Efficient Quality Control for Thermal Shrinkage Testing
Lenzing Instruments’ Thermal Shrinkage Tester TST 1 provides efficient quality control by testing one sample with a width of up to 50 mm for percent shrinkage or shrinkage force resulting from heating of the material. The thermal shrinkage properties are analyzed by means of heating the sample at a preset and defined temperature for a specified period of time.
Automated Testing with Precision
After sample loading, the test is performed fully automatically and computer controlled, without any operator influence on the measurement. The specially designed oven-type heater protects the measurement from any ambient influence and together with the high resolution length measuring sensor respectively load cell, TST 1 guarantees for stable testing conditions, highest accuracy and reproducibility of results.
Advanced Testing Capabilities
TST 1 offers the possibility of dynamic tests, at which the behaviour of the material is observed during exposure to a temperature ramp at a constant rate of temperature increase. Subsequent cooling of the sample to ambient temperature enables determination of the residual shrinkage or shrinkage force. Optionally, measurements may be performed according to customized testing sequences.
Real-time Monitoring and Analysis
During the test, the entire shrinkage behaviour is graphically displayed on the connected PC. This enables precise monitoring and analysis of production irregularities, making TST 1 a sophisticated tool for research and development. User friendly software offers flexible and comfortable testing with detailed reports of results.
Standards Compliance
TST 1 is standardized according to ISO 14616 and DIN 53369, ensuring reliable and internationally recognized testing procedures for films, nonwovens, laminated products and fabrics.
