Guidance on Uncertainty Budgets for Force Measuring Devices Part 3a. Calculating Uncertainty for Force Measuring Devices for Measurement or Verification of Force Using Non-Linearity

November 21, 2017 12:00:00

What is acceptable for a force calibration uncertainty budget when the device is not calibrated to a known standard and just to a couple manufacturer's specifications. This document aims at helping laboratories calculate force measurement uncertainties for Force Measuring Devices for Measurement or Verification of Force.

Guidance on Uncertainty Budgets for Force Measuring Devices Part 2. Calculating Uncertainty in Accordance with the ASTM E74 Standard

October 27, 2017 12:00:00

The ASTM E74 uncertainty appendix does not align with ILAC Policy for Uncertainty in Calibration ILAC P-14 which can be a problem for any accredited calibration laboratory. The purpose of this post is to combine the ASTM E74 calibration method, ILAC P-14, and JCGM 100:2008 together to help labs calculate measurement uncertainty per point throughout the loading range with the appropriate coverage factor k to meet their accreditation requirements.

This is part 1 of 4 total blog posts. This post deals with why Force Calibration needs a guidance document. The hope is to expand each of these posts and let them stand on there own to a specific force application.

Guest Blog: Know a Torque Wrench Better with this Ultimate Guide

October 10, 2017 12:00:00

A torque wrench is one of the most indispensable tools to have in your toolbox. Before choosing the one perfect for your requirement, you need to be aware of the various types of torque wrenches available, their calibration and factors affecting the calibration. All of these points are essential. Let’s take a look at them

What happens when you overshoot a test point?

September 30, 2017 12:00:00

This blog analyzes the effects of overshooting a test point and the error of doing so. Various calibration laboratories are using hydraulic, screw, and other force calibration machines where it is difficult not to overshoot a test point. By talking about overshooting a test point we are referring to loading past the desired point and then letting the creep in the hydraulic system naturally decrease the force point. Overshooting the force point to 2543 lbf, when the test point is 2500 lbf and waiting several seconds until the reference standard reads 2500 lbf.

The Top 5 costly calibration mistakes for force measurements

September 01, 2017 12:00:00

Not choosing a calibration provider who follows published standards, calculates risk properly, and has open communication with customers about the importance of calibrating the instrument, in the same manner, it is used is critical to lessening measurement risk and ensuring the repeatable results. If these steps are not followed OOT (Out Of tolerance) situations are very probably and these are never cheap. Thus we wrote the top 5 costly calibration mistakes for force measurements.
