HIGHLY ACCELERATED LIFE TESTING
HALT & HASS Test Chamber
HALT (Highly Accelerated Life Test) and HASS (Highly Accelerated Stress Screen) test chambers are specialized testing systems used to evaluate product robustness and reliability by applying extreme environmental stresses to expose design flaws and manufacturing defects early in the product lifecycle.

DESIGN PHASE TESTING
HALT Test Chamber
Used during the design and development phase to uncover design weaknesses and failure points.
02
Key Features
- Extreme Temperature Cycling: Operates in broad temperature ranges, often from -100°C to +200°C. Rapid thermal transitions (up to 60°C/minute) using liquid nitrogen cooling and high-capacity heaters.
- Multi-Axis Vibration: Applies simultaneous random vibration in 6 degrees of freedom (DOF). Frequency range typically from 10 Hz to 10,000 Hz to simulate real-world conditions.
- Step-Stress Testing: Gradually increases stress levels (temperature, vibration) until the product fails. Helps determine operational and destruction limits.
- Combined Environmental Stresses: Simultaneously applies thermal and vibration stresses to mimic extreme real-world conditions.
ACCELERATED RELIABILITY WORKFLOW
Stress. Observe. Improve.
HALT exposes weaknesses early so engineering teams can improve product robustness before production.
01
Apply Stress
Increase temperature and vibration beyond normal operating conditions.
02
Observe Failure
Identify operational limits, failure mechanisms and design weaknesses.
03
Improve Design
Use findings to strengthen the product before moving toward production.
PRODUCTION PHASE TESTING
HASS Test Chamber
Used during the production phase to screen for manufacturing defects.
01
Purpose
- Used during the production phase to screen for manufacturing defects.
- Ensures consistency and reliability of mass-produced items without causing damage.
02
Key Features
- Stress Levels Defined by HALT: Operates within stress parameters identified during HALT, ensuring the product is not damaged but still challenged.
- High Throughput: Allows batch testing of products for efficient screening during manufacturing.
