ISO 2859 series provides sampling schemes for inspection by attributes. ISO 2859-1 focuses on lot-by-lot inspection with acceptance quality limit (AQL). ISO 2859-2 covers individual lot sampling plans. ISO 2859-3 provides reduced sampling procedures. ISO 2859-4 addresses quality level assessment procedures
SPC monitors and controls production process quality using statistical methods. Ensures efficient operation with less waste and scrap. Can be applied to any process where conforming product output can be measured
Cp measures process capability as number of times spread fits into tolerance width. Cm indicates machine capability as number of times spread fits into tolerance width. Cpk corrects process capability for position, should be at least 1.33. Cmk corrects machine capability for position, should be at least 1.67
