Test method for determining the strength of materials
In a tensile test, standardized specimens with a defined cross-sectional area are stretched to fracture, with the strain or displacement being increased uniformly, shock-free and at a low rate. As a rule, a tensile test is used either for metallic materials or for plastics; depending on the material, different standard specifications must be taken into account. TÜV NORD tests the strength of metallic materials of all types, for example, in static tensile tests according to DIN EN ISO 6892-1, test method A (based on strain rate, displacement-controlled) with and without fine strain measurement and test method B (based on stress rate, load-controlled) on testing machines with up to 1,200 kN test load.
Hot tensile test - tensile test at elevated temperature
Hot tensile tests according to DIN EN ISO 6892-2 can be carried out at up to 1,000°C using a hot testing unit. Our cooling unit allows tensile tests down to - 150°C or at -196°C in liquid nitrogen.
Tensile specimens can be made from steels of reinforcements, strips, sheets, tubes, bars, pipe bends, fittings, forgings and castings, chains, welds, brazed and bonded joints.
