Traduction de «Density air » (Anglais → Français) :

the following points shall be inserted:" 3a. marine diesel oil means any marine fuel which has a viscosity or density falling within the ranges of viscosity or density defined for DMB and DMC grades in Table I of ISO 8217; 3b. marine gas oil means any marine fuel which has a viscosity or density falling within the ranges of viscosity or density defined for DMX and DMA grades in Table I of ISO 8217; 3c. MARPOL means the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 rela ...[+++]ting thereto; 3d. Annex VI to MARPOL means the annex, entitled "Regulations for the Prevention of Air Pollution from Ships", that the Protocol of 1997 adds to MARPOL; 3e. SOx Emission Control Areas means sea areas defined as such by the International Maritime Organisation (IMO) under Annex VI to MARPOL ; 3f. passenger ships means ships that carry more than 12 passengers, where a passenger is every person other than:

Systems with Constant Mass Flow For systems with heat exchanger, the mass of the pollutants MGAS (g/test) shall be determined from the following equation: MGAS = u x conc x MTOTW where u = ratio between density of the exhaust component and density of diluted exhaust gas, as reported in Table 4, point 2.1.2.1 conc = average background corrected concentrations over the cycle from integration (mandatory for NOx and HC) or bag measurement (ppm) MTOTW = total mass of diluted exhaust gas over the cycle as determined in section 2.2.1 (kg) As the NOx emission depends on ambient air conditions, the NOx concentration shall be corrected for ambient ...[+++] air humidity with the factor k H , as described in section 2.2.2.

The following formulae shall be applied: where conc e,i = instantaneous concentration of the respective pollutant measured in the diluted exhaust gas (ppm) conc d = concentration of the respective pollutant measured in the dilution air (ppm) u = ratio between density of the exhaust component and density of diluted exhaust gas, as reported in Table 4, point 2.1.2.1 M TOTW,i = instantaneous mass of the diluted exhaust gas (section 2.2.1) (kg) M TOTW = total mass of diluted exhaust gas over the cycle (section 2.2.1) (kg) DF = dilution factor as determined in point 2.2.3.1.1.

The strategy will include a review of the implementation of air quality directives; improving the monitoring of air quality and information to the public as well as priorities for further actions and monitoring of "hotspots" where emission densities are especially high.

8". agglomeration" means a zone with a population concentration in excess of 250000 inhabitants or, where the population concentration is 250000 inhabitants or less, a population density per km² which for the Member State justifies the need for ambient air quality to be assessed and managed.

For the assessment of pollution in the vicinity of point sources, the number of sampling points for fixed measurement should be calculated taking into account emission densities, the likely distribution patterns of ambient air pollution and potential exposure of the population.
