    Software validation

    • The laboratory is accredited according to ČSN EN ISO/IEC 17025:2018 (ISO/IEC 17025:2017) for testing metrology software in measuring instruments according to:
      • WELMEC Guide 7.2
      • OIML D 31
      • OIML R 49
      • OIML R 117
      • OIML R 139
      • EN 45501:2015, Annex E, G
    • The department provides services in the framework of type approval according to MID (Measurement Instruments Directive) 2004/22/EC, which sets the basic requirements for measuring instruments operating in the EU. Software assessment is performed according to the recommendations of WELMEC Software Guide 7.2.
    • We deal with measuring instruments regulated by the MID Directive, which are:
      • water meters
      • gas meters and gas quantity calculators
      • electricity meters for measuring active energy
      • thermal energy meters
      • metering systems for measuring quantities of liquids other than water
      • scales with automatic operation
      • taxameters
      • instruments for measuring dimensions

                  and their add-on modules/instruments which further process or store the measured data.

    • We also perform software assessments of measuring instruments according to national legislation and OIML requirements.
    • The laboratory also participates in the determination of software requirements, their validation and verification both at national, European (WELMEC manuals) and world level (OIML scheme).
    • We participate in international projects focused on software and digitalisation in metrology. We are working on a systematic solution for the implementation of technologies supporting digitalization, BIG DATA issues and the area of digital transformation for metrology and Industry 4.0. We are also analyzing the needs and impacts of digitalization in the regulated sphere.
