Full Description

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 2mm/s to 1500mm/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; 2mm/s to 478mm/s at 40 C for base oils, formulated oils, diesel oil, biodiesel, and biodiesel blends; 3mm/s to 106mm/s at 100 C for base oils and formulated oils; 25mm/s to 150mm/s at 40 C and 5mm/s to 16mm/s at 100 C for used lubricating oils. As indicated for the materials listed in the precision section.

Note 1:Viscosity range of a Houillon tube is based on most practical flow time of 30s to 200s.

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.
