  1 When a bi fuel vehicle is combined with a flex fuel vehicle, both test requirements are applicable.
  2 This provision is temporary, further requirements for biodiesel and hydrogen shall be proposed later on.
  3 For this test, fuel applicable to low ambient temperatures should be used. In the absence of a winter grade reference fuel specification, the applicable winter grade fuel for this test should be agreed between the Approval Authority and the manufacturer according to the existing market specifications. Development of a reference fuel for this application is underway.

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.and its sub-paragraphs.
              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/biomethane shall be tested in the Type I test for variation in the composition of LPG or NG/biomethane, as set out in Annex 12. Vehicles that can be fuelled either with petrol or LPG or NG/biomethane shall be tested on both the fuels, tests on LPG or NG/biomethane being performed for variation in the composition of LPG or NG/biomethane, 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
