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, fuel consumption electric
energy consumption and electric ranges 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 or Annex 8 for electrified vehicles. 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 Party
1.1.2.1.
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.
The test results shall be the values which are received necessary corrections
(i.e. RCB correction, Ki correction and the other regional corrections).
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, 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 electric energy consumption for OVC-HEV CD is
not evaluated by the flowchart of Figure A6/1. It is taken as the type approval
value if declared CO2 value is accepted as the type approval value. The
evidence of correlation between declared CO2 and electric energy
consumption shall be submitted to responsible authority in advance, if
applicable.
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 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 two tests will be 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 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.
WLTP-12-16e
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 are accepted as the type
approval value. If any of the criteria on the “second test” row of Table A6/2
is not fulfilled , the declared value is taken as the type approval value if the
corresponding criterion on the “second test” row of Table A6/2 is fulfilled by
average result, and the average results are taken as the type approval value if
the corresponding criterion on the “second test” row of Table A6/2 is not
fulfilled by average result.
1.1.2.3.7.
In the case that any of the criteria of Table A6/2 is not fulfilled after the first
or second test , at the request of the manufacturer and with the approval of
the responsible authority, the values may be re-declared to the worse side in
order to reduce the required number of tests for type approval.
1.1.2.3.8.
dCO21 and dCO22 determination.
1.1.2.3.8.1.
If the charge depleting test for OVC-HEV contains two or more applicable
WLTC cycles, both dCO21 and dCO22 values in the table A6/2 shall be “1.0”.
1.1.2.3.8.2.
Without prejudice to the requirement of paragraph 1.1.2.3.8.1., the
Contracting Party shall determine dCO21 value ranging from 0.990 to 1.020,
and dCO22 value ranging from 0.995 to 1.020.
1.1.2.3.9.
For criteria pollutants, the average of all valid test results is taken as the type
approval value.

Determination of phase specific values
1.1.2.4.1.
Phase specific value for CO2
1.1.2.4.1.1.
After the total cycle declared value of CO2 is accepted, the arithmetic
average of phase specific values of test results in g/km is multiplied by the
adjustment factor (CO2_AF), to compensate the difference between the
declared value and test results. This corrected value is then taken as the type
approval value for CO2.
CO2_AF =

DL is theoretical distance of phase L [km]
DM is theoretical distance of phase M [km]
DH is theoretical distance of phase H [km]
DexH is theoretical distance of phase exH [km]
1.1.2.4.1.2.
If the total cycle declared value of CO2 is not accepted, the type approval
phase specific CO2 value is calculated by taking the arithmetic average of the
all test results for the respective phase.
1.1.2.4.2.
Phase specific value for fuel consumption
1.1.2.4.2.1.
If the total cycle declared value of CO2 is accepted, the arithmetic average of
phase specific fuel consumption value of test results in l/100km are taken as a
type approval value after multiplied by the adjustment factor (CO2_AF)
determined in the paragraph 1.1.2.4.1.1. to compensate the difference
between the declared value and test results.
1.1.2.4.2.2. If the total cycle declared value of CO2 is not accepted, the type approval
phase specific fuel consumption value is calculated by taking the arithmetic
average of the all test results for the respective phase.
1.1.2.4.3.
Phase specific value for electric energy consumption, all electric range and
equivalent all electric range.
1.1.2.4.3.1.
The phase specific electric energy consumption, all electric range and
