Note: in quality inspections, the number of defective products is only one of the criteria. ( Note: you can watch this in on Youtube by clicking here.)Д«efore using the AQL tables, you should know three parameters: Getting familiar with the вЂњAQL tablesвЂќ, sometimes called вЂњANSI tablesвЂќ Note that this tool is used mostly during final outgoing inspections (when the products are ready to be shipped out), and sometimes during production (when the number of products is sufficient to have an idea of the batchвЂ™s average quality). Components used in building an airplane are subject to much lower AQL limits.

These proportions vary in function of the product and its market.

4.0% for minor defects (there is some departure from specifications, but most users would not mind it).

2.5% for major defects (these products would usually not be considered acceptable by the end user).

0% for critical defects (totally unacceptable: a user might get harmed, or regulations are not respected).

In practice, three types of defects are often distinguished.

#WHAT IS THE HOW TO#

How to set the limit between acceptability and refusal in a way that can be agreed upon and measured? This is what the AQL comes into play.ДЄs I wrote above, the вЂAQLвЂ™ is the вЂњquality level that is the worst tolerableвЂќ on average over a period covering a number of batches. The buyer needs to control the quality of purchased goods since he does not want too many defects.

Therefore, in many supplier/buyer relationships (particularly when the application does not result in life or death outcomes), the supplier is not expected to deliver defect-free goods. It is often true even after the manufacturer has checked each individual product and has repaired the defective ones since the visual inspection is not 100% reliable. In certain product categories, there will be defective products in virtually every production batch.

#WHAT IS THE ISO#

(This is based on the ISO 2859-1 standard, normal severity, single sampling plans only.) The need for an objective measurement of quality Fill in the calculator to easily find your perfect sample size (the number of pieces that should be randomly checked from the lot being examined) and the number of major and minor defects that can be tolerated based on your AQL specifications. Our calculator is based on the AQL tables but gives you a fast answer. (If youвЂ™d like to see how to use AQL tables, jump to the section вЂњGetting familiar with the AQL tablesвЂќ below.)

Where is the limit between acceptability and refusal, when it comes to defective products?.

How many samples should be picked and inspected, among a batch of product or parts?.

Most suppliers involved in international trade are familiar with it. The вЂњAQL tablesвЂќ are statistical tools at the disposal of buyinspection levelers (for product inspections). Most Asian exporters are familiar with this type of setting.ДЇor example: вЂњAQL is 1.5%вЂќ means вЂњI want no more than 1.5% defective items in the whole order quantity, on average over several production runs with that supplierвЂќ. Importers usually set different AQLs for critical, major, and minor defects. It represents the maximum number of defective units, beyond which a batch is rejected. citizen, Non-U.S.вЂ AQLвЂ stands for вЂ Acceptance Quality LimitвЂ, and is defined as the вЂњ quality level that is the worst tolerableвЂќ in ISO 2859-1.
