The AIAG P/T is very simple. Mathematically, it is expressed as the following: P/T=(6σe)/(USL-LSL) where USL is the upper specification limit and LSL is the lower specification limit. The measurement standard deviation is multiplied by 6; this gives the "spread" of the measurement error. This "spread" is then … See more One reason we take measurements is to see if our product is within specifications. Consider the following two scenarios: 1. You take a sample from your process and measure it. The result … See more The P/T often comes up as part of a Gage R&R analysis. Suppose we perform a Gage R&R analysis on a measurement system used in our process. We select 3 operators (A, B, and C) to be part of the study. We select five parts that … See more This publication examined two methods for determining the P/T ratio: one from AIAG and one from Dr. Wheeler.
