3 Terms and Definitions
For the purposes of this standard, the following terms and definitions apply.
3.1
continuous emission monitoring, CEM
Continuous real-time automatic monitoring over emission concentration and amount of particulate matter and (or) gaseous pollutant emitted from stationary source (hereinafter abbreviated as CEM).
3.2
continuous emission monitoring system, CEMS
All equipment required for continuous monitoring of emission concentration and amount of particulate matter and (or) gaseous pollutant emitted from stationary source (hereinafter abbreviated as CEMS).
3.3
Spanspan (full scale)
Set set the maximum measured value of CEMS as required by actual application.
3.4
response time
the response time includes instrument response time and system response time
the instrument response time is the interval from a step increase or decrease of observed analyzer indication value to the time of indication value reaching 90% or 10% of the nominal value of standard gas
System system response time refers to the interval from the time of CEMS system sampling probe letting in standard gas to the time of analyzer indication value reaching 90% of the nominal value of standard gas, including pipeline transmission time and instrument response time.
3.5
zero drift
percentage of deviation between instrument reading and initial measurement value of zero gas to span where CEMS lets in zero gas after operation according to the time as required under the premise that the instrument is not subject to repair, maintenance and adjustment
3.6
Span span drift
percentage of deviation between instrument reading and initial measurement value of span calibration gas to span, where CEMS lets into gas after CEMS operates according to the time as required under the premise that the instrument is not subject to repair, maintenance or adjustment
