Highly Accelerated Stress Screening (HASS)

HASS (Highly Accelerated Stress Screening) is a very effective production screening method used to find manufacturing defects, problems, and monitor processes. The proper use of HASS testing can reduce screening time & costs, improve process control and improve overall quality.

Equipment Capabilities:

  • Temperatures from -100°C to +200°C (-148°F to +392°F).
  • Temperatures can be raised or lowered up to 60°C (140°F) per minute.
  • Vibration input levels up to 60 Grms with six degrees of freedom.
  • Additional loads such as electrical, fluid pressure, etc. can be applied to parts inside the chamber simultaneously with temperature and vibration.
