Speed and Displacement Verification​

Instron has long been a leader in measuring and verifying speed and displacement and is an active participant in developing the ASTM speed and displacement verification standards. These services ensure that testing parameters are being met and that associated results are being calculated accurately.

Speed and Displacement Verification Standards​

For displacement verification, we can verify your testing instrument to ASTM E2309 or ISO 9513:2012/Cor 1:2013 – Annex H standards, and for speed verification, we can verify to ASTM E2658 standard. ​

Why Do I Need To Verify Speed And Displacement?​

You should calibrate your machine’s displacement measuring system if any of the following apply to you: ​

  • Displacement is critical to your testing needs and is reported in the test results. ​
  • Use of an extensometer is impractical or impossible, and using crosshead displacement is an acceptable alternative.​
  • Crosshead or actuator displacement is used to characterize the displacement of a specimen or component.​
  • LVDTs commonly found in servohydraulic systems are often not linear throughout their range. ​

If any of the following apply to you, then verifying the speed-accuracy of your system is highly recommended:​

  • The material or component under test is strain rate or speed-sensitive.​
  • You are required to report test speed with your results.​
  • Your test method calls for a specific speed.​
  • Even if speed or displacement are not critical parameters, it is a good testing practice to ensure that the speed is constant, stable, and repeatable.​
