7. DEFECT CLASSIFICATION & FINAL JUDGMENT
7.1 AQL Sampling Plan & Quantified Defect Threshold (Fixed For Direct Execution)
- Applicable AQL Standard: ANSI/ASQ Z1.4-2018, General Inspection Level II, Normal Single Sampling Plan, Non-Tightened Inspection for USA Export Cabinet Goods Fixed AQL Threshold: Critical Defect (CR) = 0 AQL; Major Defect (MA) = 2.5 AQL; Minor Defect (MI) = 4.0 AQL
- Sampling Quantity Rule (100% Executable) 1. Lot Size 1–50pcs: Sample Size = 13pcs 2. Lot Size 51–150pcs: Sample Size = 20pcs 3. Lot Size 151–280pcs: Sample Size = 32pcs 4. Lot Size 281–500pcs: Sample Size = 50pcs 5. Lot Size 501–1200pcs: Sample Size = 80pcs Accept/Reject Criteria: CR=0 Allowable; MA ≤ Acceptance Number / ≥ Rejection Number; MI ≤ Acceptance Number / ≥ Rejection Number
- Quantified Defect Classification & Judgment Threshold1. Critical Defect (CR) – 0 Tolerance, 100% Reject Once Found – Formaldehyde emission exceeds CARB P2/TSCA Title VI limit (>0.05ppm) – Structural crack, loose carcass, complete functional failure affecting installation – Hazardous sharp edge/point violating US safety standard – Wrong material grade, non-compliant board failing US entry regulation – Water leakage & severe moisture damage for bathroom cabinets 2. Major Defect (MA – AQL 2.5) – Dimension tolerance over ±1.5mm, diagonal error over 2mm – Obvious finish defect: blister, delamination, obvious color difference under natural light – Hardware malfunction: hinge/slide jamming, no soft-close function, abnormal noise – Loose joint, panel warpage >2mm, uneven assembly gap >1mm – Waterproof failure of bathroom cabinet base structure 3. Minor Defect (MI – AQL 4.0) – Tiny invisible scratch/faint stain, no impact on appearance & sales – Slight uneven gap ≤1mm, no visual misalignment – Minor surface sanding mark, no damage to finish integrity – Slight hardware tightness deviation without functional impact
- AQL ACCEPTANCE & REJECTION VALUE LOOKUP TABLE (ANSI/ASQ Z1.4-2018, GENERAL LEVEL II, NORMAL INSPECTION)Applicable for Thailand & Cambodia USA export cabinet inspection, fixed CR=0, MA=2.5, MI=4.0
| Lot Size Range | Sample Size | Critical (CR=0) Accept/Reject | Major (AQL2.5) Accept/Reject | Minor (AQL4.0) Accept/Reject |
|---|---|---|---|---|
| 1 – 50 PCS | 13 | 0 / 1 | 1 / 2 | 2 / 3 |
| 51 – 150 PCS | 20 | 0 / 1 | 1 / 2 | 3 / 4 |
| 151 – 280 PCS | 32 | 0 / 1 | 2 / 3 | 5 / 6 |
| 281 – 500 PCS | 50 | 0 / 1 | 3 / 4 | 7 / 8 |
| 501 – 1200 PCS | 80 | 0 / 1 | 5 / 6 | 10 / 11 |
Table Instruction: Accept = Max allowable defects; Reject = Shipment fail if defect quantity reaches this number. Zero tolerance for all Critical defects, any CR defect leads to direct rejection.
