The elevated temperature tensile test according to DIN EN ISO 6892-2 is used to determine mechanical properties such as yield strength, tensile strength, and elongation at break of metallic materials at high temperatures. Hegewald & Peschke offers a customized solution for these tests with the inspekt 250kN universal testing machine, specifically designed for high-temperature tensile testing.

Elevated Temperature Tensile tests are particularly relevant for material development and qualification in high-temperature applications such as aerospace, energy generation, and high-performance materials.

Typical Testing System for Elevated Temperature Tensile Testing According to DIN EN ISO 6892-2

• Testing Machine: The Inspekt 250kN is equipped with an extended testing area and a specialized high-temperature tensile testing setup, enabling tensile tests on metallic materials at temperatures up to 900°C.
• Heating System: The integrated 3-zone furnace ensures precise temperature control based on the surface temperature of the sample. Temperature is measured at three different points on the specimen to ensure uniform heating, providing accurate results and optimal reproducibility.
• Clamping System: A quick-change fixture ensures secure and repeatable positioning of test specimens and provides a positive locking mechanism.
• Deformation Measurement System: The strain of the specimen is measured using a specialized high-temperature extensometer designed for temperatures up to 1500°C. Alternatively, non-contact video extensometer technology can be used.
• Changing Device: An optional changing device with multiple furnaces enables faster test cycles. While one test is in progress, the next specimen can be preheated. As soon as the first test is completed, the next test can begin immediately.

Software and Control

The LabMaster materials testing software from Hegewald & Peschke controls and monitors the entire testing process. It captures real-time measurement data, generates test reports, and integrates seamlessly into existing system environments. The software, equipped with the tensile test module and furnace control module, is optimally tailored to the metal tensile test according to DIN EN ISO 6892-2 and supports all relevant standard requirements.

Additional Testing Methods and Systems for High-Temperature Testing

In addition to tensile testing, bending and compression tests according to standards such as DIN EN 120-1 or ASTM C1211 for ceramics are available to evaluate other mechanical properties under extreme conditions. Suitable testing systems include:

• High-temperature testing system up to 1800°C
• Material testing at high temperatures up to 1200°C
• LCF, HCF, and creep tests with high-temperature radiation furnace
• Composite material testing with temperature chamber
