Which calibrations offers E+E?

Sophisticated metrology is one of the fundamental prerequisites for quality and progress in trade, industry, science, health and environmental protection.
"National standards" are at the pinnacle of the hierarchy of measuring equipment.

Every industrial nation has an authority that provides this measurement standard and verifies its accuracy by international comparison measurements.

In Austria this is the task of BEV - the National Metrology Institute. E+E Elektronik as a „designated laboratory" is commissioned to provide and further develop the national standard for humidity.

Thanks to the direct traceability to an NMI (National Metrology Institute), a BEV certificate is of particular interest to accredited calibration authorities.

Based on the agreements between the members of EA (European Cooperation for Accreditation) and ILAC (International Laboratory Accreditation Cooperation), calibration certificates issued by E+E conform to worldwide recognized standards.

Calibration in a designated NMI laboratory

These national standards must be compared with the standards of other countries by means of „key comparisons" in order to be recognized internationally in line with the CIPM-MRA (international Mutual Recognition Agreement).

The BEV calibration lab covers particularly
extraordinary calibrations for special humidity measuring equipment.

Due to direct traceability with the NMI (National Metrology Institute), an NMI certificate is of
particular interest to accredited calibration

For the highest measurement authority in a country there is the opportunity to build expertise about the measurement variables. In addition, within the frame of the technical possibilities
qualified measurements can be performed
beyond the OEKD accreditation.

Calibrations in an accredited OEKD laboratory

The E+E OEKD laboratory is accredited in
accordance with EN ISO/IEC 17025.

The Austrian Federal Ministry of Economics, Family and Youth (BMWFJ) is responsible for the accreditation and supervision.

Each OEKD certificate must be approved by an authorised signatory. OEKD certificates are
issued for measuring instruments, which require a particularly high degree of reliability (e.g. works standards) or where measurements need to be traceable.

OEKD on-site calibration

On-site calibration may be required forn certain process and quality-relevant measuring points.

For this purpose, E+E offers a manufacturer-independent
calibrationservice for the physical quantities humidity and 

The on-site service covers the calibration of stationary and
portable instrumentation as well as climate chambers with
specific customer requirements.

ISO Calibration to the E+E standard

ISO calibrations are comparative measurements taken with
E+E reference instruments or systems, which are traceable to international standards with known measuring uncertainties. Comparisons take place based on internal procedures, which meet the requirements of ISO 9000 and ISO TS16949.

This measurement provides a low-priced verification of the calibration-status of an instrument utilizing high-quality measuring equipment. It verifies the function of an instrument, specifying the measurement error.

In specific cases requirements in accordance with the following standards can be covered:

  • ISO10012-1
  • ISO/QS 9000
  • GMP
  • CFR
  • VDA ISO TS 16949
