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: vernier calliper gauges, 2 point micrometers, dial indicators, gauge blocks, gap gauges
  • Internal and external diameter: measuring rings, inside micrometers, plug gauges
  • Thread quantities: screw plug gauges, screw ring gauges, screw taper plug gauges
  • Torque: torque wrenches

After each calibration, a certificate with the Slovenian Accreditation logo is prepared, which means that the service is accredited.

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

Calibration by internal procedures:

In addition to calibrations according to accredited procedures, we also offer calibrations according to our internal laboratory procedures for (test strips, tape gauges, squares 90°, protractors, spirit levels, Knife edge straight edges, ...)

After calibration in our laboratory, a certificate on calibration is issued without a logotype of the Slovenian Accreditation (SA).

Technical Cleanliness tests and Porosity tests:

In the field of testing, the laboratory deals with the analysis of technical cleanliness on products according to the ISO16232 standard or VDA19. In the case of porosity, the pores that appear in the products are analyzed. Both analyzes are performed on a measuring microscope.

Additional laboratory services:

  • Measurement of thickness of electroplating coatings with an X-ray unit,
  • Roughness measurement,
  • Measurement on a tool microscope,
  • Measurement on the optical measuring device Smart Scope
  • Adjustment of gap gauges,
  • Servicing of measuring equipment
  • Rental of control equipment
