Dilatometry / Thermomechanical Analysis
DIL / TMA / GST

For highly precise measurement of dimension changes to solids, melts, powders and pastes at a programmed temperature change and with negligible sample strain, dilatometry (DIL) is the method of choice.

With Thermo-Mechanical Analysis (TMA), the measurement of the dimensional changes can additionally be carried out with adjustable sample strain.


NETZSCH instruments of course fulfill the respective instrument and applications standards for Dilatometry - DIL and Thermo-Mechanical Analysis - TMA (e.g. ASTM E 831, ASTM D 696, ASTM D 3386, DIN 51045).
