Some test labs offer tests and/or adjustments that give the same tests as

Then you have no way of knowing whether their work is accurate.

For those where traceability is not important but cost is, it's a very
viable option.

But is isn't calibration, because there is no traceability to an
accepted standard.

At the end of the day, you know where you stand, but just don't have the
certificate to prove it

You don't know where you stand, because the work is not traceable.
