NCSLI Force Course

Thank you for attending the Force Calibration & Beyond: Better Measurements Safer World tutorial.

Anyone making force measurements should attend this course if they are not familiar with all of the sources of measurement error regarding force measurements. Examples of these errors include proper calibration adapters. Using a top block for compression loading can produce up to a 0.5 % error if the end-user uses something with a different hardness and/or flatness.

Using the wrong pin size on a tension link can cause a 2 % error on a device with an accuracy of 0.1 % of full scale. The measurement errors demonstrated and discussed will include errors associated with improper alignment, use of different and/or incorrect adapter types, thread depth and thread loading, and some load cell troubleshooting techniques. During the workshop, we will discuss over twenty common major error sources and how to avoid them.

We will then focus on ISO/IEC 17025:2017 section 6.4.5 “The equipment used for measurement shall be capable of achieving the measurement accuracy and/or measurement uncertainty required to provide a valid result.” Taking this section into account, we will discuss measurement decision risk with a focus on NCSLI/ANSI Z540.3 Method 5 & Method 6 and how the Test Uncertainty Ratio (TUR) impacts the laboratories ability to make statements of conformity to a specification per section 7.1.3 of the ISO/IEC 17025:2017 standard.

Recommended skill level for the course is anyone who has experience with force equipment and wants to learn how they can minimize potential measurement errors and reduce their measurement risk.

NCSLI Force Course Learning Objectives

  1. Identify and Quantify force measurement errors.
