Why a 4:1 TUR is not enough:
The importance of analyzing the probability of false accept risk

Several organizations and publications reference or insist on maintaining a 4:1 Test Uncertainty Ratio (TUR) without understanding the level of risk that they may be subjecting themselves to. The general thought is if the lab performing the calibrations has standards at least four times better then what they are calibrating that everything is good. This webinar discusses TUR, PFA Risk, and why the location of the measurement matters. We will discuss two managed risk guard banding methods (5 & 6) found in the ANSI/NCSL Z540.3 Handbook. We will show that a 4:1 TUR is not enough and can result in a 50 % risk. This webinar is intended for anyone thinking a 4:1 TUR or TAR is enough as we will prove that thought process to be somewhat flawed. Others wanting to know more about risk should also attend.

Learning Objectives:

*The webinar attendee will understand that a 4:1 TUR & 4:1 TAR is not enough when analyzing risk

*The webinar attendee will learn more about the role measurement uncertainty makes in making statements of conformance

*The webinar attendee will know the importance of the location of the measurement and leave with a basic understanding of guard banding
