Metallic materials; Verification of static uniaxial testing machines; Part 1 : Tensile testing machines

This international standard establishes the fundamental metrological requirements for the verification and calibration of static uniaxial testing machines used to evaluate the mechanical properties of metallic materials. It specifically addresses instruments designed to apply tensile forces, ensuring they operate within defined limits of accuracy. The document outlines the procedures necessary to validate the force-measuring system, including the assessment of repeatability, linearity, and hysteresis characteristics across the specified measurement range. It provides detailed guidelines for the selection and use of reference standards, as well as the environmental conditions required during the testing process to minimize external influences. By adhering to these protocols, testing facilities can ensure the reliability and comparability of their results. This approach supports quality assurance in the manufacturing and research sectors by maintaining consistent equipment performance. The scope covers the specific configuration of tensile testing apparatus, detailing how to check force indicators and control systems. Compliance with these criteria facilitates mutual recognition of test data between different laboratories and industries globally.
