- A capability of penetrating 0,6 m or more of hot cell wall (through-the-wall operation); or b. A capability of bridging over the top of a hot cell wall with a thickness of 0,6 m or more (over-the-wall operation).
- For the somatic cell count, when the methods are validated against the reference method mentioned in point 1(b) in accordance with the protocol set out in ISO 8196 and when operated in accordance with ISO standard 13366-2 or other similar internationally accepted protocols.
- which meets the plate and somatic cell count standards laid down in Directive 92/46/EEC, Annex A, Chapter IV, paragraph A, point 3 as regards cow's milk, paragraph B, point 2 as regards buffalo milk, and paragraph C, point 2 as regards goat's and sheep's milk, and
- 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:
