Acceptance Sampling Using Z1.4

Presented on April 25, 2017

Abstract
Acceptance sampling is a common method to determine if the output of a process, the product, should move to the next process or ship to the customer. One common sampling technique is attribute sampling using ANSI/ASQ Z1.4:2003. This presentation explains how to use the standard to determine sampling plans (single, double, and multiple) using an incoming inspection example. The quality engineer needs to understand the binomial distribution, the basis for these sampling plans. This leads to characterizing the risk, described by the operating characteristic (OC) curve. Understanding the OC curve helps determine some distinguished points related to the acceptable and rejectable quality levels (AQL & RQL) and the associated producer’s and consumer’s risk. The standard can help screen rejected lots; the average outgoing quality (AOQ) and average outgoing quality limit (AOQL) describe the plan’s performance.
