Taking a mass-produced mature product as an example, with a daily production of approximately 500 pcs, the unit cost is 185 RMB, resulting in a total value of 92,500 RMB.
Referring to the sampling principle of GB/T 2828.1-2012 "Procedures for Sampling Inspection by Attributes" (corresponding to the international standard ISO 2859-1:1999),
the Acceptable Quality Limit (AQL) is set at 1% (yield rate ≥ 99%), the Inspection Level (IL) is Level II, meaning the Lot Tolerance Percent Defective (LTPD) is 6.52%.
The sample size is 80 pcs, and the acceptance criterion (Ac) is 2 pcs.
This method increases product cost by only about 0.4%, merely 1/40th of that of tensile testing and metallographic analysis.
