ASTM D341
Plot viscosity–
temperature curve
Visually compare up to 4 oils on a viscosity-temperature chart. Enter ν40 and ν100 and the curve is calculated per ASTM D341.

Curves calculated using the ASTM D341 (Walther method): W(T) = log₁₀(log₁₀(ν + 0.7)) = A + B·log₁₀(T[K]). Valid for mineral and conventional synthetic oils between −20 °C and 150 °C. Not applicable to polar oils, greases or non-Newtonian products.
