I’m remembering now given two sets of T,v you can solve the constants and plot a curve in the T,v plane which is not a straight line and read off any value you want. This abstract is a brief summary of the referenced standard. 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 — I think I’ve puzzled out how to make a log scale.

Please fill this form, we will try to respond as soon as possible. These are necessary when calculations involve kinematic viscosities smaller than 2. Labeling those gridlines would be the challenge. The charts here presented provide a significant improvement in linearity over the charts previously available under Method D — We need your help to maintenance this website.

You could build a table: In extreme cases, an additional determination at a third temperature is advisable. Close this window and log in. The ASTM d chart uses this scale. Red Flag This Post Please asm us know here why this post is inappropriate. With computers that seems like the easy way.

But, the log log needed for this equation isn’t working out. 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.

I’m trying to basically make my own plot An American National Standard Designation: More convenient equations5 that agree closely asttm the chart scale are given below. Plotting Viscosity Data and making the ASTM D Ast Logarithms actually if you look more carefully you will notice that the horizontal scale is a log scale in K, but usually values are shown in degrees C and the vertical scale is a loglog scale. Easier for you to build but not as pretty when you’re done.

Thanks for sharing your spreadsheet. The only problem is the axes are not v and T.

I am beginning to think the brute force approach is going to be needed And while I could download the graph Draw a sharply defined straight line through them. The general relationship is: Historical Version s – view previous versions of standard. We need your help! This standard has been approved for use by agencies of the Department of Defense. 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by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.

It is provided for convenience in connection with reports and data evaluation. D — 03 Standard Test Method for Viscosity-Temperature Charts for Liquid Petroleum Products1 This standard is issued under the fixed designation D ; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

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.

The constant was allowed to vary in charts published after Are you asgm Engineering professional? A superscript epsilon e indicates an editorial change since the last revision or reapproval. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
