AbstractAt present, there is no official method for determining the specific gravity of viscous resins. There are, however, official methods for road tars and asphalt cements and for drying oils. In these methods the procedure varies with the viscosity of the material, but in each the most viscous materials are measured by partly filling the pycnometer with the sample. Distilled water is then added so that it, rather than sticky asphalt or oil, is driven out through the capillary. The only difference between the methods is that in ASTM Method D70 the pycnometer is completely immersed in a constant-temperature water bath. One of these methods is usually adopted for use with viscous resins.
