    1. The equivalency of the sample pair averages shall be determined by F-test and t-test statistics as described in Appendix 4 to this Regulation obtained under these laboratory, test cell and engine conditions.
    2. The equivalency of the sample pair averages shall be determined by F-test and t-test statistics as described in Appendix 4 to this Annex obtained under these laboratory, test cell and engine conditions.
    3. In the table in Annex III and in the cell for Class V close-proximity mirrors for motor vehicles of category N2 ≤ 7,5 t, the text is replaced by the following:
    4. In the table in Annex III and in the cell for Class IV wide-angle mirrors for motor vehicles of category N2 ≤ 7,5 t, the text is replaced by the following:
    5. The equivalency of the sample pair averages shall be determined by F-test and t-test statistics as described in Appendix 4 obtained under the laboratory test cell and the engine conditions described above.
    6. The total diluted exhaust gas flow over the cycle MTOTW (kg/test) shall be calculated from the measurement values over the cycle and the corresponding calibration data of the flow measurement device (V0 for PDP, KV for CFV, Cd for SSV): the corresponding methods described in section 2.2.1. may be used. If the total sample mass of particulates (MSAM) and gaseous pollutants exceeds 0,5 % of the total CVS flow (MTOTW), the CVS flow shall be corrected for MSAMor the particulate sample flow shall be returned to the CVS prior to the flow measuring device. 2.2.1. Determination of the diluted exhaust gas flow PDP-CVS system The calculation of the mass flow over the cycle, if the temperature of the diluted exhaust is kept within ± 6 K over the cycle by using a heat exchanger, is as follows: MTOTW = 1,293 x V0 x NP x (pB - p1) x273/(101,3 x T) where MTOTW mass of the diluted exhaust gas on wet basis over the cycle V 0 volume of gas pumped per revolution under test conditions (m3/rev) N P total revolutions of pump per test p B atmospheric pressure in the test cell (kPa) p 1 pressure drop below atmospheric at the pump inlet (kPa) T average temperature of the diluted exhaust gas at pump inlet over thecycle (K) If a system with flow compensation is used (i.e. without heat exchanger), the instantaneous mass emissions shall be calculated and integrated over the cycle. In this case, the instantaneous mass of the diluted exhaust gas shall be calculated as follows: MTOTW,i = 1,293 x V0 x NP, i x (pB - p1) x 273/(101,3 x T) where N P, i total revolutions of pump per time interval CFV-CVS system The calculation of the mass flow over the cycle, if the temperature of the diluted exhaust gas is kept within ± 11 K over the cycle by using a heat exchanger, is as follows:
