We perform testing on oils, lubricants, and fuels, and we use ASTM D2161 to convert kinematic viscosity to Saybolt Universal or Saybolt Furol viscosity.
We also perform viscosity testing by ASTM D1092, ASTM D2270, ASTM D2422, ASTM D2532, ASTM D2983, ASTM D341, ASTM D445, IP 226, IP 71, ISO 2909, and ISO 3104. These different test methods use different instruments or procedures or are used for certain sample types. Click on the test method number to learn more about each test.
