1.1This 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, and used lubricating oils using a Houillon viscometer in automated mode.
1.2The range of kinematic viscosity capable of being measured by this test method is from 2 mm2/s to 1500 mm2/s (see Fig. 1). The range is dependent on the tube constant utilized. The temperature range that the apparatus is capable of achieving is between 20 °C and 150 °C, inclusive. However, the precision has only been determined for the viscosity range; 2 mm2/s to 478 mm2/s at 40 °C for base oils, formulated oils, diesel oil, biodiesel, and biodiesel blends; 3 mm2/s to 106 mm2/s at 100 °C for base oils and formulated oils; 25 mm2/s to 150 mm2/s at 40 °C and 5 mm2/s to 16 mm2/s at 100 °C for used lubricating oils. As indicated for the materials listed in the precision section.
FIG. 1Houillon Viscometer Typical Viscosity Range of Tube Constants
Note 1:Viscosity range of a Houillon tube is based on most practical flow time of 30 s to 200 s.
1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see Section 6.
