5.                     SPECIFICATIONS AND TESTS

Note:  As an alternative to the requirements of this paragraph, vehicle manufacturers whose world-wide annual production is less than 10,000 units may obtain approval on the basis of the corresponding technical requirements specified in: the California Code of Regulations, Title 13, Paragraphs 1960.1 (f) (2) or (g) (1) and (g) (2), 1960.1 (p) applicable to 1996 and later model-year vehicles, 1968.1, 1976 and 1975, applicable to 1995 and later model year light-duty vehicles (California Code of Regulations is published by Barclays Publishing).

5.1.                  General  

5.1.1.               The components liable to affect the emission of pollutants shall be so designed, constructed and assembled as to enable the vehicle, in normal use, despite the vibration to which they may be subjected, to comply with the provisions of this Regulation.

5.1.2.               The technical measures taken by the manufacturer shall be such as to ensure that in conformity with the provisions of this Regulation, exhaust gas and evaporative emissions are effectively limited throughout the normal life of the vehicle and under normal conditions of use. This will include the security of those hoses and their joints and connections, used within the emission control systems, which shall be so constructed as to conform with the original design intent.  For exhaust emissions, these provisions are deemed to be met if the provisions of paragraphs 5.3.1.4. and 8.2.3.1. respectively are complied with.  For evaporative emissions, these conditions are deemed to be met if the provisions of paragraphs 5.3.1.4. and 8.2.3.1. respectively are complied with.

5.1.2.1.            The use of a defeat device is prohibited.

5.1.3.               Inlet orifices of petrol tanks

5.1.3.1.            Subject to paragraph 5.1.3.2., the inlet orifice of the petrol tank shall be so designed as to prevent the tank from being filled from a petrol pump delivery nozzle which has an external diameter of 23.6 mm or greater.

5.1.3.2.            Paragraph 5.1.3.1. shall not apply to a vehicle in respect of which both of the following conditions are satisfied, i.e.:

5.1.3.2.1.         the vehicle is so designed and constructed that no device designed to control the emission of gaseous pollutants shall be adversely affected by leaded petrol, and;

5.1.3.2.2.         the vehicle is conspicuously, legibly and indelibly marked with the symbol for unleaded petrol, specified in ISO 2575:1982, in a position immediately visible to a person filling the petrol tank. Additional markings are permitted.

5.1.4.               Provision shall be made to prevent excess evaporative emissions and fuel spillage caused by a missing fuel filler cap.

This may be achieved by using one of the following:

5.1.4.1.            an automatically opening and closing, non-removable fuel filler cap;

5.1.4.2.            design features which avoid excess evaporative emissions in the case of a missing fuel filler cap;

5.1.4.3.            any other provision which has the same effect. Examples may include, but are not limited to, a tethered filler cap, a chained filler cap or one utilising the same locking key for the filler cap as for the vehicle's ignition. In this case, the key shall be removable from the filler cap only in the locked condition.

5.1.5.               Provisions for electronic system security

5.1.5.1.            Any vehicle with an emission control computer shall include features to deter modification, except as authorised by the manufacturer.  The manufacturer shall authorise modifications if these modifications are necessary for the diagnosis, servicing, inspection, retrofitting or repair of the vehicle.  Any reprogrammable computer codes or operating parameters shall be resistant to tampering and afford a level of protection at least as good as the provisions in ISO DIS 15031-7, dated October 1998 (SAE J2186 dated October 1996), provided that the security exchange is conducted using the protocols and diagnostic connector as prescribed in paragraph 6.5. of Annex II, Appendix 1.  Any removable calibration memory chips shall be potted, encased in a sealed container or protected by electronic algorithms and shall not be changeable without the use of specialised tools and procedures.

5.1.5.2.            Computer-coded engine operating parameters shall not be changeable without the use of specialised tools and procedures (e.g. soldered or potted computer components or sealed (or soldered) computer enclosures).

5.1.5.3.            In the case of mechanical fuel-injection pumps fitted to compression-ignition engines, manufacturers shall take adequate steps to protect the maximum fuel delivery setting from tampering while a vehicle is in service.

5.1.5.4.            Manufacturers may apply to the approval authority for an exemption to one of these requirements for those vehicles which are unlikely to require protection. The criteria that the approval authority will evaluate in considering an exemption will include, but are not limited to, the current availability of performance chips, the high-performance capability of the vehicle and the projected sales volume of the vehicle.

5.1.5.5.            Manufacturers using programmable computer code systems (e.g. Electrical Erasable Programmable Read-Only Memory, EEPROM) shall deter unauthorised reprogramming. Manufacturers shall include enhanced tamper protection strategies and write protect features requiring electronic access to an off-site computer maintained by the manufacturer. Methods giving an adequate level of tamper protection will be approved by the authority.

5.1.6.               It shall be possible to inspect the vehicle for roadworthiness test in order to determine its performance in relation to the data collected in accordance with paragraph 5.3.7. to this Regulation.  If this inspection requires a special procedure, this shall be detailed in the service manual (or equivalent media).  This special procedure shall not require the use of special equipment other than that provided with the vehicle.

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.).

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

5.3.5.1.2.               The test consists of the four elementary urban driving cycles of Part One of the Type I test. The Part One test is described in Annex 4, Appendix 1 and illustrated in figures 1/1, 1/2 and 1/3 of the Appendix. The low ambient temperature test lasting a total of 780 seconds shall be carried out without interruption and start at engine cranking.

5.3.5.1.3.               The low ambient temperature test shall be carried out at an ambient test temperature of 266 K (-7°C). Before the test is carried out, the test vehicles shall be conditioned in a uniform manner to ensure that the test results may be reproducible. The conditioning and other test procedures are carried out as described in Annex 8.

5.3.5.1.4.               During the test, the exhaust gases are diluted and a proportional sample collected. The exhaust gases of the vehicle tested are diluted, sampled and analysed, following the procedure described in Annex 8, and the total volume of the diluted exhaust is measured. The diluted exhaust gases are analysed for carbon monoxide and hydrocarbons.

5.3.5.2.                  Subject to the requirements in paragraphs 5.3.5.2.2. and 5.3.5.3. the test shall be performed three times. The resulting mass of carbon monoxide and hydrocarbon emission shall be less than the limits shown in the table below:

266 K (-7 °C)	15	1.8

5.3.5.2.1.               Notwithstanding the requirements of paragraph 5.3.5.2., for each pollutant, not more than one of the three results obtained may exceed the limit prescribed by not more than 10 per cent, provided the arithmetical mean value of the three results is below the prescribed limit. Where the prescribed limits are exceeded for more than one pollutant, it is immaterial whether this occurs in the same test or in different tests.

5.3.5.2.2.               The number of tests prescribed in paragraph 5.3.5.2. may, at the request of the manufacturer, be increased to 10 if the arithmetical mean of the first three results is lower than 110 per cent of the limit. In this case, the requirement after testing is only that the arithmetical mean of all 10 results shall be less than the limit value.

5.3.5.3.                  The number of tests prescribed in paragraph 5.3.5.2. may be reduced according to paragraphs 5.3.5.3.1. and 5.3.5.3.2.

5.3.5.3.1.               Only one test is performed if the result obtained for each pollutant of the first test is less than or equal to 0.70 L.

5.3.5.3.2.               If the requirement of paragraph 5.3.5.3.1. is not satisfied, only two tests are performed if for each pollutant the result of the first test is less than or equal to 0.85 L and the sum of the first two results is less than or equal to 1.70 L and the result of the second test is less than or equal to L.

(V₁ £ 0.85 L and V₁ + V₂ £ 1.70 L and V₂ £ L).

5.3.6.   Type V test (Durability of anti-pollution devices)

5.3.6.1.                  This test shall be carried out on all vehicles referred to in paragraph 1. to which the test specified in paragraph 5.3.1. applies. The test represents an ageing test of 80,000 kilometres driven in accordance with the programme described in Annex 9 on a test track, on the road or on a chassis dynamometer.

5.3.6.1.1.               Vehicles that can be fuelled either with petrol or with LPG or NG should be tested in the Type V test on petrol only.  In that case the deterioration factor found with unleaded petrol will also be taken for LPG or NG.

5.3.6.2.                  Notwithstanding the requirement of paragraph 5.3.6.1., a manufacturer may choose to have the deterioration factors from the following table used as an alternative to testing to paragraph 5.3.6.1.

Engine category	Deterioration factors by pollutant
CO	HC	NOx	HC + NOx(1)	Particulates
Positive- ignition engine	1.2	1.2	1.2	-	-
Compression-ignition engine	1.1	-	1	1	1.2

(1)  For compression ignition engined vehicles

At the request of the manufacturer, the technical service may carry out the Type I test before the Type V test has been completed using the deterioration factors in the table above. On completion of the Type V test, the technical service may then amend the type approval results recorded in Annex 2 by replacing the deterioration factors in the above table with those measured in the Type V test.

5.3.6.3.                  Deterioration factors are determined using either procedure in paragraph 5.3.6.1. or using the values in the table in paragraph 5.3.6.2. The factors are used to establish compliance with the requirements of paragraphs 5.3.1.4. and 8.2.3.1.

5.3.7.   Emission data required for roadworthiness testing

5.3.7.1.                  This requirement applies to all vehicles powered by a positive-ignition engine for which type approval is sought in accordance with this amendment.

5.3.7.2.                  When tested in accordance with Annex 5 (Type II test) at normal idling speed:

(a)      the carbon monoxide content by volume of the exhaust gases emitted shall be­­ recorded,

(b)      the engine speed during the test shall be recorded, including any tolerances.

5.3.7.3.                  When tested at 'high idle' speed (i. e. > 2,000 min.^-1)

(a)      the carbon monoxide content by volume of the exhaust gases emitted shall be recorded,

(b)      the Lambda value (*) shall be recorded.

(c)      the engine speed during the test shall be recorded, including any tolerances.

(*)      The Lambda value shall be calculated using the simplified Brettschneider equation as follows:

where:

[ ]         =   Concentration in per cent volume

K1        =   Conversion factor for NDIR measurement to FID measurement (provided by manufacturer of measuring equipment)

H_cv       =    Atomic ratio of hydrogen to carbon - for petrol  1.73

- for LPG    2.53

- for NG      4.0

O_cv       =    Atomic ratio of oxygen to carbon                   - for petrol  0.02

- for LPG    0.0

8.2.3.               If a Type I test is to be carried out and a vehicle type approval has one or several extensions, the tests will be carried out either on the vehicle described in the initial information package or on the vehicle described in the information package relating to the relevant extension.

8.2.3.1.            Checking the conformity of the vehicle for a Type I test.

After selection by the authority, the manufacturer shall not undertake any adjustment to the vehicles selected.

For hybrid electric vehicles (HEV), the tests shall be carried out under the conditions determined in Annex 14:

–        For OVC vehicles, the measurements of emissions of pollutants shall be carried out with the vehicle conditioned according to condition B of the Type I test for OVC hybrid vehicles.

–        For NOVC vehicles, the measurements of emissions of pollutants shall be carried out under the same conditions as in the Type I test for NOVC vehicles.

8.2.3.1.1.         Three vehicles are selected at random in the series and are tested as described in paragraph 5.3.1. The deterioration factors are used in the same way. The limit values are given in paragraph 5.3.1.4.

8.2.3.1.1.1.      In the case of periodically regenerating systems as defined in paragraph 2.20., the results shall be multiplied by the factors K_i obtained by the procedure specified in Annex 13 at the time when type approval was granted.

At the request of the manufacturer, testing may be carried out immediately after a regeneration has been completed.

8.2.3.1.2.         If the authority is satisfied with the production standard deviation given by the manufacturer in accordance with paragraph 8.2.1. above, the tests are carried out according to Appendix 1.

If the authority is not satisfied with the production standard deviation given by the manufacturer in accordance with paragraph 8.2.1. above, the tests are carried out according to Appendix 2.

8.2.3.1.3.         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.

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 2 below).

8.2.3.2.            Notwithstanding the requirements of paragraph 3.1.1. of Annex 4, the tests will be carried out on vehicles coming straight off the production line.

8.2.3.2.1.         However, at the request of the manufacturer, the tests may be carried out on vehicles which have completed:

–        a maximum of 3,000 km for vehicles equipped with a positive-ignition engine, or

–        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 shall undertake not to make any adjustments to these vehicles.

Figure 2

8.2.3.2.2.               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:

(a)        the pollutant emissions (Type I) will be measured at zero and at "x" km on the first tested vehicle,

(b)        the evolution coefficient of the emissions between zero and "x" km will be calculated for each of the pollutants:

Emissions "x" km / Emissions zero km

This may be less than 1,

(c)        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:

(i)       the values at 'x' km for the first vehicle,

(ii)       the values at zero km multiplied by the evolution coefficient for the other vehicles.

8.2.3.2.3.               All these tests may be conducted with commercial fuel. However, at the manufacturer's request, the reference fuels described in Annex 10 may be used.

(i)         If a Type III test is to be carried out, it shall be conducted on all vehicles selected for the Type I COP test. The conditions laid down in paragraph 5.3.3.2. shall be complied with. For hybrid electric vehicles (HEV), the tests shall be carried out under the conditions determined in Annex 14, paragraph 5.

1/        On the basis of actual in-service data to be supplied before 31 December 2003, the requirements of this paragraph 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 paragraph 5.3.1.4. of this Regulation, (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 necessary amendments will be proposed.

2/        For any vehicle, the “intermediate zone” is determined as follows. The vehicle shall meet the conditions given in either paragraph 3.2.1. or paragraph 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 paragraph 5.3.1.4. of this Regulation multiplied by a factor of 2.5.

3/        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 paragraph 5.3.1.4. of this Regulation multiplied by a factor of 2.5.

1/                It should be noted that the time of two seconds allowed includes the time for changing gear and, if necessary, a certain amount of latitude to catch up with the cycle.

1/                For HEV, and until uniform technical provisions have been established, the manufacturer will agree with the technical service concerning the status of the vehicle when performing the test as defined in this appendix.
