Alternatives to a Long ALT

Jan 15, 2025

Fred Schenkelberg, a speaker and expert in accelerated life testing, discusses the lengthy process of traditional testing methods. He explores alternatives that streamline the testing process, suggesting that sometimes estimating product lifespan may not be necessary. The conversation dives into the complexities of understanding failure mechanisms and how leveraging existing knowledge can improve reliability assessments. Schenkelberg emphasizes the importance of balancing timely results with accurate data collection in product development.

Life testing a product or component, at times, involves months and months of testing. Even accelerated life testing can take a long time, given the limitation on our ability to cause the proper acceleration for meaningful results. So, what is one to do if waiting 3 months for test results is unacceptable?

Let's explore a few alternatives along with the pros and cons. We examine using our knowledge and the knowledge of others to streamline the testing or avoid it altogether. We also need to consider why we need to estimate life in the first place. Sometimes, estimating the life of something is not all that useful or valuable. This Accendo Reliability webinar was originally broadcast on 14 January 2025.

Select the Right Accelerated Life Test Approach

Let's explore how to select the right ALT approach. Getting meaningful results on time is important, as is minimizing testing costs.

How to Create an ALT Plan

How to Create an ALT Plan: Discussion about the basic element necessary to create an accelerated life test (ALT) plan

Fundamentals of ALT

A description of why and how to accomplish ALT, accelerated life testing, to support better decision making in your organization.

Three Approaches to Accelerated Life Testing

In my experience, ALT has three basic approaches: Test to pass, test to failure, and degradation testing. Each fits a specific situation.

Acceleration Factors with Examples

Acceleration factors translate one stress level to another, which is rather useful for accelerated life test interpretation.
