(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.
