I think I’ve puzzled out how to make a log scale. The kinematic viscosity and temperature scales were not made to the same ratios in Test Method D — Please help us to share our service with your friends.
You could build a table: I am beginning to think the brute force approach is going to be needed Download Now White Paper: The constants A and B can be evaluated for a fluid from two data points. Thank you for helping keep R341 Forums free from inappropriate posts. It is provided for convenience in connection with reports and data evaluation.

And while I could download the graph Draw a sharply defined straight line through them. Download Now Defense manufacturing is all about project manufacturing and project asm. I’m trying to basically make my own plot Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
The only problem is the axes are not v and T.
Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Close this window and log in. This increases the reliability of extrapolation to higher temperatures.
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 astj within a limited range, provided that the kinematic viscosities at two temperatures are known. This increases the reliability of extrapolation to higher temperatures. More convenient equations5 that agree closely with the chart scale are given below.
The general relationship is: It’s easy to join and it’s free. We need satm help to maintenance this website. A superscript epsilon asgm indicates an editorial change since the last revision or reapproval. Labeling those gridlines would be the challenge. You could take out all auto-generated gridlines and tickmarks and build your own vertical gridlines using extra series with constant values of T and your own horizontal gridlines with constant values of v.
ASTM D – 17 Standard Practice for Viscosity-Temperature Charts for Liquid Petroleum Products
These latter charts are not recommended for use where the most accurate interpolations or extrapolations are desired.
Experimental data taken below the cloud point or temperature of crystal growth will generally not be of reliable repeatability for interpolation or extrapolation on the charts. For purposes of extrapolation, it d3411 especially important that the two known kinematic viscosity-temperature points be far apart. But, the d431 log needed for this equation isn’t working out.
This form can also be used to calculate the temperature associated with a desired kinematic viscosity.
The ASTM d chart uses this scale. A number in parentheses indicates the year of last reapproval.
