Example 1 - Single Sampling

Q 

Normal inspection is in use, the batch size is 1000, AQL is 1.5, single inspection and the inspection level is II. What is the sampling plan?

A 

1. Set the batch size (501 to 1200) in the upper window

2. Look next to the Inspection Level II to find the Code Letter of J.

3. Next set the AQL window to 1.5,

4. Looking under Code Letter J in Normal Inspection we find a sample size of 80, an acceptance number of 3 and a rejection number of 4.

5. If the defect count is 3 or less accept the batch.

6. If the defect count is 4 or more reject the batch.
