Jedwali la AQL Sampling
Tafuta mipango ya sampuli ya ISO 2859-1. Ingiza ukubwa wa kundi, kiwango cha ukaguzi, na thamani ya AQL ili kupata ukubwa wa sampuli, nambari ya kukubali (Ac), na nambari ya kukataa (Re).
Sampling Plan
Mchakato wa Usampulishaji wa AQL
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 na Kiwango II ni mchanganyiko unaotumika zaidi katika uzalishaji. Inatoa uwiano mzuri kati ya gharama ya ukaguzi na uhakikisho wa ubora.
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.
