HALT - Combined Environment
Combined Environment is the last, and most destructive of the tests applied during a HALT. The temperature cycling profile used for Rapid Thermal Transitions is combined with the vibration step stress profile to make the ultimate thermal and vibration stress test.
Brief Combined Environment Summary
The vibration level is traditionally set to one fifth of the operating limit attained during the vibration step stress, and the first thermal cycle is conducted. The product is continuously monitored for functionality throughout the entire process.
There are many varieties of combined environment testing, and our consultants will work with your organization to ensure the appropriate test is applied.
