Mixed Gas Corrosion Test Chamber

The TestEQ mixed gas corrosion test chamber exposes electronic components, contacts and assemblies to a controlled flowing mixture of corrosive gases, reproducing the corrosive atmospheres that cause contact and interconnection failures in service. The test is intended for the IEC 60068-2-60 flowing mixed gas method.

Applications

  • Electronic components, connectors and contacts
  • PCB assemblies, plated through-holes and interconnects
  • Equipment used in industrial, automotive and telecommunication environments
  • Reliability and qualification testing for corrosion resistance

Configuration and features

  • Flowing mixed gas method for IEC 60068-2-60 corrosion testing.
  • Gas concentration adjustable from 0.1 ppm to 25 ppm (range varies by gas type).
  • Controlled gas mixture, temperature and humidity for repeatable exposure conditions.
  • Supports simultaneous dosing of up to four gases (H₂S, SO₂, Cl₂ with N₂ carrier gas; NO₂ with synthetic air) for multi-pollutant interaction studies.
  • Acrylic (PMMA) viewing window for real-time monitoring of specimens.
  • Pressure monitoring system and gas sampling port for operator safety.
  • Integrated air exchange module for consistent gas distribution.
  • Programmable test profiles for batch or continuous exposure.
  • The equipment can be evolved into a sulfur dioxide corrosion test chamber and a hydrogen sulfide corrosion test chamber.
