(a) The acceptability of a portion of production is determined by comparing the calculated CuSum value with the acceptance limit (“L”) for the specified AQL.

(b) A portion of production is acceptable if the CuSum value, calculated from the subgroup representing that portion, is equal to or less than the acceptance limit (“L”) for all classes of defects.

(c) A portion of production is rejected if the CuSum value, calculated from the subgroup representing that portion, exceeds the acceptance limit (“L”) for one or more classes of defects.
