Abstract : There are several oil-water separator systems currently being developed for possible future use aboard Navy ships, In order to be accepted, these systems must meet certain specified requirements: In Port -- 20 ppm of oil or less in effluent water at least 95% of the time; and At Sea -- 100 ppm of oil or less in effluent water at least 99% of the time. In order to determine whether a system meets the threshold requirements given above, a binomial acceptance sampling plan is often used. In this type of plan, a specified number of effluent samples are collected and analyzed. Each sample is then classified as either a success (oil content does not exceed threshold) or a failure (oil content exceeds threshold). If the number of failures is not greater than some prespecified number, c, the system is accepted. If the number of failures exceeds c the system is rejected.
