SIAD Metrology Laboratory

The Accredited Calibration Laboratory, LAT Center No. 143 was founded in 2001 by the SIAD Research Laboratory and by its experience and ten-year competence in the preparation and analysis of reference metrological mixtures.

The Accredia certified mixtures of the LAT Center are essential for guaranteeing a correct traceability chain within their measurements to: calibration centers, test laboratories, companies in the environmental and health sector and any system operating under a quality assurance system.

Accredia is the only national body authorized by the italian state to carry out accreditation activities and the results of measurements and calibrations carried out by an accredited laboratory are internationally recognized, thanks to the mutual recognition agreements stipulated between the accreditation bodies. The LAT mixtures produced and the calibrations carried out by the SIAD LAT Center refer to the samples of the International System of Units (IS) and therefore have an international value.


The Laboratory is accredited as Reference Materials Producer RMP No. 143. The LAT Center and the RMP Producer are the result of the evolution and improvement of the SIAD procedures followed to prepare the calibration mixtures. The LAT SIAD Center is accredited for the following standards:

  • UNI CEI EN ISO/IEC 17025 for gravimetric and analytical calibration of gas mixtures and analytical measurement equipment (since 2001).

  • UNI CEI EN ISO/IEC 17034 for the production of certified reference materials (since 2005).
