Calibrated to NIST means traceability, that was the issue being raised.
The simplest way to assure traceability to NIST is through an accredited lab.
True, it's not just about traceability, but traceability is part of measurement assurance and can't be dismissed.
After all, if you can't trace your measurements then what are you calibrating them to?
