AQL levels are an industry standard tool, and they help to ensure that everybody is on the same page about what the acceptable boundaries for defects are in your production lot. To determine the appropriate AQLs, and what that means in terms of acceptable amounts of defects, you use the AQL chart below.
The columns further to the right are the different AQL levels. With most consumer products, the standard AQL levels are 2.5% for major defects, 4.0% for minor defects, and 0 for critical defects. That’s why we’ve underlined 2.5 and 4.0. Going by this standard, we can see that your inspector will accept a maximum of: 7 major defects, and Level 2 is considered the norm (except for small sample sizes). Level 1 requires only 40 percent of inspection level 2 and can be used where less discrimination is needed. Level 3 equals 160 percent of the amount of inspection level 2. Level 3 will give a lower risk of accepting a lot with excessive number of defects. Acceptable Quality Level - AQL Master tables. INSPECTION LEVEL - General Level II SAMPLING PLAN - Single Normal
NOTE: A sampling plan and an AQL are chosen in accordance with the risk assumed. Use of a value of AQL for a certain defect or group of defects indicates that the sampling plan will accept the great majority of the lots or batches provided the process average level of percent defective (or defects per hundred units) in these

Each ‘AQL table’ is a fundamental tool for preparing a sampling plan for a random product inspection.They give you the number of samples to inspect, and the maximum numbers of defective samples that are allowed. The 2 most common AQL tables. The first AQL table gives you the code letter for sampling.In this example, if the batch to check contains 5,000 pcs, and if you choose level II AQL means “Acceptable Quality Level”, it illustrates the acceptable quality level of products needed.The designed value of defects is expressed as a percentage by the particular sampling procedure.Different AQLs may be designed for different classifications such as Critical, Major and Minor defect. To determine the AQL level of a product you need to use the measure table that is recommended by ISO 2859, NF06-022, DIN 40080, BS 6001, ANSI/ASQC Z1.4. This table allows you to determine the sample size (amount or quantity) that should be taken from an order or batch to be inspected or tested. It then provides you with the values to determine “AQL 2.5 means the buyer considers as acceptable quality limit a defect rate of 2.5% of the total order quantity.” I dont think this is true ;-) If you look at any AQL table, f.e. a Normal Level II single at lets say 15000 pcs order qty it will give you a sample size of 315 with 14/15 defective as limit = approx. 5%.
