BS EN ISO 2597-1:2010

BS EN ISO 2597-1:2010 is an international standard that establishes the guidelines for the determination of tensile properties of metal materials at elevated temperatures. This standard specifically focuses on the test methods for determining the tensile strength, yield strength, and elongation of metallic specimens.

Importance of Tensile Properties

Tensile properties play a crucial role in evaluating the mechanical behavior and performance of materials under various conditions. The knowledge of these properties is essential for engineers and researchers involved in designing, manufacturing, and quality control processes.

The tensile strength, often referred to as the ultimate tensile strength (UTS), measures the maximum stress a material can withstand before it fractures. It indicates the material's resistance to external forces and determines its ability to withstand loads without permanent deformation or failure. The higher the tensile strength, the more durable and reliable the material is considered to be in structural applications.

In addition to tensile strength, the yield strength is another critical property determined by BS EN ISO 2597-1:2010. Yield strength is the stress at which a material begins to exhibit plastic deformation without any increase in strain. It defines the point at which a material transitions from elastic deformation to plastic deformation and can no longer return to its original shape after the load is removed. Yield strength is particularly important in applications where materials experience repeated stress or cyclic loading.

Test Methods and Procedures

The BS EN ISO 2597-1:2010 standard outlines specific test methods and procedures for accurately determining tensile properties of metal materials at high temperatures.

The specimen preparation involves carefully selecting the appropriate sample dimensions, machining techniques, and surface finishing methods to ensure consistent and reliable results. The standard provides detailed guidelines on specimen shape, dimensions, and marking requirements.

The testing apparatus for tensile tests at elevated temperatures must be capable of accurately controlling the testing temperature and apply a continuous and uniform force along the longitudinal axis of the specimen. The standard specifies various types of test equipment, including furnaces, grips, extensometers, and load cells, along with their calibration procedures.

During the actual testing process, it is crucial to adhere strictly to the standard's instructions to achieve accurate and repeatable results. This includes applying a controlled strain rate, measuring the applied force and specimen extension accurately, and recording all necessary data.


BS EN ISO 2597-1:2010 has become an essential international standard for engineers and researchers involved in materials testing and characterization. By following the guidelines and procedures outlined in the standard, accurate determination of tensile properties at elevated temperatures can be achieved. Understanding and utilizing the tensile strength and yield strength values obtained from these tests allows for better material selection, improved product design, and enhanced overall performance in critical applications.
