In extreme cases, an additional determination at a third temperature is advisable. T, v, X, Y, X1, Y1.

An American National Standard Designation: It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. This test method details the standard procedure for plotting viscosity-temperature charts that ascertain the kinematic viscosity of a petroleum oil or liquid hydrocarbon at any temperature within a limited range, provided that the kinematic viscosities at two temperatures are known.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.

Kinematic viscosities or temperatures for other points can then astn readily calculated. A point on this line, within the range defined in Section 3, shows the kinematic viscosity at the corresponding desired temperature and vice versa. You could build a table: With computers that seems like the easy way. Originally approved in Defense manufacturing is all about project manufacturing and project accounting.


It is provided for convenience in connection with reports and data evaluation. This increases the reliability of extrapolation to higher temperatures.

Then if you a simple excel linear plot Y vs X or log log excel plot based on Y1 vs X1 I think you d3341 have a straight line on your graph slope 1 on the linear plot.

It should be noted that this value is not the value of B given in Eq D431. I’m trying to basically make my own plot The ASTM Slope was originally obtained by physically measuring the slope of the kinematic viscositytemperature data plotted on the older charts given in Test Method D — Link to Active This link will always route to the current Active version of the standard.

This standard astmm been approved for use by agencies of the Department of Defense. Easier for you to build but not as pretty when you’re done. Thanks for sharing your spreadsheet. Promoting, selling, recruiting, coursework and thesis posting is forbidden.

Plotting Viscosity Data and making the ASTM D Graph Logarithms actually if you look more carefully you will notice that the horizontal scale is c341 log scale in K, but usually values are shown in degrees C and the vertical scale is a loglog scale.
