              3.8. Procedure

              3.8.1. "Cold start PEMS trip" means a trip with conditioning of the vehicle prior to the test as described in paragraph 8.3.2.

              3.8.2. "Hot start PEMS trip" means a trip without conditioning of the vehicle prior to the test as described in paragraph 8.3.2, but with a warm engine with coolant temperature above 70 °C. In the case that measuring the coolant temperature is not feasible, on request of the manufacturer and with approval of the approval authority, instead of using the coolant temperature, the engine oil temperature may be used.

              3.8.3. "Periodically regenerating system" means an exhaust emissions control device (e.g. catalytic converter, particulate trap) that requires a periodical regeneration.

              3.8.4. "Reagent" means any product other than fuel that is stored on-board the vehicle and is provided to the exhaust after-treatment system upon request of the emission control system.

              3.8.5. "Test start" means (Figure 4) whichever occurs first from:

                  (a) The first activation of the internal combustion engine;

                  (b) The first movement of the vehicle with speed greater than 1 km/h for OVC-HEVs and NOVC-HEVS.

              3.8.6. "Test end" means (Figure 5) that the vehicle has completed the trip and whichever occurs last from:

                  (a) The final deactivation of the internal combustion engine;

                  (b) The vehicle stops and the speed is lower than or equal to 1 km/h for OVC-HEVs and NOVC-HEVS finishing the test with deactivated internal combustion engine.

3.8.7. "Validation of PEMS" means the process of evaluating on a chassis dynamometer the correct installation and functionality within the given accuracy limits of a Portable Emissions Measurement System and exhaust mass flow rate measurements as obtained from one or multiple non-traceable exhaust mass flow meters or as calculated from sensors or ECU signals.
              4.                                Application for approval
              4.1. The application for approval of a vehicle type with regard to the requirements of this Regulation shall be submitted by the vehicle manufacturer or by their authorized representative, who is any natural or legal person who is duly appointed by the manufacturer to represent him before the approval authority and to act on his behalf in matters covered by this Regulation.

              4.1.1. The application referred to in paragraph 4.1. shall be drawn up in accordance with the model of the information document set out in Annex 1 to this Regulation.

              4.2. An appropriate number of vehicles representative of the vehicle type to be approved shall be submitted to the Technical Service responsible for the approval tests.

              4.3. Changes to the make of a system, component or separate technical unit that occur after a type approval shall not automatically invalidate a type approval, unless its original characteristics or technical
