Tablica AQL uzorkovanja
Pretražite planove uzorkovanja ISO 2859-1. Unesite veličinu serije, nivo inspekcije i vrijednost AQL da biste dobili veličinu uzorka, broj prihvatanja (Ac) i broj odbijanja (Re).
Sampling Plan
Proces AQL uzorkovanja
1. Determine lot size → 2. Select inspection level (default: II) → 3. Find sample size code letter → 4. Look up Ac/Re numbers for your AQL value → 5. Inspect the sample → 6. If defectives ≤ Ac → Accept lot. If defectives ≥ Re → Reject lot.
Rule of thumb: AQL 2.5 sa Nivoom II je najčešće korišćena kombinacija u proizvodnji. Pruža dobar balans između troška inspekcije i osiguranja kvaliteta.
Levels vs. severity: The inspection level (S-1…S-4, I, II, III) only selects the sample size code letter. Normal, tightened and reduced inspection are a separate concept — inspection severities applied through the switching rules of ISO 2859-1 (clause 9) based on recent lot acceptance history. This calculator gives single sampling plans for normal inspection (Table 2-A); the inspection level stays unchanged when severity switches.
