Meaning of Identifiers
HALT (Highly Accelerated Life Test). There is an opinion that “its name doesn’t do it justice”.
In the first Part “Is the HALT a Life Test or not?” we added the test time to the HALT stress set. We see there is the Life in HALT.
In Part 2 we added knowledge of the lifetime distribution type and a shape parameter (variation). We were able to evaluate the reliability during the warranty time with a given CL by “pulling the lifetime distribution by the tail”. We see HALT may be a quantitative Test.
If we know the effect of stress on the lifetime then we can Accelerate the test.
If we know the effect of multiple stresses on the lifetime, we can Highly Accelerate the test.
The puzzle is complete. I like the name HALT (Highly Accelerated Life Test).
Oleg Ivanov is an aircraft engine design engineer with experience creating accelerated tests of aviation products (auxiliary power units, turbo generators, turbopumps, electro pumps). I see the shortcomings of standards and theory reliability/lifetime tests. My passion is to create new approaches (methods, tools) to accelerated tests. Life Cycle Simulator is one of these new tools.
