sampling plan based on ANSI/ASQC Z1.4 multi level acceptance
SummaryHow to define a sampling plan based on ANSI/ASQC Z1.4 to allows a mix a critical, major and minor defects
It seems to me that it's a common practice to define rules as follow :
Exampe Order size: 40,000 pcs of memory sticks, to be made in 1 batch by the supplier.
Single sampling plan.
Normal severity, level II.
AQLs: critical 0, major 1.5%, minor 4.0%
Aka we will accept the lot if for the sample size we have 0 critical, less than 1.5% of major defect and less than 4% of minor defect...
Now the way our solution is defined, we assign an inspection level (and only one) at an inspection plan...so how to achieve requirement previously defined ?
