ASTM D7279

This is an ASTM International Standard Test Method for the analysis of viscosity in used and new lubricants. The Spectro-Visc meets and exceeds the requirements of this specification. Copies of the complete method are available from the ASTM web site at http://www.astm.org. The full title and partial scope of the method is listed below:

ASTM D7279-06 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids by Automated Houillon Viscometer

• 1. Scope
• 1.1 This test method covers the measurement of the kinematic viscosity of transparent and opaque liquids such as fresh and used lubricating oils using a Houillon viscometer in automated mode.
• 1.2 The range of kinematic viscosity covered by this test method is from 0.2 to 1000 mm2/s in the temperature range between 20°C and 150°C; however, the precision has only been determined for the materials, viscosity range, and temperatures as stated in the precision section (viscosity range 25 to 150 mm2/s at 40°C and 5 to 16 mm2/s at 100°C).
