In September 2003, the laboratory successfully passed the audit carried out by the Slovenian Accreditation (SA) in compliance with the ISO 17025 standard. We regularly maintain the system in order to satisfy the requirements for testing and calibration laboratories in accordance with the standard, which is demonstrated at regular audits performed by the Slovenian Accreditation. The quality of the laboratory operation is assured not only by the accreditation but also by permanent comparisons done between laboratories on national and international levels.

Calibration by accredited procedures (scope of accreditation LK-020):

  • Instruments for measuring length: adjustable and screw gauges, dial indicators, gauge blocks
  • Internal and external diameter: measuring rings, inside micrometers, measuring mandrels
  • Thread quantities: screw plug gauges, screw ring gauges
  • Torque: torque wrenches / hand torque screwdrivers

After calibration in our laboratory, a certificate on calibration is issued and a certificate on accreditation of our laboratory is also enclosed.

The attachment to the accreditation certificate can be found on the website of the Slovenian Accreditation - follow the link: ANNEX

Calibration by internal procedures:

Gauge blocks, measuring rings, measuring and thread mandrels, one-sided and two-sided, thread rings, thickness gauges, adjustable gauges, micrometers, dial indicators, angles, angle meters, straight edges gauge, steel rules, spirit levels, coating thickness meters, sine meters, thermometers, thermo regulators

After calibration in our laboratory, a certificate on calibration is issued and no certificate on accreditation of our laboratory is enclosed (without a logotype of the Slovenian Accreditation (SA)).
