Field help (NQA)

Reminder: The Acceptable Quality Level is the quality index of the manufactured products. It requires to pick a certain quantity of samples on a group of finished products, according to the AFNOR NF X06-021 and X06-022 standards. The AQL mathematically guarantees a potential maximum number of defective products defined by a determined units number. The lots of products are rejected if the number of defective parts exceeds the norm.

The AQL is calculated according to two criteria:

• the size of the sample (number of parts from the initial lot associated to the general level of approval), which indicated the sampling code
• the setups for approval and rejection of a lot, i.e. the value of the AQL.

 To determine the AQL, please see the documentation including the calculation tables.

Select the AQL. When entering the sampling, the section "Sample" brings back the size of the rejection and the approval limit according to the quantity entered and the size of the sample.
