4 Factors Playing a Significant Role in The Calibration of Universal Testing Machine

Universal Testing Machine

A universal testing machine is helpful to check both the compressive and tensile strength of varied materials. We have usually heard of tensometers; they are also recognized as tensile testing machines. Since new functionalities have been added to the machine and it has become more versatile, it is called universal. Certainly, a universal testing machine can perform both compression and tensile tests on different structures, components, and materials.

Why is the calibration of a Universal testing machine needed?

The purpose behind the calibration of a universal testing machine is to lower down the number of uncertainties that may end up occurring in the test results. Machines like universal testing are usually put into use during the quality check phase. Many big factories utilize these machines to make sure about the quality of the properties used in the materials. These machines perform the most crucial step of the QA test before the final distribution of the materials.

Significant factors that need to be considered

Various factors need to be considered for the calibration of the Universal testing machine.

  • For this process, one needs to confirm the authenticity of the universal testing machine instruments.
  • One also has to determine if calibration is needed in the compression or tension.
  • It is also required to measure, inspect and calibrate the force and displacement.
  • The determination of the Lachine load size is also required, and one also has to decide if extensometer calibration is required or not.

How can calibrations be performed?

Fortunately, there have been standards developed by the industry for the performance of the calibration. The standards that can be performed all over the world are given by ASTM International. Almost all the organizations operating in different parts of the world adopt these standards.

The ASTM international provided standards make sure that the testing of the UTMs and all related pieces of equipment will remain the same irrespective of who executes the calibration.

The standards clear out where should the connection points be located and the direction in which the force should be applied. Moreover, to attain authenticity, it demands two readings.

Advisable calibration’s frequency

Once the certificates and the accreditation expire, the universal testing machines need to get the calibrations done. Usually, the accredited certificate of calibration expires after the completion of one year.

Many collaborated partners recommend that the types of equipment that are being utilized in the materials testing need to get calibration after at least every 12 months.

However, certain conditions require the execution of calibration on the universal testing machines. Several industries may require more frequent calibration of the equipment. Furthermore, when the equipment is being moved, certain industry standards require the equipment to be recalibrated.

Who can execute the calibration?

The accredited calibration partners and the technicians utilize the Electromechanical universal testing machines that further uses the electromechanical load frames.

These come along with pre-programmed test pilot software. This software is commendably useful in the production of authentic test results. It is immensely user-friendly and can be easily used by beginners with no problem at all.
