ANSI/ASQ Z1.4-2003 (R2018): Sampling Procedures and Tables for Inspection by Attributes is an acceptance sampling system to be used with switching rules on a continuing stream of lots for acceptance quality limit (AQL) specified. It provides tightened, normal, and reduced plans for inspection of attributes are given in Table V-A for each of the single sampling plans for normal inspection and in TableV-B for each of the single sampling plans for tightened inspections. AOQL values are given in Table VI subject to the restrictions of 11.1. Those values will be slightly higher when the limit numbers for reduced inspection are not used under Option 8.5.
Z1.3.1 A sample is a quantity of a tested series of generally unchanged units which is taken from a batch of material to be tested. A sample is used to test the73/23/C.pdf to help you to evaluate the reliability of shipping methods.
ANSI Z1.4 sampling procedures are based on a statistical sampling model.For details on sampling model for the sampling procedures, see the ISO] 1983 standard for continuous prod-uction: 916D Sampling Principles and Practices.1The model that forms the basis for the model and the four-part switching planused in option 8.1 is available in ISO 2859-3. Several modificationsto this standard are described in ISO 2859-10.The full ANSI/ASQ Z1.4 standard is available in the 7211a4ac4a
