Abstract

This Uganda Standard provides double sampling plans by attributes for the acceptance inspection of lots of discrete items. The plans are indexed by the producer`s risk quality (PRQ) and the consumer`s risk quality (CRQ) where the nominal producer`s and consumer`s risks are respectively either (5 %, 5 %), (5 %, 10 %) or (10 %, 10 %). Plans are provided for inspection for percent nonconforming and for inspection for nonconformities per 100 items. The lot is accepted if there are no nonconforming items (nonconformities) in the first random sample, and rejected if it contains two or more nonconforming items (nonconformities). If precisely one nonconforming item is found in the first sample, a second random sample is drawn; the lot is then accepted if the second sample contains no nonconforming items (nonconformities) and rejected otherwise.
