Reduce Inspection Costs with Sequential Sampling in ANSI/ASQ Z1.4 2016

Key Topics

• The operating characteristic curve, and the points (AQL, 1-alpha) and (RQL, beta) where the second item is the chance of acceptance. (An ANSI/ASQ Z1.4 plan does not have a specified RQL, but we must determine one based on beta = 0.10, which is tabulated in the standard, so we can create the sequential plan)
• Specification and selection of an ANSI/ASQ Z1.4 sampling plan
• Demonstration that the sequential plan provides comparable protection from poor quality, and in fact identical protection at (RQL, beta)
• Determination and tabulation, in a very convenient format, of a sequential sampling plan
• Application of the ANSI/ASQ Z1.4 switching rules
• Average sample number (ASN), the number of items we expect to have to inspect to decide whether to accept or reject the lot
