This is illustrative template content, not a statement about METRILAB’s accreditation status.

Traceability concerns measurement results

Metrological traceability relates a result to a reference through a documented, unbroken chain of calibrations, each contributing to measurement uncertainty. A statement that an instrument is “traceable” needs supporting evidence.

Accreditation adds independent assessment

Accreditation assesses a laboratory against a specified standard and defined scope. Confirm the current scope for the requested measurement, range and service location rather than relying on a logo.

Ask a precise question

Request confirmation of the reporting basis, measurement uncertainty and scope coverage for your actual instrument. Neither label on its own establishes that the result will meet your intended acceptance criteria.
