"Quality means doing it right when no one is looking." – Henry Ford
We’re known primarily for our HALT / HASS testing services. If you’re here and already know how to apply HALT, go directly to Why Choose Us below.
If you’re here because you’ve been told to look into HALT or HASS and need more information, continue reading.
HALT, Highly Accelerated Life Test or HASS, Highly Accelerated Stress Screen, do not refer to a single test. They describe testing methods that subject your product to different environmental stresses in an attempt to accelerate fatigue and identify weak links in design or processes and do so in hours instead of days, months or years. Testing takes place in specialized HALT/HASS chambers.
Typically, HALT testing takes place in four steps:
- Thermal Step Stress (Hot and Cold)
- Rapid Thermal Cycling
- Vibration Step Stress
- Combined Environment
As your testing lab, we work closely with you to determine the optimal testing methods to produce the information that you require for the specific operation of your product. And in fact, pre-test planning is very important in achieving successful test results.
