The AQL system according to DIN 40 080 can be simulated using the random sample simulator. In a total population of n=1000 balls, 0.5%, 1%, 2%, 5%, 10% and 20% of the balls are of different colours. This symbolizes the quantity of “bad” parts. Only the appropriate colour is considered and evaluated, depending on the AQL value assumed. A random sample of n=100 can be taken and evaluated by simply tilting the simulator. The balls roll in ten channels. The random sample is thus shown clearly and the evaluation is simplified. Smaller random samples can also be simulated by evaluating only one part of the channel.
