What is AQL?

 Introduction

AQL is widely used for the number of defects allowed in a batch of goods, but it is acceptable in terms of the overall quality of the goods.
Details
Acceptable Quality Limit (AQL) is a standard used by professional inspectors when conducting sampling inspections, following the ISO 2859 standard and the tables it provides. This document is published by ISO and is equivalent to all national regulations (ANSI/ASQC Z1.4, NF06-022, BS 6001,) and is an international standard.

Professional third-party inspectors use the AQL table to determine the correct sample size (in short, how many samples are selected and inspected from the production batch) and the acceptance level (how many samples may be defective). Based on the AQL table, the inspector will sample the goods to evaluate different characteristics. If the number of defectives exceeds the AQL, the inspection report will show that the product did not reach the AQL level.

At Nanjing Weproving Inspection, we strictly follow the ANSI ASQ Z1.4 standard for sample testing.

Necessity of random sampling:

Whether it is a brand, online store or quality control professional, it is necessary to evaluate the quality of the product before shipment. If your goods are high-priced, high-risk, or your order quantity is small, you may need a fully inspection service.

Benefits of AQL and random sampling:

1.Save time
2.Save cost
3.Set clear criteria
4.Give the flexibility 
5.Ease the communication of quality expectations
