Our History

Home 9 About us 9 Our History


  • 1981

    A small unit for Electrical Calibration, including DC Voltage, DC Current, and Resistance, was established in the Royal Scientific Society.

  • 1998

    Accreditation by DKD German accreditation Service for the Electrical calibration Unit Activities complying with International standard ISO/IEC 17025, The lab. approved by JSMO to keep and maintain the national standard for electrical quantities.

  • 1999

    A new division for calibration was established to cope with industrial demand. It included the Electrical Calibration unit, and a new unit for Physical Calibration.

  • 2003

    The unit extended the scope of accreditation, and included AC Voltage and AC Current.

  • 2005

    The unit acquired a wide range of highly accurate equipment through a Japanese grant to establish 14 specialized calibration laboratories in the field of Metrology, covering electrical, physical, and mechanical measurement.

  • 2006

    RSS signed an agreement with JSMO, authorizing RSS to establish and manage JNMI to maintain and keep all national standards in one location.

  • 2009

    JNMI managed to achieve accreditation from German Accreditation Body DKD, according to DIN EN ISO 17025:2005 for calibration in the fields: Mass, Weighing Instrument, Temperature, and Dimensional Quantities.

  • 2010

    20 Accreditation bodies were converted from DKD to DAkkS accreditation body, at the end of 2011. JNMI converted its calibration certificate from DKD to DAkkS certificate.

  • 2012

    JNMI extended the scope of accreditation to 2017 in the fields of Electrical measurements, pressure, temperature, mass and balance, and dimensional measurement from the German Accreditation Body DAkkS.

  • 2016

    JNMI extended the scope of accreditation to include torque, low ohm from the German Accreditation Body DAkkS.

  • 2017

    JNMI switched to international accreditation from ILAC.

  • 2019

    JNMI extended the scope in the field of high voltage, high frequency, power factor, earth tester, insulation tester, oscilloscope, and IR thermometers from JAS national accreditation.

  • 2020

    JNMI established a new field in calibration of Gas Detectors.

  • 2021

    JNMI signed an agreement to establish a calibration lab for flow equipment in August 2021. We also extended our scope to include medical IR, Energy meters, and test benches.
