AQL Inspection
An AQL inspection is the physical product-checking process where inspectors examine selected items, record visible or functional defects, take notes or photos, and prepare a pass-or-fail report for the batch.
Product Sample Selection
AQL inspection begins by selecting a sample from the full production lot. The sample size depends on lot size, inspection level, and the chosen AQL value, so inspectors check enough units to judge batch quality without reviewing every item.Defect Count Review
Inspectors examine each selected product and record defects found in the sample. These defects are counted by type and seriousness, then compared with the acceptance number allowed under the selected AQL standard.Critical Defects
Critical defects are the most serious inspection failures because they can affect product safety, legal compliance, or normal use. Even one critical defect may cause the batch to fail, depending on the buyer’s inspection rules and product category.Major Defects
Major defects can affect product function, appearance, performance, or customer acceptance. A batch may still pass if major defects stay within the allowed limit, but it can fail when the defect count crosses the acceptance number.Minor Defects
Minor defects are smaller quality issues that usually do not affect product use. They may include light marks, small finishing issues, or slight appearance problems, but they are still counted during inspection and must stay within the allowed limit.Acceptance Number
The acceptance number shows how many defects are allowed in the sample before the batch fails. If the defect count is equal to or below this number, the lot can pass. If it goes above the limit, the lot fails.Rejection Number
The rejection number shows when the batch should be rejected based on sample defects. Once defects reach the rejection number, the inspection result shows that the batch quality is not acceptable under the selected AQL level.Inspection Report
After checking the sample, inspectors prepare a report with lot size, sample size, defect types, defect counts, photos, test notes, and pass or fail results. This report helps buyers decide whether to accept, rework, or reject the shipment.Shipment Decision
AQL inspection supports shipment decisions before goods leave the factory. If sample defects remain within the allowed limit, the batch can move forward. If the defect count is too high, the shipment may need sorting, repair, reinspection, or rejection.To understand the full form, basic meaning, and overall role of AQL in product inspection, read the main guide on AQL full form.
