[3.4.4.3. 	Alternative Shortened Type 6 test procedure
3.4.4.3.1. 	Speed trace and breaks
The test shall be performed by driving consecutive applicable test cycles until the break-off criterion according to paragraph 3.4.4.1.3. of this Annex is reached. Breaks for the driver and/or operator are permitted only between test cycles and with a maximum total break time of 10 minutes for Type 1 tests and [10 minutes] for Type 6 tests. During the break, the powertrain and cabin heater (if applicable) shall be switched off.
3.4.4.3.2.	REESS current and voltage measurement
From the beginning of the test until the break-off criterion is reached, the electric current of all REESSs and the electric voltage of all REESSs shall be determined according to Appendix 3 to this annex.
3.4.4.3.3.	Break-off criterion
The break-off criterion is reached when the vehicle exceeds the prescribed speed trace tolerance as specified in paragraph 2.6.8.3. of Annex 6 for 4 consecutive seconds or more in the second constant speed segment CSS. The accelerator control shall be deactivated. The vehicle shall be braked to a standstill within 60 seconds.
3.4.4.4	Speed trace
The alternative shortened Type 6 test procedure consists of one dynamic segments (DS), followed by one constant speed segments (CSS) as shown in Figure A8/2.1.

DS

The dynamic segment DS is used to calculate the energy consumption of the phase considered, the applicable WLTP city cycle and the applicable WLTP test cycle. 
3.4.4.4.1.1.	 Dynamic segment
The dynamic segment consists of 3 applicable WLTP test cycle in accordance with paragraph 1.4.2.1. of Annex 8. 
3.4.4.4.1.2. 	Constant speed segment
If the interpolation method is applied, the same constant speed shall be applied within the interpolation family. 
(a) Speed specification
The minimum speed of the constant speed segments shall be 100 km/h. At the request of manufacturer and with approval of the approval authority, a higher constant speed in the constant speed segments may be selected.
The acceleration to the constant speed level shall be smooth and accomplished within 1 minute after completion of the dynamic segments and, in the case of a break according to Table A8/4, after initiating the powertrain start procedure.
If the maximum speed of the vehicle is lower than the required minimum speed for the constant speed segments according to the speed specification of this paragraph, the required speed in the constant speed segments shall be equal to the maximum speed of the vehicle.
(b) Distance determination of CSS 
The length  of constant speed segment CSS may be calculated using the following equation:

where:
dCSS	is the length of constant speed segment CSS, km;
 	is the estimated pure electric range of the considered PEV at low temperature, km;
	is the length of the applicable WLTC cycle, km

3.4.4.4.1.3.	Breaks
Breaks for the driver and/or operator are permitted only in the constant speed segments as prescribed in Table A8/4.1.

Note: During a break, the powertrain shall be switched off.	

4.4.2.3.	Determination of the pure electric ranges when the alternate shortened Type 6 test procedure is applied
4.4.2.3.1.	The pure electric range for the applicable WLTP test cycle PERLT.WLTC for PEVs shall be calculated from the shortened Type 6 test as described in paragraph 3.4.4.2. of this annex using the following equations:

	is the weighting factor for the applicable WLTP test cycle of DSj of the shortened Type 6 test procedure;
and:

where:
	is the weighting factor for the applicable WLTP test cycle of DSj of the shortened Type 6 test procedure;
	is the electric energy change of all REESSs during the applicable 1st WLTP test cycle of the alternate shortened Type 6 test procedure, Wh.
