Torque Wrench and Torque Screwdriver Calibration

Torque Wrench and Torque Screwdriver Calibration Accredited to ISO/IEC 17025

Torque wrenches are used to control tightening torque in threaded fasteners across manufacturing, mechanical engineering, the automotive industry, aerospace, and maintenance applications. The accuracy of the applied torque is critical for ensuring the safe operation of assemblies, compliance with technical specifications, and the long-term reliability of equipment.

In accordance with ISO/IEC 17025, regular calibration verifies the metrological performance of torque wrenches and ensures full traceability of calibration results to national torque standards.

What We Calibrate

Who This Service Is For

Torque Wrench and Torque Screwdriver Calibration

Torque range: from 0 Nm to 1000 Nm
Measurement uncertainty: 0.5%
Compliance with ISO/IEC 17025 and ISO 6789

Our calibration laboratory performs the calibration of torque measuring instruments in accordance with the requirements of ISO/IEC 17025, including:

FAQ - Torque Wrench and Torque Screwdriver Calibration

Why is it necessary to calibrate torque wrenches and torque screwdrivers?

Calibration verifies the accuracy of the applied torque and ensures that the tool operates within the specified tolerances. Without regular calibration, measurement deviations may occur, leading to damaged threaded connections, product defects, or non-compliance with quality management system requirements.

How often should calibration be performed?

The recommended calibration interval is once every 12 months. For tools used intensively or in critical applications, the calibration interval may be shortened in accordance with the organisation’s internal quality procedures and maintenance requirements.

Which tools do you calibrate?

Mechanical torque wrenches (click-type and ratcheting)
Dial-indicating torque wrenches
Electronic torque wrenches
Torque screwdrivers
Adjustable and preset torque tools
Torque limiters

Which standards are used for calibration?

Calibration is performed in accordance with the requirements of ISO/IEC 17025 and ISO 6789, using certified reference measuring equipment with traceability to national torque measurement standards.

What is checked during calibration?

During calibration, we evaluate:

The actual applied torque value
Deviation from the nominal torque values
Measurement repeatability
Compliance with the specified tolerances across the entire operating range
