What this topic covers
Why a measurement result is not meaningful until it is compared with an approved requirement.
Core testing ideas
Acceptance criteria define what result is conforming, nonconforming or subject to further review.
Criteria can come from drawings, contracts, standards, engineering specifications or regulatory requirements.
This site does not invent engineering acceptance limits.
Measurement and method limits
A result is only meaningful when the characteristic, units, method and acceptance requirement are clear.
Evidence and traceability
Traceability and documentation let later reviewers understand what was tested and with which equipment and method.
Using the result
Inspection plans should focus effort on meaningful characteristics instead of collecting data without a decision path.
