To calculate AQL manually, determine the sample size based on the lot size using an AQL table. Inspect the selected samples and count the number of defects. Compare the defect count against acceptance and rejection thresholds defined in the table. If defects are within acceptable limits, the lot passes; otherwise, it fails.

FAQs & Answers

  1. What does AQL stand for? AQL stands for Acceptable Quality Level, which is a statistical measurement used to determine the maximum number of defective items acceptable in a sample batch.
  2. How do you determine the sample size for AQL calculations? The sample size for AQL calculations is determined based on the total lot size using an AQL table, which provides the necessary sample sizes and acceptance numbers.
  3. What happens if the defect count exceeds the acceptance threshold? If the defect count exceeds the acceptance threshold, the lot fails inspection and may be rejected or subjected to further quality assurance measures.
  4. Why is AQL important in quality control? AQL is important in quality control because it helps manufacturers ensure product quality while minimizing inspection costs by allowing a limited number of defects.
