Statistical Standard
Sampling protocols define the maximum number of defects allowed in a batch for it to be considered satisfactory. Suppliers use the acceptable quality level aql to set the boundary between batch acceptance and rejection during final garment inspection. This limit represents the worst tolerable process average that a buyer will accept as a consistent quality level.
Compliance Logic
Inspection levels determine the sample size pulled from a total production run. Larger batches require more samples to maintain statistical confidence. When the number of identified defects stays at or below the limit, the whole lot passes.
If the count exceeds the threshold, the shipment is rejected or subject to full re-screening.
Operational Tolerance
Risk is shared between the manufacturer and the buyer through these metrics. The producer risks a good batch being rejected, while the buyer risks accepting a bad one. Proper calibration of these levels prevents the delivery of substandard apparel to retail channels.
Inspection Boundary
Limits apply only to random sampling and do not guarantee every single unit is perfect. Critical defects usually have a zero allowance. Minor flaws allow for a higher count because they do not affect the utility of the product.
