Testing laboratory


Testing laboratory

  • Disposition of climatic and temperature chambers.
  • Mechanical testing including vibration, shock, and spraying.
  • Electromagnetic Near-Field discrete scanning in front of the tested antenna aperture.

T-CZ extends the capabilities of its corporate testing laboratory to provide a range of services in climatic and mechanical testing. Our testing procedures adhere to both Czech and international standards, and we are fully equipped to accommodate specific customer requirements. For example, we can recommend and execute tests in compliance with a variety of standards, including ČSN EN 60068, ETS 300 019, MIL STD 810, ČOS 999905, and ČOS 999902.
