ISO 2811: Density-Grease Pycnometer – need temperature

SO 2811 – Paints and Varnishes – Determination of Density – Part 1 – Pycnometer Method

This test determines the density of a grease, paste or emulsion using a special metal pycnometer. One example of the test’s usefulness is in determining the density of lubricant emulsions including those used in metal working, fabric processing and as mold release agents. The density of these emulsions may give an indication of their compositions and verify that they are the density required for the processing equipment on which they will be used.

A calibrated metal pycnometer is weighed, filled with sample and equilibrated at the test temperature. The cap is firmly pushed into place allowing any accumulated air bubbles and excessive sample to come through a hole in the lid. The pycnometer containing the sample is weighed and the sample density is reported in grams per cubic centimeter.
