.1.1. below. In particular, devices for calibrating fuel and air flows are not considered as adjustment components if their setting requires the removal of the set-stops, an operation which cannot normally be performed except by a professional mechanic.
              2.5.1.1. Tools which may be used to control components for adjusting the idling speed: screwdrivers (ordinary or cross-headed), spanners (ring, open-end or adjustable), pliers, Allen keys.
              2.5.2. Determination of measurement points
              2.5.2.1. A measurement at the setting in accordance with the conditions fixed by the manufacturer is performed first;
              2.5.2.2. For each adjustment component with a continuous variation, a sufficient number of characteristic positions shall be determined.
              2.5.2.3. The measurement of the carbon-monoxide content of exhaust gases shall be carried out for all the possible positions of the adjustment components, but for components with a continuous variation only the positions defined in paragraph 2.5.2.2. above shall be adopted.
              2.5.2.4. The Type II Test shall be considered satisfactory if one or both of the two following conditions is
