9. INSPECTION
The C=0 Sampling Plan is used to determine the number of parts that are dimensionally inspected. The sample size is based on the number of parts and the historical level of confidence regarding the part acceptability. Generally, the parts are presented to Inspection in sheet form. Parts are checked in the four corners and in a zig zag pattern throughout the sheet. If one part is rejected, the parts surrounding the scrapped part are checked until we are confident that there are no more out of tolerance parts in the sheet. When parts are given to Inspection as pieces, a sample size is determined using the C=0 Sampling Plan. If one part is rejected, the entire lot is checked. Breaking the parts out of the sheet and packaging for shipment is a critical role of the Inspector. This presents an opportunity to visually inspect the parts and assess cosmetics.
