Oxides of nitrogen definition

Oxides of nitrogen means the sum of the volume mixing ratio (ppbv) of nitrogen monoxide (nitric oxide) and nitrogen dioxide expressed in units of mass concentration of nitrogen dioxide (µg/m3);

Oxides of nitrogen means the sum of the nitric oxide and nitrogen dioxide contained in a gas sample as if the nitric oxide was in the form of nitrogen dioxide.

Oxides of nitrogen means compounds containing only nitrogen and oxygen as measured by the procedures specified in this regulation. Oxides of nitrogen are expressed quantitatively as if the NO is in the form of NO2, such that an effective molar mass is used for all oxides of nitrogen equivalent to that of NO2;

• All classes) = Organic vapours, B AUS or B1 = Acid gasses, B2 = Acid gas or hydrogen cyanide(HCN), B3 = Acid gas or hydrogen cyanide(HCN), E = Sulfur dioxide(SO2), G = Agricultural chemicals, K = Ammonia(NH3), Hg = Mercury, NO = Oxides of nitrogen, MB = Methyl bromide, AX = Low boiling point organic compounds(below 65 degC) Cartridge respirators should never be used for emergency ingress or in areas of unknown vapour concentrations or oxygen content.

• All classes) = Organic vapours, B AUS or B1 = Acid gasses, B2 = Acid gas or hydrogen cyanide(HCN), B3 = Acid gas or hydrogen cyanide(HCN), E = Sulfur dioxide(SO2), G = Agricultural chemicals, K = Ammonia(NH3), Hg = Mercury, NO = Oxides of nitrogen, MB = Methyl bromide, AX = Low boiling point organic compounds(below 65 degC) Respirators may be necessary when engineering and administrative controls do not adequately prevent exposures.

• Oxides of nitrogen: 0.7 grams per mile except diesel-fueled vehicles which have no standard.

• Emissions reduced:• Oxides of nitrogen from tailpipe emissions.• Volatile organic compounds, carbon monoxide, and carbon dioxide from tailpipe emissions.• PM10 and PM2.5 from road dust.

More Definitions of Oxides of nitrogen

Oxides of nitrogen or “NOx” means all oxides of nitrogen, except nitrous oxide, as measured by test methods approved by the Department and EPA, such as the test methods set forth at 40 CFR 60, Appendix A, methods 7 through 7E.

Oxides of nitrogen. (NOx) means compounds of nitric oxide, nitrogen dioxide, and other oxides of nitrogen. Nitrogen oxides are typically created during combustion processes and are major contributors to smog formation and acid deposition.

Oxides of nitrogen means the sum of nitric oxide and nitrogen dioxide added as parts per billion and expressed as nitrogen dioxide in micrograms per cubic meter;

Oxides of nitrogen or "NOx" means all oxides of nitrogen, including, but not limited to, nitrogen oxide and nitrogen dioxide, but excluding nitrous oxide, collectively expressed as molecular weight of nitrogen dioxide.

Oxides of nitrogen. (NOx) means compounds of nitric oxide, nitrogen dioxide, and other oxides of nitrogen. Nitrogen oxides are typically created

Oxides of nitrogen or “NOx” means all the oxides of nitrogen including, but not limited to, nitric oxide (NO) and nitrogen dioxide (NO2), except nitrous oxide (N2O).]

Oxides of nitrogen or “NOx” means air pollution usage comprised of nitric oxide and nitrogen dioxide nitrogen and oxygen compounds expressed as molecular weight of nitrogen dioxide.
