THERMOMECHANICAL
ANALYSIS (TMA)
DILATOMETRY (DIL)
DIN 51045, ASTM E 831, ASTM D 696, ASTM D 3386
This is a technique by which the dimensional changes of the sample are
monitored as a function of temperature or time, while the sample may
be subjected to an additional mechanical load.
- negligible mechanical load Æ dilatometry
- constant load Æ (static) thermomechanical analysis
- oscillating force Æ dynamic mechanical analysis
DL = length change
DL / L
0 = relative length change
a = coefficient of linear thermal expansion
T
g = glass transition temperature
expansion/shrinkage/penetration behavior
dimensional stability Æ design purposes
softening/curing behavior
volumetric expansion (Þ bulk density)

DYNAMIC
MECHANICAL ANALYSIS (DMA)
DIN 53513, DIN 53440, ASTM D 4065, ASTM D 4092
This is a thermoanalytical method by which the mechanical behavior of
a sample subjected to a specific temperature program is investigated under
the effect of a load which changes with time.
Determination of the storage and loss moduli and the damping factor of a
sample as a function of temperature, time and frequency of an applied oscillating
load.
