1.1 ,This test method covers two procedures for the measurement of the density of materials which are fluid at the desired test temperature. Its application is restricted to liquids of vapor pressures below 80 ,kPa (600 mm Hg) and viscosities below 40 ,000 mm²/s (cSt) at the test temperature. The method is designed for use at any temperature between 20 ,°,C and 100 ,°,C. It can be used at higher temperatures, however, in this case the precision section does not apply.
