Public Analytical Verification

Build a clear chain of identification

Start with a sample identifier and preserve its connection to the original document. Record the issuer, report number, relevant dates and exact material description. If a document is revised, keep the original and identify which version is being discussed.

A readable archive should make current and earlier records distinguishable without changing what the earlier report actually said. A summary should point back to the original rather than replacing it.

Review scope rather than relying on a badge

NIST’s traceability guidance (opens in a new tab) distinguishes measurement traceability from broad claims about a laboratory or product. Accreditation concerns competence within a defined scope; it is not blanket approval of every product associated with a laboratory.

When a record makes a traceability claim, identify the measurement, reference and supporting chain. A logo, report number or the word verified should not take the place of that explanation.

Understand the reference material

NIST describes different kinds of reference materials (opens in a new tab), with different purposes and assigned values. The name of a reference source alone is therefore not a complete statement of what a result means.

In a review note, preserve the property being measured, its units and any stated limitations. If the report does not address a question, state that limitation rather than filling it with a general quality claim.

Use an archive without overstating it

• Search by exact identity and record number.
• Distinguish the current record from retained historical examples.
• Keep corrections, unresolved differences and missing fields visible.
• Do not represent a template as an issued laboratory report.

The document archive on this website illustrates these organization concepts using fictional records. It contains no real certificates or analytical results.
