Mechanical Calibration

Mechanical calibration is the process of determining and documenting the accuracy of devices and equipment measuring mechanical quantities such as force, torque, and hardness using traceable standards.

This type of calibration plays a critical role in ensuring measurement reliability across a wide range of applications, from production processes to quality control.

Typically, the following devices are calibrated within the scope of mechanical calibration:

• Force gauges (load cells),
• Torque wrenches and torque meters,
• Hardness testing devices (Rockwell, Brinell, Vickers, etc.),

The calibration process is performed using a traceable standard for the relevant quantity. For example:

• Load cells traceable to national force standards are used for force calibration,
• Precision reference torque devices or torque wrenches for torque calibration,
• Hardness standard blocks for hardness calibration.

Typically, the following steps are followed during calibration:

• The device is tested under controlled conditions,
• Readings are taken at specified measurement points,
• The measured values are compared with reference values and deviations are calculated,
• Measurement uncertainty is analyzed and a calibration certificate is issued at the end of the process.

Mechanical calibration guarantees the accuracy of measurements that directly affect both product safety and system performance. This type of calibration is especially vital in automotive, aerospace, defense, construction, and manufacturing sectors.
