THERMAL NEWS GROUP: Hi, Albert - There are no ASTM standards for volumetric expansion using
thermomechanical analysis. Sorry.
Most thermomechnaical analyzers vendors offer a quartz or glass
"dilatometer" for examining volumetric expansion. This devices are
cylinder-piston arrangements that use some spherical filling medium to
translate the three dimentional expansion of a substance into a one
dimensional motion. These dilatometers work well for solid samples and
less well for viscous liquids and pastes. They don't work at all for low
viscosity liquids that actually flow and pour. This is because the seal
between the piston and the cylinder is not liquid tight.
A few years ago, there was an article in one of the thermal analysis
journals, such as "Thermochimica Acta" or "Journal of Thermal Analysis and
Calorimetry" (nee J. Therm. Anal.), by two authors who fixed a plastic
syringe to the TMA fixtures and used that for measuring low viscosity
liquids. I have been unable to re-locate that article. Does anyone else
remember seeing it?
Best regards,

THERMAL NEWS GROUP: Dear THERMAL Subscribers:
I have been asked by a customer to determine the coefficient of
thermal expansion of a liquid monomer. I tried to find an ASTM method but
without luck. Any suggestions? Thanks in advance for your help.
