AQL

What does AQL mean?

AQL is the acronym for Acceptable Quality Limit (or Level). This represents a statistical measurement of the maximum number and range of defects that is considered acceptable during a random sampling inspection of your goods.

Defects found during a standard random inspection are sometimes classified into three levels: critical, major and minor.

The AQL inspection is only a report on the findings at the time of the inspection. You can make a final decision in consultation with your supplier after reviewing the inspection report.

TYPES OF DEFECTS AND DEFECTIVES 

Defects and defectives are defined into three classes as follows .

Critical

A critical defect is one that judgement and experience indicate is likely to result in hazardous or unsafe conditions for individuals using, maintaining or depending upon the product, or may have legal implications. A critical defective is a unit of product that contains one or more critical defects and may contain major and/or minor defects. 

Major

A major defect is one, other than critical, that is likely to result in failure, or to reduce materially the usability of  the unit of product for its intended purpose or to cause the customer such dissatisfaction that the unit of product will most likely be returned.

A major defective is a unit of product that contains one or more major defects, and also may contain minor defects but contains no critical defects.

Minor

A minor defect is one that is not likely to reduce materially the usability of the unit of product for its intended purpose or is a departure from established standards having little bearing on the effective use or operation of the unit.

A minor defective is a unit of product that contains one or more minor defects but contains no critical or major defects.

Sampling for inspection follows ISO-2859-1, General Inspection Level II, Normal Inspection, Single Sampling.

TYPES OF INSPECTION RESULTS:

Inspection results are defined into Four classes as follows. Shipment releasing is based on inspection results.

Passed

Passed denotes that the inspected batch had been produced to our minimum requirement by the supplier at the time of inspection. Supplier can contact our Logistic Department for shipment arrangement.

Failed

Failed denotes that the inspected batch does not meet our minimum requirement at the time of inspection. Corrective action and follow up inspection must be taken until the batch has a “Passed” result before shipment.

Released

Released might not denote that the inspection result is acceptable, it might be failed an issued has been settled, inspection certificate would then also be released.

Missed

Missed denotes that the inspection cannot carry out completely, or leads extra work due to supplier’s issue, or the supplier failed to meet requirements stated in this document. The supplier is required to pay for the inspection charge and rectifies issue before next inspection.
