Sample acceptance

Define the reference item, tests, limits, evidence, and decision owner before the sample arrives.

Record reference IDs, material lots, production dates, and shipment identifiers for later investigation.

Require a written change request with impact on cost, timing, tests, and existing inventory.

Use viewing conditions, defect descriptions, and reference photos to reduce subjective disputes.

Record sample ID, expected result, actual result, severity, evidence, and corrective status.

Turn critical drawing dimensions into a repeatable measurement record with units and conditions.

Document the accepted revision, evidence reviewed, open conditions, and authorization for production.

Test the product under stated operating conditions and preserve the observed result.

Label and store the approved reference so production and later inspections use the same item.

Choose a product-specific sampling plan and record lot definition, defect classes, and decision rules.

Verify exact text, identifiers, print position, legibility, and approved artwork revision.

Match a sample's material identity to the specification and the evidence appropriate to the product.

Check the pack hierarchy, protection, labels, and any agreed transit test before signoff.

Use the approved reference and production specification to inspect the actual order before release.

Link the correction to the original failure and check for side effects before approval.

Compare how the sample was made with the intended mass-production process and plan later checks.
