ASTM D7279

This is an ASTM International Standard Test Method for the analysis of viscosity in used and new lubricants. Our S-flow systems all meet and exceed the requirements of this specification. Copies of the complete method are available from the ASTM web site at 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).
