Laboratory for Mechanical and Technological Testing


The Laboratory for Mechanical and Technological Testing has been operating since the year 1961, when the Institute was estabilished, in different organizational forms and under different names.

Initially, the Laboratory was an incoming quality control department for the KONČAR Group companies, later it was providing infrastructure support to development and production. Nowadays it provides wide scope of services and supports in testing of materials.

Technical capabilities:

  • Mechanical and technological testing of materials
  • Metalographic  and  fractographic examinations
  • Non destructive testing (NDT)
  • Climate testings
  • Testing of anticorrosion coatings
  • Vacuum leakage testing
  • Helium leak testing
  • Welders and brazers certification
  • Specification and approval of welding procedures
  • Vacuum heat treating , sintering and outgasing of materials
  • Solutions in field of special industrial equipment
  • Expert services in the field of materials, heat treating, welding, brazing and vacuum technologies.


Testing scope and equipment:

  • Static tensile test ; 5 kN, 150 kN, 500 kN load
  • Charpy impact test +200 to -400 C (300 hammer)
  • Hardness testing (Brinell, Vickers, Knoop, Rockwell, Shore), semimicro and micro hardness testing (Knoop)
  • Testing with successive bending
  • Deformability testing (Erichssen test)
  • Optical microscopy, metalographic replication
  • X-ray, Ultrasonic , Magnetic particle and Penetrating liquid testing and visual control
