Standard accreditation Tables


The traceability to national standards is the indispensable metrological base for the quality of the industrial production, and for the international acknowledgment of the certification, they are guaranteed from the possibility to carry out, in the course of the productive cycle and to the action of the test, reliable measurements.

This requirement implies that all the instrumentation is calibrated, directly or indirectly, through an uninterrupted chain of comparisons, with reference to national standards.

The Service of calibration in Italy (SIT), now ACCREDIA, denomination that characterizes the initiative been born in 1977 from part of the Primary Metrological Institute for the accreditation of calibration Centers, finds its full application with the institution of National Calibration System (SNT) through italian law 273/91, that has confirmed to the Institute of metrology G. Colonnetti of the CNR, to the National Electrotechnical Institute G. Ferraris and the ENEA Institute of metrology, the task to conserve the national standards, verifying the coherence with those of other countries and to scatter the units realized for means of such standards, through the Calibration Centers.

The Calibration Centers are accredited from the ACCREDIA L'Ente Italiano di Accreditamento that recognize therefore they technical competence, the correctness of the procedures, and primarily they guarantee the metrological traceability.

Narda STS has been accredited also for the Frequency Standard.
Narda STS has a GPS (Global Positioning System) synchronized system whose scale of time, formed from the atomic Cesium standards installed in the satellites and the earth control stations, is maintained in tightened agreement with the scale of Greenwich Mean Time U.T.C., allowing therefore the constant control of an oscillating champion of rubidium vapors.

Calibration
PMM

The calibration not only identifies the reference standards, but Narda STS guarantees the "indispensable total Traceability" in order to enter in the markets all around the world. The Narda STS laboratory of calibration offers services of calibration for all the instrumentation in the EMC field:

  • EMI receivers and Spectrum Analyzers
  • Absorbing Clamps and EM Clamps
  • Current Probes
  • R.F. Generators and Power Meters
  • ESD, Burst/Fast Transient and Surge
  • Magnetic and Electric field sensors (in TEM cells and Anechoic chamber)
  • Antennas in O.A.T.S. (Open Area Test Site)
The growing demand of calibration in the EMC field have pushed the Narda STS Center to operate in the field of the fast impulses in conformity to international norms EN and IEC, in particular for impulsive tensions and transitory currents for the calibration of:
  • ESD Simulators (Electrostatic Discharge)
  • Burst/Fast Transient Equipment
  • Surge Equipment
