Example of Using Acceptance Tables

Determining Sample Size and Acceptance Levels

  • The discussion begins with an example of using acceptance tables to determine sample size and acceptance/rejection levels for a lot of 1,100 t-shirts. This is the first step in the process.
  • The size of the lot (1,100 pieces) falls within the range of 501 to 1,200 pieces as indicated in Table K. This identification is crucial for further steps.

Cross-referencing Inspection Level with Lot Size

  • The next step involves cross-referencing the inspection level against the lot size to obtain a corresponding letter. For this example, General Inspection Level 2 results in letter 'J'. This letter will be referenced later in Table L.

Consulting Table L for Sample Size

  • It is essential to consult Table L, which serves as a master data source for normal dispersion. Here, we locate the letter obtained previously ('J') to visualize the required sample size for verification.
  • Based on letter 'J', it is determined that a sample size of 80 t-shirts must be verified from the lot during inspection. Understanding this requirement is critical for quality control processes.
