Environmental or Reliability Testing
Abstract
Adam and Fred discussing the different types and intents of reliability and environmental testing
Key Points
Join Adam and Fred as they discuss the different types and intents of reliability and environmental testing
Topics include:
- How does reliability testing differ from environmental or standards testing?
- The importance of keeping the “Intent” of the test front and center at all times
- Being aware that similar testing methods can have very different purposes.
Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques, to field data analysis approaches.

Hi fred,
Thank you very much for your talking,
I have one question hope you can explaint:
Exp: In the Reliability testing, I do the Hight temp test. In the environmental test, I also perform the high temp test. So, what is the diffirence ?? Do I need perform both of those test??
Tks.

Good question Trinh, if applying the same stress it really doesn’t matter what you call the test (environmental or reliability) either way you need to know what you are trying to achieve. If the objective is to determine functionality when operating at a high temperature, we often call that an environmental test. If the objective is to determine how high a temperature the unit will continue to operate, that may be a step stress test or a HALT. If the objective is to accelerate a failure mechanism using high temperature, then it’s an ALT or a test to estimate to time to failure. All three could be done in a high-temperature chamber.
For any test or experiment start with the hypothesis or objecive – be very cleaer on what you expect to learn from the test, otherwise the results my not all that useful.
Cheers,
Fred
