Mechanisms

• Acceptance Sampling Plan
  • The plan sets a sample size and an acceptance number (max defectives to still accept) derived from lot size and a target quality level, so the plan's operating characteristic — its probability of accepting lots of each true quality — is chosen, not accidental.

    This sourceDefines an acceptance-sampling plan by its sample size, acceptance number, quality-level selection, and resulting operating-characteristic curve.

• Quality Acceptance Test
  • So under a contract agreed months earlier, the two parties committed to an acceptance sampling plan tied to a stated Acceptance Quality Limit: pull a random sample of 200

    This sourceProvides an attribute-sampling table entry with a 200-unit sample and accept-two/reject-three thresholds.

Verification

Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.

Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
