>From my experience, we had an in-house test company that ran independently,
we wanted to know the truth, results are not released to the public but used
to improve reliability. The name of the company is at stake. When I see
something like a cell phone company that has battery fires I know it's
either a mickey mouse company, or someone did not do their job properly!
There is nothing to be gained by "fudging" results....
component failure should follow a "bath tub" shape, on a graph of
failure rate on the vertical axis and time on the horizontal. The shape can
tell a lot about product quality, you are testing many samples, and they
should lie on the same curve. Bad production methods or bad component
quality can be indicated by a spread in different ways. We also tested
components like the SCR's used in the same manner, we ran 70A SCR's at over
1000 amps, tested many samples for months like that, also tested spade
terminals used in the products.
