Testing

The main service of Idvorsky Laboratories is testing of electronic, IT, radio-telecommunication and many others electrical products and systems. Testing is important to prove product conformity in line with:

  • Requirements of standards (EN, IEC, CISPR, ETSI, ANSI…)
  • European Union directives (CE marking)
  • Serbian rulebooks to products (AAA mark)
  • Products certification
  • Special requirements (automotive, military, navy, railway…)
  • Customer’s particular specification (products verification, hardware design …)
