3 Terms and definitions
The following terms and definitions are applicable to this specification:
3.1 Combustion furnace
A device for treating daily waste by high-temperature oxidation.
3.2 Non hazardous industrial solid waste
Solid waste generated in industrial production activities, with the exception of hazardous waste.
3.3 Existing municipal solid waste incinerator

3.4 New municipal solid waste incinerator
New daily waste incinerators, reconstruction and expansion of VOCs online monitoring system approved in the environmental impact assessment document after the implementation of this specification.
3.5 Standard conditions
The gas condition when the temperature is 273.16K and the pressure is 101.325kPa.
3.6 Average value
During the sampling period, the average values of the test values of at least three samples shall be collected at equal time intervals (Zui is less than 30 minutes and Zui is more than 8 hours).
3.7 Hourly average value
The arithmetic mean value of pollutant concentration in any hour; Or collect the arithmetic mean of test values of 4 samples at equal time intervals within 1 hour.
3.8 Daily average value
