Table A Sample Size Code Letters
Table B Single Sampling Plans for Normal Inspection
As default, We use general inspection level II, Acceptable Quality Level (AQL) 0/2.5/4.0 of critical, major, minor defect.
For example, You have a lot of 4,000 units to inspect. According to table 1, "L" is right sample size code for general inspection level II. Therefore in table 2, we pick "200" as L's corresponding sample size. So the allowed maximum number of defective unit is as follows:Critical Defect 0; Major Defect 10; Minor Defect: 14.
In other words, if the number of critical defective units is more than 0, or major defective units is more than 10, or minor defective units is more than 14, the whole lot has to be rejected. It is up to you to make your own decision based on the information and recommendations we have provided to you.
1) Critical defect The "Critical Defect" corresponds to a defect likely to result in unsafe conditions for end-users or specifically requested by customers.
2) Major defect The "Major Defect" corresponds to a defect at the function, or to reduce the usability of the unit of product for its intended purpose.
3) Minor defect The "Minor Defect" corresponds to a defect that is not likely to reduce 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.
