Function

Test the thermal shrinkage performance of materials, including thermal shrinkage rate, thermal shrinkage force, cold shrinkage force, etc.

Principle

Cut the samples according to the standard requirements (3 groups, 2 pieces per group), and install them into sample clamps in groups. After the instrument controls the constant temperature test chamber to the specified temperature, press the "Test" button and the instrument enters the fully automatic workflow: the instrument pushes the sample into the constant temperature chamber; each group has 2 samples, one for measuring shrinkage force (the sample fixture does not move) and one for measuring shrinkage rate (the sample shrinks, the fixture moves under force, and the sample stress is kept below 0.1N); Automatically end the experiment and calculate the test data.

Compliant with standards

ISO-14616-1997、DIN 53369-1976。
