ASTM D7279-20<\/h3>\n

Active Standard: Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids by Automated Houillon Viscometer<\/h4>\n
\n

ASTM D7279<\/h4>\n

Scope<\/strong><\/p>\n

\n

1.1<\/span> This test method covers the measurement of the kinematic viscosity of transparent and opaque liquids; such as base oils, formulated oils, diesel oil, biodiesel, biodiesel blends, residual fuel oils, marine fuels, and used lubricating oils using a Houillon viscometer in automated mode.<\/p>\n<\/p><\/div>\n

\n

1.2<\/span> The range of kinematic viscosity capable of being measured by this test method is from 2\u2009mm2<\/sup>\/s to 2500\u2009mm2<\/sup>\/s (see Fig. 1<\/span>). The range is dependent on the tube constant utilized. The temperature range that the apparatus is capable of achieving is between 20 \u00b0C and 150 \u00b0C, inclusive. However, the precision has only been determined for the viscosity range; 2\u2009mm2<\/sup>\/s to 478\u2009mm2<\/sup>\/s at 40 \u00b0C for base oils, formulated oils, diesel oil, biodiesel, and biodiesel blends; 3\u2009mm2<\/sup>\/s to 106\u2009mm2<\/sup>\/s at 100 \u00b0C for base oils and formulated oils; 25\u2009mm2<\/sup>\/s to 150\u2009mm2<\/sup>\/s at 40 \u00b0C and 5\u2009mm2<\/sup>\/s to 16\u2009mm2<\/sup>\/s at 100 \u00b0C for used lubricating oils; 25\u2009mm2<\/sup>\/s to 2500\u2009mm2<\/sup>\/s at 50\u2009\u00b0C and 6\u2009mm2<\/sup>\/s to 110\u2009mm2<\/sup>\/s at 100\u2009\u00b0C for residual fuels. As indicated for the materials listed in the precision section.<\/p>\n
