[F27.1.3.1.2.] If the authority is satisfied with the production standard deviation given by the manufacturer in accordance with Annex X to Directive 70/156/EEC, the tests are carried out according to Appendix 1 of this Annex. U.K.

If the authority is not satisfied with the production standard deviation given by the manufacturer in accordance with Annex X to Directive 70/156/EEC, the tests are carried out according to Appendix 2 of this Annex.

[F27.1.3.1.3.] The production of a series is deemed to conform or not to conform on the basis of a sampling test of the vehicles once a pass decision is reached for all the pollutants or a fail decision is reached for one pollutant, according to the test criteria applied in the appropriate appendix. U.K.

When a pass decision has been reached for one pollutant, that decision will not be changed by any additional tests carried out to reach a decision for the other pollutants.

If no pass decision is reached for all the pollutants and no fail decision is reached for one pollutant, a test is carried out on another vehicle (see Figure I/7).

[F27.1.3.2.] Notwithstanding the requirements of Section 3.1.1 of Annex III, the tests will be carried out on vehicles coming straight off the production line. U.K.
[F27.1.3.2.1.] However, at the request of the manufacturer, the tests may be carried out on vehicles which have completed: U.K.
  • a maximum of 3 000  km for vehicles equipped with a positive ignition engine,

  • a maximum of 15 000  km for vehicles equipped with a compression ignition engine,

In both these cases, the running-in procedure will be conducted by the manufacturer, who must undertake not to make any adjustments to these vehicles.

[F27.1.3.2.2.] If the manufacturer wishes to run in the vehicles, ( x km, where x ≤  3 000  km for vehicles equipped with a positive ignition engine and x ≤  15 000  km for vehicles equipped with a compression ignition engine), the procedure will be as follows: U.K.

  • the evolution coefficient of the emissions between zero and x km will be calculated for each of the pollutants:

    This may be less than 1,

  • the other vehicles will not be run in, but their zero km emissions will be multiplied by the evolution coefficient.

    In this case, the values to be taken will be:

    • the values at x km for the first vehicle,

    • the values at zero km multiplied by the evolution coefficient for the other vehicles.

[F27.1.3.2.3.] All these tests may be conducted with commercial fuel. However, at the manufacturer's request, the reference fuels described in Annex VIII may be used. U.K.

7.1.6.1. When the approval authority determines that the quality of production seems unsatisfactory a vehicle is randomly taken from the series and subjected to the tests described in Annex XI, Appendix 1. U.K.
7.1.6.2. The production is deemed to conform if this vehicle meets the requirements of the tests described in Annex XI, Appendix 1. U.K.
7.1.6.3. If the vehicle taken from the series does not satisfy the requirements of section 7.1.6.1 a further random sample of four vehicles must be taken from the series and subjected to the tests described in Annex XI, Appendix 1. The tests may be carried out on vehicles which have been run in for no more than 15 000  km. U.K.
7.1.6.4. The production is deemed to conform if at least 3 vehicles meet the requirements of the tests described in Annex XI, Appendix 1.] U.K.
[F5 [F37.1.7. On the basis of the audit referred to in section 7.1.1, the type-approval authority must either: U.K.
  • decide that the in-service conformity of a vehicle type or a vehicle in-service family is satisfactory and not take any further action,

  • decide that the data provided by the manufacturer is insufficient to reach a decision and request additional information or test data from the manufacturer, or

  • decide that the in-service conformity of a vehicle type, or vehicle type(s) that is/are part of an in-service family, is unsatisfactory and proceed to have such vehicle type(s) tested in accordance with Appendix 3 to this Annex.

In the case that the manufacturer has been permitted to not carry out an audit for a particular vehicle type in accordance with section 7.1.2, the type-approval authority may proceed to have such vehicle types tested in accordance with Appendix 3 to this Annex.]

7.1.7.1. Where type I tests are considered necessary to check the conformity of emission control devices with the requirements for their performance while in service, such tests must be carried out using a test procedure meeting the statistical criteria defined in Appendix 4 to this Annex. U.K.
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. U.K.
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. U.K.
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. U.K.

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. U.K.

Then, subject to the provision of Article 11(6) of Directive 70/156/EEC, the competent authority of the Member State which granted the original type-approval shall inform the manufacturer that a vehicle type fails to satisfy the requirements of these provisions and that certain measures are expected of the manufacturer. The manufacturer shall submit to the authority, within two months after this notification, a plan of measures to overcome the defects, the substance of which should correspond to the requirements of sections 6.1 to 6.8 of Appendix 3. The competent authority which granted the original type-approval shall, within two months, consult the manufacturer in order to secure agreement on a plan of measures and on carrying out the plan. If the competent authority which granted the original type-approval establishes that no agreement can be reached, the procedure pursuant to Article 11(3) and (4) of Directive 70/156/EEC shall be initiated.] ]

[F5Appendix 3 IN-SERVICE CONFORMITY CHECK

1. INTRODUCTION U.K.

This Appendix sets out the criteria referred to in section 7.1.7 of this Annex regarding the selection of vehicles for testing and the procedures for the in-service conformity control.

2. SELECTION CRITERIA U.K.

The criteria for acceptance of a selected vehicle are defined in sections 2.1 to 2.8 of this Appendix. Information is collected by vehicle examination and an interview with the owner/driver.

2.1. The vehicle must belong to a vehicle type that is type-approved under this Directive and covered by a certificate of conformity in accordance with Directive 70/156/EEC. It must be registered and used in the European Community. U.K.
2.2. The vehicle must have been in service for at least 15 000  km or 6 months, whichever is the later, and for no more than 80 000  km or 5 years, whichever is the sooner. U.K.
2.3. There must be a maintenance record to show that the vehicle has been properly maintained, e. g. has been serviced in accordance with the manufacturer's recommendations. U.K.
2.4. The vehicle must exhibit no indications of abuse (e. g. racing, overloading, misfuelling, or other misuse), or other factors (e. g. tampering) that could affect emission performance. In the case of vehicles fitted with an OBD system, the fault code and mileage information stored in the computer are taken into account. A vehicle must not be selected for testing if the information stored in the computer shows that the vehicle has operated after a fault code was stored and a relatively prompt repair was not carried out. U.K.
2.5. There must have been no unauthorized major repair to the engine or major repair of the vehicle. U.K.
[F32.6. The lead content and sulphur content of a fuel sample from the vehicle tank must meet the applicable standards laid down in Directive 98/70/EC (5) and there must be no evidence of mis-fuelling. Checks may be done in the tailpipe etc.] U.K.
2.7. There must be no indication of any problem that might jeopardize the safety of laboratory personnel. U.K.
2.8. All anti-pollution system components on the vehicle must be in conformity with the applicable type-approval. U.K.

3. DIAGNOSIS AND MAINTENANCE U.K.

Diagnosis and any normal maintenance necessary must be performed on vehicles accepted for testing, prior to measuring exhaust emissions, in accordance with the procedure laid down in section 3.1 to 3.7.

3.1. The following checks must be carried out: checks on air filter, all drive belts, all fluid levels, radiator cap, all vacuum hoses and electrical wiring related to the antipollution system for integrity; checks on ignition, fuel metering and anti-pollution device components for maladjustments and/or tampering. All discrepancies must be recorded. U.K.
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. U.K.
3.3. The ignition system must be checked and defective components replaced, for example spark plugs, cables, etc. U.K.
3.4. The compression must be checked. If the result is unsatisfactory the vehicle is rejected. U.K.
3.5. The engine parameters must be checked to the manufacturer's specifications and adjusted if necessary. U.K.
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. U.K.
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. U.K.

4. IN-SERVICE TESTING U.K.

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. U.K.
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. U.K.
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. U.K.
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. U.K.

5. EVALUATION OF RESULTS U.K.

5.1. The test results are submitted to the evaluation procedure in accordance with Appendix 4 to this Annex. U.K.
5.2. Test results must not be multiplied by deterioration factors. U.K.

6. PLAN OF REMEDIAL MEASURES U.K.

[F36.1. When more than one vehicle is found to be an outlying emitter that either, U.K.
  • meets the conditions of section 3.2.3 of Appendix 4 and where both the type-approval authority and the manufacturer agree that the excess emission is due to the same cause, or

Appendix 4 (6) 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. U.K.

2. Two different procedures are to be followed: U.K.

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).

[F33. PROCEDURE TO BE FOLLOWED WITH OUTLYING EMITTERS IN THE SAMPLE (7) U.K.

3.1. With a minimum sample size of three and a maximum sample size as determined by the procedure of paragraph 4, a vehicle is taken at random from the sample and the emissions of the regulated pollutants are measured to determine if it is an outlying emitter. U.K.
3.2. A vehicle is said to be an outlying emitter when the conditions given in either section 3.2.1 or section 3.2.2 are met. U.K.
3.2.1. In the case of a vehicle that has been type-approved according to the limit values given in row A of the table in section 5.3.1.4 of Annex I, an outlying emitter is a vehicle where the applicable limit value for any regulated pollutant is exceeded by a factor of 1,2. U.K.
3.2.2. In the case of a vehicle that has been type-approved according to the limit values given in row B of the table in section 5.3.1.4 of Annex I, an outlying emitter is a vehicle where the applicable limit value for any regulated pollutant is exceeded by a factor of 1,5. U.K.
3.2.3. In the specific case of a vehicle with a measured emission for any regulated pollutant within the intermediate zone ’(8) . U.K.
3.2.3.1. If the vehicle meets the conditions of this section, the cause of the excess emission must be determined and another vehicle is then taken at random from the sample. U.K.
3.2.3.2. Where more than one vehicle meets the condition of this section, the type-approval authority and the manufacturer must determine if the excess emission from both vehicles is due to the same cause or not. U.K.
3.2.3.2.1. If the type-approval authority and the manufacturer both agree that the excess emission is due to the same cause, the sample is regarded as having failed and the plan of remedial measures outlined in section 6 of Appendix 3 applies. U.K.
3.2.3.2.2. If the type-approval authority and the manufacturer can not agree on either the cause of the excess emission from an individual vehicle or whether the causes for more than one vehicle are the same, another vehicle is taken at random from the sample, unless the maximum sample size has already been reached. U.K.
3.2.3.3. When only one vehicle meeting the conditions of this section has been found, or when more than one vehicle has been found and the type-approval authority and the manufacturer agree it is due to different causes, another vehicle is taken at random from the sample, unless the maximum sample size has already been reached. U.K.
3.2.3.4. If the maximum sample size is reached and not more than one vehicle meeting the requirements of this section has been 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. U.K.
3.2.3.5. If, at any time, the initial sample has been exhausted, another vehicle is added to the initial sample and that vehicle is taken. U.K.
3.2.3.6. Whenever another vehicle is taken from the sample, the statistical procedure of paragraph 4 of this Appendix is applied to the increased sample. U.K.
3.2.4. In the specific case of a vehicle with a measured emission for any regulated pollutant within the failure zone ’(9) . U.K.
3.2.4.1. If the vehicle meets the conditions of this section, the type-approval authority shall determine the cause of the excess emission and another vehicle is then taken at random from the sample. U.K.
3.2.4.2. Where more than one vehicle meets the condition of this section, and the type-approval authority determines that the excess emission is due to the same cause, the manufacturer shall be informed that the sample is regarded as having failed, together with the reasons for that decision, and the plan of remedial measures outlined in section 6 of Appendix 3 applies. U.K.
3.2.4.3. When only one vehicle meeting the conditions of this section has been found, or when more than one vehicle has been found and the type-approval authority has determined that it is due to different causes, another vehicle is taken at random from the sample, unless the maximum sample size has already been reached. U.K.
3.2.4.4. If the maximum sample size is reached and not more than one vehicle meeting the requirements of this section has been 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. U.K.
3.2.4.5. If, at any time, the initial sample has been exhausted, another vehicle is added to the initial sample and that vehicle is taken. U.K.
3.2.4.6. Whenever another vehicle is taken from the sample, the statistical procedure of paragraph 4 of this Appendix is applied to the increased sample. U.K.
3.2.5. Whenever a vehicle is not found to be an outlying emitter, another vehicle is taken at random from the sample.] U.K.

4. PROCEDURE TO BE FOLLOWED WITHOUT SEPARATE EVALUATION OF OUTLYING EMITTERS IN THE SAMPLE. U.K.

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 %). U.K.
4.2. For each of the pollutants given in [X1section 5.3.1.4 of Annex I,] the following procedure is used [F3(see Figure I.9)] . U.K.

Where

L

=

the limit value for the pollutant,

X i

=

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. x i > L, is computed for the sample. U.K.
4.4. Then: U.K.
  • if the test statistic does not exceed the pass decision number for the sample size given in the following table, a pass decision is reached for the pollutant,

  • if the test statistic equals or exceeds the fail decision number for the sample size given in the following table, a fail decision is reached for the pollutant,

  • otherwise, an additional vehicle is tested and the procedure is applied to the sample with one extra unit.

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. U.K.

The provisions laid down in Appendix 4 must be re-examined and completed without delay in accordance with the procedure laid down in Article 13 of Directive 70/156/EEC.

(7)

[F3On the basis of actual in-service data to be supplied before 31 December 2003 by the Member States, the requirements of this section may be reviewed and consider (a) whether the definition of outlying emitter needs to be revised with respect to vehicles that have been type-approved according to the limit values given in row B of the table in section 5.3.1.4 of Annex I, (b) whether the procedure for identifying outlying emitters should be amended and (c) whether the procedures for in-service conformity testing should be replaced at an appropriate time by a new statistical procedure. If appropriate, the Commission will propose the necessary amendments in accordance with the procedure laid down in Article 13 of Directive 70/156/EEC.

(8)

For any vehicle, the intermediate zone is determined as follows. The vehicle shall meet the conditions given in either section 3.2.1 or section 3.2.2 and in addition, the measured value for the same regulated pollutant shall be below a level that is determined from the product of the limit value for the same regulated pollutant given in row A of the table in section 5.3.1.4 of Annex I multiplied by a factor of 2,5.

(9)

For any vehicle, the failure zone is determined as follows. The measured value for any regulated pollutant exceeds a level that is determined from the product of the limit value for the same regulated pollutant given in row A of the table in section 5.3.1.4. of Annex I multiplied by a factor of 2.5.] ] ]
