Inspection / Verification

Verification confirms the operation of the measuring instrument in accordance with the regulations. For ensuring the compliance in the inspection process, standards, which have a guaranteed traceability, are used. The inspection is carried out in accordance with the ISO 17020 standard.

What measuring devices are subject to inspection / verification?

The Metrology Act (Official Gazette of the RS, No 26/05 – official consolidated text) specifies that all legal measuring instruments need to fulfil the metrologic demands set by regulations. Legal measuring instruments are instruments used for measuring in the fields of protection of human and animal health, environmental protection and general technical safety, as well as in trade in goods and services and in the processes before administrative or judicial authorities. Those are:

  • non-automatic and automatic scales,
  • weights,
  • blood pressure meters,
  • tyre pressure gauges,
  • flow meters at petrol stations,
  • industrial flow meters,
  • roller brake testing equipment at the MOT inspection.

Are there different types of verifications and verification intervals?

In the certification process of a measuring instrument, the compliance of an individual measuring instrument with the regulations and/or granted type is established. We differentiate three certification types:

  • First inspection – provided by the manufacturer or their authorised representative, it needs to be carried out before the measuring instrument is put on the market or used.
  • Regular inspection – is mandatory for measuring instruments which are being used and for measuring instruments which are saved for later use, and they need to be provided by the owner. It is carried out in specific time frames set for each individual measuring instrument.
  • Inspection after repair – is carried out after the repair or adaptation of the measuring instrument by the owner of the measuring instrument.
