The term "Proof of Testing"

[dvaidr]

I have an assembly made up of sub-assemblies, which costs approx £1.5M to build. Reliability Testing is required as specified by the customer, which includes a failure truncated test. This means that the assembly is destroyed in the process, which is obviously very costly.

Some time ago, I came across 'proof of testing' which could be used as a substitute for this type of test. Unfortunately, I have no further information. Is there an accepted methodology which can be used instead on destroying the assembly?

Highly accelerated life testing (HALT) is an destructive method.

environmental stress screening (ESS) and highly accelerated stress screening (HASS) are non-destructive methods.

I'm aware of HALT etc, but this 'proof of testing' substituted all of this - don't know but the author of the paper was confident that this was going to be adopted more and more by organisations that manufacture high value product.:confused:

Is this term "proof of testing" on a product can give us the asurance that the product is realiable? Just asking....;)

Could you please provide details if this paper?
Thanks.

I do not know the definition of "Proof of Testing" but perhaps it is similar to qualification by similarity (do a gooogle search and you will find such reports in various areas).

I too provide very expensive systems but almost all the testing is performed at the component level. My customers have always accepted qual by sim however they still require testing at the component level including destructive tests.

I use a few components that are built by one supplier but used by several other customers. In this case the supplier tests to the worst case envirironments from each customer and provide a common test report to all customers.
