AQL Inspection Manual


  1. When using an AQL of 10 and Code Letter A, a solid color arrow will show in the sample size. For Normal and Reduced inspection use Code Letter C. For Tightened inspection use Code Letter D.

  2. When using Double Sampling Reduced inspection. If a * shows for the sample size use the corresponding Single inspection Plan on the front of the AQL Inspector's Rule.

    For MIL-STD-105E or ISO 2859-1 you may alternately use the first doubling sampling plan to the right of the * and arrows. This option was eliminated in the ANSI/ASQ Z1.4-2003 revision.

  3. If the sample size equals or exceeds the lot of batch size do 100% inspection.

  4. Single and Double Reduced Inspection. If the acceptance level has been exceeded, but the rejection level has not been reached, accept the lot but reinstate Normal inspection (ANSI version only).

  5. When Double sampling is to be used, each sample is to be selected over the entire lot or batch.
