The standard state temperature is 273 K and the pressure is 101,325 Pa.

The State Environmental Protection Administration has stipulated the "Emission Standards for Cooking Fumes" as follows:

Emission standards for cooking fumes;

1. Scope. It stipulates the maximum allowable emission concentration of oil fumes, odor concentration, minimum removal efficiency of oil fume purification facilities, and minimum emission height of oil fume exhaust cylinders in catering enterprises. This standard is applicable to the management of fume emissions from existing catering units in urban built-up areas, nature reserves and scenic spots, as well as the design, environmental impact assessment, environmental protection acceptance and management of fume emissions during the operation of new, expanded and reconstructed catering units; The internal staff canteens of food processing units and non-operating units that emit oil fumes shall be implemented with reference to this standard.

This standard does not apply to residential household fume emissions.

2. Standard status. The state at a temperature of 273K and a pressure of 101325Pa. The concentration standard value and exhaust air volume specified in this standard are the dry flue gas values under the standard state.

3. Cooking fumes. Mixtures of volatile oils, organic matter, and thermal oxidation or pyrolysis during food cooking and food production and processing.

4. Fume purification equipment. Equipment for purifying oil fumes generated in food cooking and food production and processing.
