Test procedures and test conditions
1.1
Description of tests
1.1.1.
The Type 1 test is used to verify the emissions of gaseous compounds,
particulate matter, particle number, CO2 emissions, and fuel consumption, over
the applicable WLTC.
1.1.1.1.
The tests shall be carried out according to the method described in paragraph
1.2. of this Annex. Exhaust gases, particulate matter and particle number shall
be sampled and analysed by the prescribed methods.
1.1.2.
The number of tests shall be determined as shown in the flowchart of Figure
A6/1. Criteria pollutants are the emissions of gaseous compounds, particulate
matter, and particle number which are regulated by the Contracting Party. The
limit value is the maximum allowed value for the respective criteria pollutant,
as defined by the Contracting Party1.1.2.1. The flowchart in Figure A6/1 shall
only be applicable to total cycle values i.e. the whole applicable WLTC, not to
phase specific values.
1.1.2.2.
For vehicles powered by an internal combustion engine only, and which are
equipped with periodically regenerating systems as defined in paragraph 3.8.1.
of this Regulation, the results are multiplied by the factor Ki obtained from
Appendix 2 of this Annex before being evaluated in the flowchart of Figure
A6/1 .
1.1.2.3.
Determination of total cycle values
1.1.2.3.1.
If during any of the tests a criteria pollutant limit is exceeded, the vehicle is
rejected. No further tests are then required.
1.1.2.3.2.
Depending on the vehicle type, the manufacturer declares the total cycle value
of CO2, fuel consumption, electric energy consumption, all electric range and
equivalent all electric range according to Table A6/1, .
1.1.2.3.3.
The declared value of the fuel consumption and the electric energy
consumption for OVC-HEV are not evaluated by the flowchart of Figure A6/1.
They are taken as the type approval value if declared CO2 value is accepted as
the type approval value. The evidence of correlation between declared CO2,
fuel consumption and –if applicable- electric consumption shall be submitted
to responsible authority in advance.
1.1.2.3.4.
If after the first test all criteria on the “first test” row of Table A6/2 are fulfilled,
all values declared by the manufacturer including declared fuel consumption
and electric energy consumption for OVC-HEV are accepted as the type
approval value. If any of the criteria on the “first test” row of Table A6/2 is not
fulfilled, a second test is run on the same vehicle.
1.1.2.3.5.
After the second test, the average results of both test will be calculated. If all
criteria on the “second test” row of Table A6/are fulfilled by these average
results, all values declared by the manufacturer including declared fuel
consumption and electric energy consumption for OVC-HEV are accepted as
the type approval value. If any of the criteria on the “second test” row of Table
A6/2 is not fulfilled, a third test is run on the same vehicle.
1.1.2.3.6.
After third test, the average results of the three tests is calculated. If all criteria
on the “second test” row of Table A6/2 are fulfilled by these average results,
all values declared by the manufacturer including declared fuel consumption
and electric energy consumption for OVC-HEV are accepted as the type
approval value. If any of the criteria on the “second test” row of Table A6/1 is
not fulfilled, , the average results are taken as the type approval value.
1.1.2.3.7.
In the case that any of the criteria of Table A6/2 is not fulfilled, the
manufacturer may choose to accept the average result of all valid tests as type
approval value.
1.1.2.3.8.
For criteria pollutants, the average of all valid test results is taken as the type
approval value.
