What it certifies
Technical competence of a testing or calibration laboratory, and the traceability of its measurements.

Typically required for
Test houses, calibration labs, in-house metrology.
These are claims published by the suppliers themselves. We have not seen the certificates. Always ask for a current certificate and its scope before placing work.
