An acceptable quality level is a test and/or inspection standard that prescribes the range of the number of defective components that is considered acceptable when random sampling those components during an inspection. The defects found during an electronic or electrical test, or during a physical (mechanical) inspection, are sometimes ...
A single sampling plan for attributes is a statistical method by which the lot is accepted or rejected on the basis of one sample. [4] Suppose that we have a lot of sizes M {\displaystyle M} ; a random sample of size N < M {\displaystyle N<M} is selected from the lot; and an acceptance number B {\displaystyle B} is determined.
MIL-STD-105 D Quick reference Table, TABLE I and TABLE IIA. MIL-STD-105 was a United States defense standard that provided procedures and tables for sampling by attributes based on Walter A. Shewhart, Harry Romig, and Harold F. Dodge sampling inspection theories and mathematical formulas.
A variables sampling plan can be designed so that the OC curve passes through two points (AQL,) and (LQL,). AQL and LQL are the Acceptable quality limit and the limiting quality level respectively. α {\displaystyle \alpha } and β {\displaystyle \beta } are the producer and consumer's risks.
