STM-5 is a single-column testing machine equipped with a temperature chamber for high-temperature tensile testing. It operates using a servo-electric mechanism with ball screws, driven by an AC servo motor and driver. Force is measured by a 500 kg load cell, accuracy class 0.5 (max. error 0.5% of the reading from 2% to 100% of the load cell capacity) in compliance with ISO 7500 and EN 10002. The system is equipped with a rectangular temperature chamber and a heating system that ensures uniform temperature distribution. The furnace operates at temperatures up to 100 ˚C, and the heating zone is controlled via a digital controller (resolution 0.1˚C). A thermocouple is provided for measuring both specimen temperature and chamber bulk temperature. The machine features a displacement sensor without stroke limitation, providing 0.3 µm resolution in no load mode and a displacement measurement accuracy better than 0.05 mm at full stroke. The test speed is adjustable from 0.001 to 1000 mm/min. The system supports various low-capacity load cells to improve measurement accuracy, and automatically identifies the load cell and applies the corresponding settings. High-temperature tensile testing can be conducted using the Windows-based JADOO software under rate control in two methods: constant force and constant stress, in accordance with the relevant standards. Load Rate Control for all of machine instrument, Control (Force•, Stress•, Extension•, Strain•, … = cte) Specialized high-temperature jaws for securely clamping rubber and plastic specimens during tensile testing at max. temperature are available upon request The remaining hardware and software capabilities of the machine are identical to those of the STM series (servo electric configuration)
