        9.3.3.6. Remarks

         The following recursive formulae are useful for computing successive values of the test statistic:

        9.4. Vehicles powered by an electric power train only:

         As a general rule, measures to ensure the conformity of production with regard to electric energy consumption is checked on the basis of the description in the type approval certificate set out in Annex 4 to this Regulation.

        9.4.1. The holder of the approval shall, in particular:

        9.4.1.1. Ensure the existence of procedures for the effective control of production quality;

        9.4.1.2. Have access to the equipment necessary for checking conformity with each approved type;

        9.4.1.3. Ensure that the data concerning the test result are recorded and that the annexed documents are available during a period to be agreed with the administrative service;

        9.4.1.4. Analyse the results of each type of test so as to monitor and ensure the consistency of the characteristics of the product, taking into account the variations admissible in industrial manufacture;

        9.4.1.5. Make sure that for each type of vehicle tests prescribed in Annex 7 to this Regulation are carried out; notwithstanding the requirements of paragraph 2.3.1.6. of Annex 7, at the request of the manufacturer, the tests will be carried out on vehicles which have not travelled any distance;

        9.4.1.6. Make sure that any collections of samples or test pieces demonstrating non-conformity with the type test under consideration is followed by a subsequent sampling and a further test.  All necessary steps shall be taken to re-establish the conformity of production.

        9.4.2. The competent authorities issuing the approval may verify at any time the methods applied in each production unit.

        9.4.2.1. In every inspection,
