An Introduction, Basic Steps, and Examples of How ALT Goes Wrong
Accelerated Life Testing, ALT, is a technique to estimate the time to failure pattern for an item. In short ALT allows us to shorten time. Done well it provides valuable insights into the future. Done poorly, it is a colossal waste of resources.
In this webinar, let’s talk about the various methods available to you for ALT. How to select the right approach given your specific understanding of the failure mechanism involved. And discuss best and a few worst practices when planning and conducing ALT.
As with any testing, ALT is an experiment. We have an hypothesis and using the test result may verify or disprove the hypothesis. A well designed test helps you make decisions and informs you about the nature of the failure mechanism’s time to failure behavior.
Done poorly, ALT provide little more than a pass / fail result with an inability to interpret the results or understand how the failure mechanisms behave over time.
Let’s discuss ALT, the many options available as you plan your next experiment, and why you should keep the focus on understanding the failure mechanism involved.
