A technically sound laboratory result still concerns an identified specimen. The relationship between that specimen and the proposed production needs its own clear record.
ASQ's quality-plan guidance connects requirements with planned activities, responsibilities and evidence. ASQ — quality plans.
Preserve the selection history
For a material evaluation, identify who selected the specimen and which material or production condition it represents. Do not describe a convenient development swatch as though its relationship to later supply were already established.
State the conclusion carefully
Keep the laboratory's tested scope and the selection boundary distinguishable. If production changes, review whether the existing evidence remains relevant. The report and the product population need a justified link rather than a shared colour name.
