Comprehensive Guide to ISO 6789 Calibration of Torque Wrenches and Measuring Tools Laboratory Testing Service

ISO 6789 is a global standard that governs the calibration of torque wrenches and measuring tools. The standard provides requirements for the design, testing, and evaluation of torque wrenches and measuring instruments to ensure their accuracy and reliability.

The legal and regulatory framework surrounding ISO 6789 calibration is established by various international and national standards organizations. Some of the key standards include:

  • ISO 6789-1:2013 (Calibration of torque wrenches - Part 1: Requirements for the calibration of torque wrenches)

  • ISO 6789-2:2013 (Calibration of torque wrenches - Part 2: Requirements for the calibration of measuring instruments)

  • ASTM F2436-10 (Standard practice for calibration of torque wrenches and measuring instruments)

  • EN ISO 6789-1:2013 (Calibration of torque wrenches - Part 1: Requirements for the calibration of torque wrenches)

  • TSE ISO 6789-2:2013 (Calibration of torque wrenches - Part 2: Requirements for the calibration of measuring instruments)

    • These standards outline the procedures and requirements for the calibration of torque wrenches and measuring tools, including the use of specialized equipment and testing facilities. The international and national standards organizations responsible for developing these standards include:

  • International Organization for Standardization (ISO)

  • American Society for Testing and Materials (ASTM)

  • European Committee for Standardization (CEN)

  • Turkish Standards Institution (TSE)

    • The standard development process involves a collaborative effort between industry experts, regulatory bodies, and testing laboratories to ensure that the standards are accurate, relevant, and up-to-date.
