Twinning Project RO2006/IB/EN/09 8 Saxony-Anhalt State Environmental Protection Agency Wolfgang GarcheBukarest Estimation of uncertainty of measurements A calibration laboratory shall have and apply a procedure to estimate the uncertainty of measurements for all calibrations and types of calibration. (EN ISO Air quality – Guidelines for estimating measurement uncertainty ENV Guide to the Expression of Uncertainty in Measurement (GUM) )

Twinning Project RO2006/IB/EN/09 9 Saxony-Anhalt State Environmental Protection Agency Wolfgang GarcheBukarest Equipment  Laboratory shall be furnished with all items of sampling, measurement and test equipment for the correct performance of the tests and/or calibrations (5.5.1).  Equipment used for testing, calibration and sampling shall be capable of achieving the required accuracy and shall comply with the specifications relevant for the tests and/or calibrations concerned (5.5.2).  All new equipment purchased for implementation of this Directive must comply with the reference method or equivalent by two years after the date of entry into force of this Directive.  All equipment used in fixed measurements must comply with the reference method or equivalent by five years after the date of entry into force of this Directive Directive on ambient air quality and cleaner air for Europe

Twinning Project RO2006/IB/EN/09 10 Saxony-Anhalt State Environmental Protection Agency Wolfgang GarcheBukarest Measurement traceability The appropriate competent authorities and bodies designated pursuant to Article 3 shall ensure: that all measurements undertaken in relation to the assessment of ambient air quality pursuant to Articles 6 and 9 are traceable in accordance with the requirements set out in Section of the ISO/IEC 17025:2005  If calibration is a dominant factor of the uncertainty budget the requirements of should be strictly followed ( )  The programme for calibration of equipment shall be designed and operate so as to ensure that calibrations and measurements are traceable to the International System of Units (SI) Directive on ambient air quality and cleaner air for Europe

Twinning Project RO2006/IB/EN/09 11 Saxony-Anhalt State Environmental Protection Agency Wolfgang GarcheBukarest  Traceability can be established by means of an unbroken chain of calibrations or comparisons. The link to SI units may be achieved by reference to national standards.  When using external calibration services, traceability shall be assured by the use of services from laboratories that can demonstrate competence, measurement capability and traceability.  Calibration certificates shall contain the measurement results, including the measurement uncertainty and/or a statement of compliance with a identified meteorological specification.
