Sampling & AQL — SCHEMATIC. Agreed sampling plan. Confirm the scheme → Follow its sequence → Use its criteria.
Schematic illustration. It shows a check path, not actual project evidence or a compliance result.

Read the diagram

  1. Confirm the scheme

    Confirm the applicable sampling scheme before inspection.

  2. Follow its sequence

    Follow the agreed decision sequence; these paths are illustrative.

  3. Use its criteria

    Apply the criteria of that scheme and record the result.

Each sampling plan type has tradeoffs. Single sampling is most common for import QC. Double and multiple plans reduce sample sizes but add complexity. We break down when each approach works best.

Use note

Articles support understanding of quality risk, standards and service routes. Formal requirements depend on the product, target market and technical project confirmation.
