01Give each field its proper role

A manufacturer specification describes a stated requirement or target for a material. A laboratory result describes an observation reported for a tested sample. A verdict compares a result with criteria under the report’s stated decision process.

A report may reproduce project specifications without identifying who originally set them. In that case, call them the report’s stated criteria rather than inventing a manufacturer or regulatory origin.

The supplied TB-500 5 mg report provides a concrete reading example. It identifies lot PEP-06-SQQ, lists a 5 mg label claim and places results, specifications, methods and verdicts in separate columns.Supplied TB-500 5 mg report — MA-PEP-0006 revision 01 (opens in a new tab)

This article uses the document to demonstrate attribution. It does not independently confirm the measurements or authenticate the laboratory, signatures or material.

02Compare the values without replacing them

The 99.00% figure is the listed minimum, while 99.43% is the reported area-percentage result. Writing that the laboratory “measured 99.00%” would substitute a criterion for the observation.

Likewise, the 5 mg label claim is distinct from the reported 4.99 mg per vial. Rounding the reported value may be appropriate in some contexts, but a transcription should retain the supplied number and make any later rounding explicit.

The water-content limit of 8.00% does not mean that the sample contained 8.00% water. The document reports 4.55%. A pass verdict cannot replace either value when the reader needs to understand the quantitative result.

03Keep the result tied to its evidence

A value from one identified report should not become a universal result for every product or lot bearing the same name. If a product page presents a general specification, distinguish it from a particular certificate’s measurements.

Preserve the analytical basis as well as the number. The example’s purity field is labelled area percentage; it should not be rewritten as a mass fraction or used to calculate active content without separate justification.

Where a result and a specification appear inconsistent, inspect the units, basis, rounding and decision-rule notes before drawing a conclusion. Record unresolved discrepancies rather than quietly changing one field to make the comparison look tidy.

04Use explicit wording in summaries

A clear sentence can say that “the supplied report gives a purity result of 99.43% by area against a stated minimum of 99.00%”. This preserves the document’s roles without claiming a new measurement.

For a specification-only source, say that the supplier specifies a requirement and avoid adding “tested” or “confirmed” unless there is evidence of the relevant test. For a result-only source, do not invent an acceptance range.

Review charts, product tables and comparison pages for the same distinction. A column headed “purity” may need a more specific heading if it mixes minima from some sources with measured values from others.

The editorial goal is simple: a reader should know whether a number says what was required, what was declared or what was reported as observed. Those meanings should remain visible wherever the number is reused.
