Thermo Mechanical Analysis (TMA)
National Technical Systems (NTS)
TMA is used to characterize linear expansion, glass transitions, and softening points of materials by applying a constant force to a specimen while varying temperature. For expansion measurements, a probe rests on a sample on a stage with minimal downward pressure. Other constant force experiments include measurement of penetration, bending, tension, shrinkage, swelling, and creep (sample motion measured as a function of time under an applied load).

Materials Testing
The importance of materials testing cannot be underestimated. Across every major industry, manufacturers, developers and operators of critically important systems, products and components need to be assured that the materials employed in forming their equipment are up to their intended tasks. That’s why the most diligent method of verifying that the materials companies use in manufacturing processes will perform to expectations and adhere to all applicable regulations is through reliable materials testing.
