             and, where applicable, OBD test.

           5.3.  Description of tests

           5.3.1.  Type I test (Simulating the average exhaust emissions after a cold start).

           5.3.1.1. Figure 1 illustrates the routes for Type I test. This test shall be carried out on all vehicles referred to in paragraph 1., having a maximum mass not exceeding 3.5 tonnes.

           5.3.1.2. The vehicle is placed on a chassis dynamometer equipped with a means of load and inertia simulation.

           5.3.1.2.1. A test lasting a total of 19 minutes and 40 seconds, made up of two parts, One and Two, is performed without interruption. An unsampled period of not more than 20 seconds may, with the agreement of the manufacturer, be introduced between the end of Part One and the beginning of Part Two in order to facilitate adjustment of the test equipment.

           5.3.1.2.1.1. Vehicles that are fuelled with LPG or NG shall be tested in the Type I test for variation in the composition of LPG or NG, as set out in Annex 12.  Vehicles that can be fuelled either with petrol or LPG or NG shall be tested on both the fuels, tests on LPG or NG being performed for variation in the composition of LPG or NG, as set out in Annex 12.

           5.3.1.2.1.2. Notwithstanding the requirement of paragraph 5.3.1.2.1.1., vehicles that can be fuelled with either petrol or a gaseous fuel, but where the petrol system is fitted for emergency purposes or starting only and which the petrol tank cannot contain more than 15 litres of petrol will be regarded for the test Type I as vehicles that can only run on a gaseous fuel.

           5.3.1.2.2. Part One of the test is made up of four elementary urban cycles. Each elementary urban cycle comprises fifteen phases (idling, acceleration, steady speed, deceleration, etc.).

           5.3.1.2.3. Part Two of the test is made up of one extra-urban cycle.
           The extra-urban cycle comprises 13 phases (idling, acceleration, steady speed, deceleration, etc.).
