What is mechanical calibration?
Mechanical calibration guarantees the accuracy of technical equipment used to measure mechanical quantities, such as force or pressure.
Differences between calibration and verification
Calibration aims to check the error of a measuring instrument, and sometimes to adjust it to align with a reference standard, ensuring accuracy.
Verification, on the other hand, simply confirms whether the instrument provides readings within acceptable limits established in the applicable Standard.
In other words, calibration measures or adjusts the error, while verification only validates the accuracy of the instrument.
Types of mechanical calibration
There are different types of mechanical calibration methods depending on the instrument or quantities that must be measured. We offer the following types of calibration:
- Mass calibration, mostly to weight instruments.
- Hardness calibration.
- Force and moment calibration.
- Pressure and vacuum calibration
Mass calibration
Our industrial calibration scope for equipment to mass measurement equipment, includes:
Weighing instruments
Weight measuring standards accurately materialise the exact quantity of mass that should be taken into account. The weighing equipment that we use on a daily basis in our everyday environment (commerce, health, trade...) is calibrated and adjusted based on these terms. In our laboratories, we calibrate:

How to calibrate instruments in mechanical calibration?
The first step to accredit mechanical calibration instruments in selecting an accredited calibration laboratory that meets ISO/IEC 17025 requirements, such as Applus+ Laboratories.
The instruments are then sent to the laboratory, where they undergo rigorous testing using traceable reference equipment. Calibration results are compared with recognised standards, and some deviations may be corrected.
Finally, a detailed calibration certificate is issued, which in some cases can confirm that the instrument complies with the established standards.
This process ensures the quality and reliability of measurements, which is crucial to ensure the maximum accuracy of manufacturing, research and similar processes.
