Mil. Std. 105E offers three types of sampling plans: single, double and multiple plans. The choice is, in general, up to the inspectors.

How do you use sampling plan in a table?

4 Steps to determining your sample size and defect tolerance using the AQL table

1. Choose your inspection type and inspection level. Your inspection type will be either “general” or “special” shown in the two columns on the first part of the table.
2. Determine accept and reject points and sample size based on your AQL.

How do you use military standard sampling?

How Does the Standard Work?

1. First you determine the lot size.
2. Then you determine the inspection level.
3. Then you review the table(s) in Mil Std 105e.
4. The table provides your sample size and accept and reject criteria.
5. You then select your sample from the lot.
6. Inspect the parts.

How do you determine an acceptable quality level?

Acceptable quality level (AQL): AQL is typically considered to be the worst quality level that is still considered satisfactory. It is the maximum percent defective that can be considered satisfactory. The probability of accepting an AQL lot should be high. A probability of 0.95 translates to a risk of 0.05.

What does C 0 sampling plan mean?

C=0 sampling plans are based on the premise of accepting the lot if zero defects are found during the inspection, and rejecting the lot if one or more defects are found during the inspection.
