HALT/HASS Tests

Prevention instead of repair

Bring more Safety to your
product development and production.

Identify weak spots early

HALT (​Highly Accelerated Lifetime Testing) HALT is maximum stress and beyond.

Using HALT, weak points in the design can be identified in early development phases. With HALT, products are exposed to extreme conditions that go far beyond expected operating conditions. The goal is to improve the design by finding out under what conditions the product will fail.

HASS (Highly Accelerated Stress Screening) HASS is stress within specific limits.

HASS is used in the production phase to identify and reject defective products before they are delivered to customers. Based on the findings of HALT, we support the determination of the stress factors for HASS and thus secure ongoing production.

Our HALT/HASS procedures enable faster defect identification due to extreme mechanical and thermal stress compared to conventional service life tests. This means you can detect errors in hours instead of weeks, saving development time and costs.

Our passion for quality makes the difference

Temperaturschock 1

Temperature change

With the MPI 5000A we test the resistance of your product to rapid temperature changes. Our scope ranges from -70°C to 220°C. Thanks to high change rates, we complete up to 1.000 temperature cycles in just 48 hours.

Vibration

Mechanical load​

Our all-axis benchtop vibration table TCB-1.3 tests the robustness of your product under mechanical stress. With intensities from 1 to 60 grms and a frequency range from 3 Hz to 10.000 Hz, we typically identify mechanical weak points within 12 hours.

Operating and
destruction limits

By combining mechanical stress and temperature fluctuations, we test your product to its operating and load limits. These holistic tests provide reliable data about the resilience of your product. Typically, limits and vulnerabilities become visible within just 48 hours.
