7.1.7.2.The type-approval authority, in cooperation with the manufacturer, must select a sample of vehicles with sufficient mileage whose use under normal conditions can be reasonably assured. The manufacturer must be consulted on the choice of the vehicles in the sample and be allowed to attend the confirmatory checks of the vehicles.
7.1.7.3.The manufacturer is authorized, under the supervision of the type-approval authority, to carry out checks, even of a destructive nature, on those vehicles with emission levels in excess of the limit values with a view to establishing possible causes of deterioration which cannot be attributed to the manufacturer himself (e. g. use of leaded petrol before the test date). Where the results of the checks confirm such causes, those test results are excluded from the conformity check.
7.1.7.4.Where the type-approval authority is not satisfied with the results of the tests in accordance with the criteria defined in Appendix 4, the remedial measures referred to in Article 11 (2) and in Annex X to Directive 70/156/EEC are extended to vehicles in service belonging to the same vehicle type which are likely to be affected with the same defects in accordance with section 6 of Appendix 3.

The plan of remedial measures presented by the manufacturer must be approved by the type-approval authority. The manufacturer is responsible for the execution of the remedial plan as approved.

The type-approval authority must notify its decision to all Member States within 30 days. The Member States may require the same plan of remedial measures be applied to all vehicles of the same type registered in their territory.

7.1.7.5.If a Member State has established that a vehicle type does not conform to the applicable requirements of Appendix 3 to this Annex, it must notify without delay the Member State which granted the original type-approval in accordance with the requirements of Article 11 (3) of Directive 70/156/EEC.

3.2.The OBD system shall be checked for proper functioning. Any malfunction indications in the OBD memory must be recorded and the requisite repairs must be carried out. If the OBD malfunction indicator registers a malfunction during a preconditioning cycle, the fault may be identified and repaired. The test may be re-run and the results of that repaired vehicle used.
3.3.The ignition system must be checked and defective components replaced, for example spark plugs, cables, etc.
3.4.The compression must be checked. If the result is unsatisfactory the vehicle is rejected.
3.5.The engine parameters must be checked to the manufacturer's specifications and adjusted if necessary.
3.6.If the vehicle is within 800 km of a scheduled maintenance service, that service must be performed according to the manufacturer's instructions. Regardless of odometer reading, the oil and air filter may be changed at the request of the manufacturer.
3.7.Upon acceptance of the vehicle, the fuel must be replaced with appropriate emission test reference fuel, unless the manufacturer accepts the use of market fuel.
4.IN-SERVICE TESTING
4.1.When a check on vehicles is deemed necessary, emission tests in accordance with Annex III to this Directive are performed on pre-conditioned vehicles selected in accordance with the requirements of sections 2 and 3 of this Appendix.
4.2.Vehicles equipped with an OBD system may be checked for proper in-service functionality of the malfunction indication, etc., in relation to levels of emissions (e. g. the malfunction indication limits defined in Annex XI to this Directive) for the type-approved specifications.
4.3.The OBD system may be checked, for example, for levels of emissions above the applicable limit values with no malfunction indication, systematic erroneous activation of the malfunction indication and identified faulty or deteriorated components in the OBD system.
4.4.If a component or system operates in a manner not covered by the particulars in the type-approval certificate and/or information package for such vehicle types and such deviation has not been authorized under Article 5 (3) or (4) of Directive 70/156/EEC, with no malfunction indication by the OBD, the component or system must not be replaced prior to emission testing, unless it is determined that the component or system has been tampered with or abused in such a manner that the OBD does not detect the resulting malfunction.
5.EVALUATION OF RESULTS
5.1.The test results are submitted to the evaluation procedure in accordance with Appendix 4 to this Annex.
5.2.Test results must not be multiplied by deterioration factors.
6.PLAN OF REMEDIAL MEASURES
6.1.When the type-approval authority is certain that a vehicle type is not in conformity with the requirements of these provisions, it must request the manufacturer to submit a plan of remedial measures to remedy the non-compliance.
6.2.The plan of remedial measures must be filed with the type-approval authority not later than 60 working days from the date of the notification referred to in section 6.1.

6.5.11.Where the plan of remedial measures includes a recall, a description of the method for recording the repair must be submitted to the type-approval authority. If a label is used, an example of it must be submitted.
6.6.The manufacturer may be required to conduct reasonably designed and necessary tests on components and vehicles incorporating a proposed change, repair, or modification to demonstrate the effectiveness of the change, repair, or modification.
6.7.The manufacturer is responsible for keeping a record of every vehicle recalled and repaired and the workshop which performed the repair. The type-approval authority must have access to the record on request for a period of 5 years from the implementation of the plan of remedial measures.
6.8.The repair and/or modification or addition of new equipment shall be recorded in a certificate supplied by the manufacturer to the vehicle owner.
Appendix 4(7) STATISTICAL PROCEDURE FOR IN-SERVICE CONFORMITY TESTING
1.This Appendix describes the procedure to be used to verify the in-service conformity requirements for the type I test.
2.Two different procedures are to be followed:
1.

One dealing with vehicles identified in the sample, due to an emission-related defect, causing outliers in the results (section 3).

2.

The other dealing with the total sample (section 4).

3.PROCEDURE TO BE FOLLOWED WITH OUTLYING EMITTERS IN THE SAMPLE.
3.1.A vehicle is said to be an outlying emitter, when for any regulated component the limit value as shown in section 5.3.1.4 of Annex I is exceeded significantly.
3.2.With a minimum sample size of 3, and a maximum sample size as determined by the procedure of paragraph 4, the sample is scanned for the occurrence of outlying emitters.
3.3.When an outlying emitter is found, the cause of the excess emission must be determined.
3.4.When more than one vehicle is found to be an outlying emitter, due to the same cause, the sample is regarded as having failed.
3.5.When only one outlying emitter has been found, or when more than one outlying emitter is found, but due to different causes, the sample is increased by one vehicle, unless the maximum sample size has already been reached.
3.5.1.When in the increased sample more than one vehicle is found to be an outlying emitter, due to the same cause, the sample is regarded as having failed.
3.5.2.When in the maximum sample size not more than one outlying emitter is found, where the excess emission is due to the same cause, the sample is regarded as having passed with regard to the requirements of section 3 of this Appendix.
3.6.Whenever a sample is increased due to the requirements of 3.5, the statistical procedure of paragraph 4 is applied to the increased sample.
4.PROCEDURE TO BE FOLLOWED WITHOUT SEPARATE EVALUATION OF OUTLYING EMITTERS IN THE SAMPLE.
4.1.With a minimum sample size of three the sampling procedure is set so that the probability of a batch passing a test with 40 % of the production defective is 0,95 (producer's risk = 5 %) while the probability of a batch being accepted with 75 % of the production defective is 0,15 (consumer's risk = 15 %).
4.2.For each of the pollutants given in section 6.2.1 of Annex I, the following procedure is used (see Figure 1/7).

Where

L

=

the limit value for the pollutant,

Xi

=

the value of the measurement for the i-th vehicle of the sample,

n

=

the current sample number.

4.3.The test statistic quantifying the number of non-conforming vehicles, i. e. xi > L, is computed for the sample.
4.4.Then:

In the following table the pass and fail decision numbers are computed in accordance with the International Standard ISO 8422:1991.

5.A sample is regarded as having passed the test when it has passed both the requirements of sections 3 and 4 of this Appendix.

The Lambda value must be calculated using the simplified Brettschneider equation as follows:

Where:

[ ]

=

Concentration in % vol.

K1

=

Conversion factor for NDIR measurement to FID measurement (provided by manufacturer of measurement equipment)

Hcv

=

Atomic ratio of hydrogen to carbon [1,7261]

Ocv

=

Atomic ratio of oxygen to carbon [0,0175].
