Now that's an oxymoron if I've ever heard one.
Ummm no.
When dealing with a mechanical component or a item with a limited expected life, a "failure" is when it fails to meet the expectation. However, because it is a wearing or in this case, capacity-reaching item, then it will (by the laws of physics) fail. However, if it reached that expected life expectancy, then it is not a failure even when the mechanical components end up failing (stop working).
What we are dealing with are two slightly different definitions of "fail/failure"
In this case, "fail" is the term for when something is no longer operational. "Failure" is when something does not meet its design life expectancy.
For example: US Mars rover "opportunity" has been operational for over ten years. Mechanically it will eventually fail (stop working), but the mission is a success. On the other hand, China's Jade Rabbit stopped working after about two days... it failed and was a failure (did not meet longevity expectations).

Failure 1b: a state of in ability to perform a normal function.

Fail 1c: to stop functioning normally.
Ridiculous.
Good, you can look up terms... make sure you look up both.
Failure:
1A: omission of occurrence or performance; specifically : a failing to perform a duty or expected action
2A: a falling short or deficiency
If an oil filter is designed for a OCI of 5000m miles and it is on there for 5001 miles before it ruptures, it is not a design failure. Yes, the failed but was not a failure
So this thread title is inaccurate. The filter failed but it was not a filter failure.
