What is EN ISO 6789-2021?

EN ISO 6789-2021 is a standard that defines the requirements and test methods for hand-operated torque tools. It specifies the performance, accuracy, and calibration procedures for torque wrenches, screwdrivers, and other hand tools used for tightening or loosening fasteners.

The Importance of EN ISO 6789-2021

Adhering to EN ISO 6789-2021 is crucial in industries where precision and accuracy are essential. When torque tools are used incorrectly or produce inconsistent results, it can lead to mechanical failures, safety hazards, and product quality issues. This standard ensures that torque tools are properly calibrated and provide reliable results, reducing the risk of errors and failures.

Key Requirements and Test Methods

EN ISO 6789-2021 specifies various requirements for torque tools, including calibration procedures, performance levels, and measurement units. It defines different classes of accuracy, ensuring that manufacturers produce tools suitable for specific applications. The standard also covers various test methods for evaluating the performance of torque tools, including tests for repeatability, durability, and operational safety.

Benefits for Users and Manufacturers

By following EN ISO 6789-2021, users of torque tools can have confidence in the accuracy and reliability of their equipment. This standard allows for consistent and precise tightening or loosening of fasteners, preventing under-tightening or over-tightening that could compromise the integrity of assemblies. For manufacturers, complying with this standard helps build trust and reputation amongst customers, as it demonstrates a commitment to providing high-quality tools that meet industry standards.
