You receive 7500 frames from your supplier every week. You sample to General Inspection Level II and use AQL = 1.0 This supplier has been very good and you have accepted all of the last ten lots. As a result, you are on reduced inspection What is your sampling plan for the next delivery? n = c =
Solution:
n= sample size = 200 according to AQL sampling chart General Inspection level 2 for a lot size of 7500.
c= 5 is the defect acceptence number.
our lot size of 7500 is under the lot size range of (3201 to 10000) as shown in above table, this corresponds to letter 'L' since our inspection level is ll.
Therefore, letter L corresponds to sample size of 200 and acceptance number of 5 because our acceptance quality level is 1.0
