1. Calibration in the Ambient Air Quality Monitoring Network
The Standard Operating Procedures of the Calibration Laboratory
Bernd Heits
AQ-Workshop Bucharest, July 2008

2. Guideline Calibration Laboratory
Supply of the reference standards for the components NO, NO2, SO2, CO, O3, BTX
For the calibration of sensors for temperature, pressure, flow rate reference measuring devices are kept ready

AQ-Workshop Bucharest, July 2008

3. Guideline Calibration Laboratory
For the calibration of the balance certificated weights – according to the manual of the balance – have to be available
The traceability of the gaseous standards to the national standard is ensured

AQ-Workshop Bucharest, July 2008

4. Guideline Calibration Laboratory
The basic calibration and the function control (lack of fit test) of new and repaired monitors are done by the Calibration Laboratory
The Calibration Laboratory takes part on ring tests (national level)

5. Guideline Calibration Laboratory
The reference methods for PM10- and PM2,5-particle measurements are operated by the Calibration Laboratory
SOP: Determination of the PM10 concentration by a gravimetric method DIGITEL DHA 80
SOP: Handling of the filter
SOP: Preparation and storage of the filter

6. Guideline Calibration Laboratory
The Calibration Laboratory certificates the transfer standards (used in the network for calibrating the monitors in the stations) at least every three months.
It is recommended to check the transfer standards in the Calibration Laboratory every time before using them in the stations

AQ-Workshop Bucharest, July 2008

7. Guideline Calibration Laboratory
The (expanded) uncertainty according to the DQO of the Daughter Directives has to be determined by the Calibration Laboratory (SOP: Determination of the uncertainty for a NOx-monitor)
The head of the Calibration Laboratory is responsible for the enforcement of these tasks
