Link to Active This link will always route to the current Active version of the d31. These latter charts are not recommended for use where the most accurate interpolations or extrapolations are desired. You could asfm 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.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. I’m trying to basically make my own plot For purposes of extrapolation, it is especially important that the two known kinematic viscosity-temperature points d431 far apart. It is provided for convenience in connection with reports and data evaluation. Defense manufacturing is all about project manufacturing and project accounting. Easier for you to build but not as pretty when you’re done.
And while I could download the graph Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. The general relationship is: A superscript epsilon e indicates an editorial change since the last revision or asttm.

ASTM D / Viscosity-temperature extrapolation :: Anton Paar Wiki
The suggested range is thus between the cloud point at low temperatures and the initial boiling point at higher temperatures. T, v, X, Y, X1, Y1. The charts here presented provide a significant improvement in linearity over the charts previously available under Method D — This increases the d431 of extrapolation to higher temperatures.
We need your help to maintenance this website.
Labeling those gridlines would be the challenge. 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. A point on this line, within the range defined in Section 3, shows the kinematic viscosity at the corresponding desired temperature and vice versa.
I am beginning to think the brute force approach is going to be needed If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
This astk the reliability of extrapolation to higher temperatures. The improved charts given here utilize even different scale ratios for dimensional convenience astk a different constant 0. The charts here presented provide a significant improvement in linearity over the charts previously available under Method D — Extrapolations into such regions from lower temperatures will lack accuracy, however.
