SOR 648 Accelerated Testing Assumptions
Accelerated Testing Assumptions
Abstract
Chris and Fred discuss accelerated testing. Accelerated testing is great for getting lots of information in a short period of time. You can compress a lot of ‘real-time’ life into a really small amount of testing. But how do you do it right? You need to understand the underlying physics of failure to work out how the compression of time works.

SOR 458 Testing in the Flat Part of the Curve
Testing in the Flat Part of the Bathtub Curve
Abstract
Chris and Fred discuss the question posed to us by one of our listeners regarding the ‘flat’ bottom of the ‘bathtub curve.’ Just a bit of background – the ‘bathtub curve’ represents the hazard rate of a system. That is, it helps us understand the probability that a product that works ‘now’ will fail. The ‘flat’ part of the curve is often cited as the ‘random’ part of the curve where failure is caused by environmental overstress conditions. So how do we test for this part of the curve? … but hang on – is the ‘bathtub curve’ even a thing? Is it even relevant for the useful life of a product? If this intrigues you, listen to this podcast!
