You may want to try looking at a method released by AOCS (American oil
chemist society) that uses a test method to measure thermal expansion of
oils in the liquid state. I think its called the fat index, it may work for
what you need.

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.

Albert,
when I was working at Shimadzu, we did some work on the thermal expansion of
starches and some liquids. It was for somebody in France working on food
research (Montpellier?).
We were using a standard Al pan (6 mm dia x 7 mm height). We put another Al
pan on top (the other way around) whose dimensions were 5.5 mm dia x 2 mm
height. Those pairs were usually used with the Shimadzu automatic DSC. On
top of this pan the expansion probe (3 mm dia) was put at a very small force
(less 0.5 g). The results were pretty good and well reproducible.
Best regards

Hi, Robert - You might check the paper titled "Lead-Tin Solder
Characterization by Differential Scanning Calorimetry" by Mark Fleszar
appearing in the Proceedings of the 27th Conference of the North American
Thermal Analysis Society pages 175- 180.
There is also the paper title "Determination of the Liquidus Temperature and
Composition of Tin/Lead Solders by DSC" by Valerie Kuck published in TA
Instruments (nee DuPont) "Hotline" newsletter some years ago.
Since neither of these publications is copyright, I will send copies of
these publications to you by fax.
