The article discusses the differences between ISO 376 and ASTM E74 in hopes to prevent intermixing of the standard as we had heard of companies using an ASTM E74 calibration to certify a tensile machine to ISO 7500.

Morehouse ISO 376 Calibration Certificates

February 20, 2018 12:00:00

Morehouse has been performing ISO 376 calibrations for over the last fifteen years. In this time frame, we have changed our ISO 376 certificate format three times. The latest change offers additional information such as calibration graph per run and is laid out in a way that is much more cohesive making it easier to read and understand

Calibrating Multi-Axis Load cells in a Morehouse Calibrating Machine

Finally, a way to reduce excessive clutter and simplify tensile calibrations for Load Cells, Crane Scales, Tension Links, and Dynamometers.

Choosing the Right Indicator for your Load Cell System

December 19, 2017 12:00:00

If you get everything else correct and choose the wrong indicator, the overall system performance can suffer. This blog is going to better detail three specific indicator types. These are: 1- An A/D indicator that requires a computer to read the display 2- A battery powered portable indicator with minimal span points 3- A versatile indicator that can be used with several span points or accurately display mV/V through calibration.

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.

Guidance on Uncertainty Budgets for Force Measuring Devices Part 1. Why Do We Need a Guidance Document?

October 13, 2017 12:00:00

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.
