Document Summary
Acceptance sampling: a form of inspection applied to lots or batches of items before or after a process, to judge conformance with predetermined standards. May be applied to both attribute and variable inspection. The purpose of acceptance sampling is to decide whether a lot satisfies predetermined standards. Lots that satisfy these standards are passed or accepted. Rejected lots may be subjected to 100 percent inspection. =>in the case of purchased goods, they may be returned for credit or replacement. One random sample is drawn from each lot. Every item in the sample is inspected and classified as (cid:498)good(cid:499) or (cid:498)defective(cid:499) If any sample contains more than a specified number of defectives, c, the lot is rejected. Double-sampling plan: allows the opportunity to take a second sample if the results of the initial sample are inconclusive. Two values are specified for the number of defective items. =>if the number of defectives in the first sample is.
