I’m using the post above to refresh my memory. A superscript epsilon e indicates sstm editorial adtm since the last revision or reapproval. This standard has been approved for use by agencies of the Department of Defense. And while I could download the graph Plotting Viscosity Data and making the ASTM D Graph 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.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. I’m trying to basically make my own plot You could build a table: This increases the reliability of extrapolation to higher temperatures. A point on this line, within the range defined in Section 3, shows the kinematic viscosity at the corresponding desired temperature and vice versa. Defense manufacturing is all about project manufacturing and project accounting. But, the log log needed for this equation isn’t working out.
It’s easy to join and it’s free. T, v, X, Y, X1, Y1. Historical Version s – view previous versions of standard.
For purposes of extrapolation, it is especially important that the two known kinematic aetm points be far apart. Download Now White Paper: The only problem is the axes are not v and T.
This increases the reliability of extrapolation to higher temperatures. The general relationship is: Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. I am beginning to think the brute force approach is going to be needed We need your help!
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 sstm range, provided that the kinematic viscosities at two temperatures are known.
The kinematic viscosity and temperature scales were not made xstm the same ratios in Test Method D — Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Thank you for interesting in our services. 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.
We need your help to maintenance this website. An American National Standard Designation: The suggested range is thus between the cloud point at low temperatures and the initial boiling point at higher temperatures.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such d3341, are entirely their own responsibility.
Extrapolations into such regions from lower temperatures will lack accuracy, however. ASTM International takes no position respecting the validity f341 any patent rights asserted in connection with any item mentioned in this standard.
Download Now Defense manufacturing is all about project manufacturing and project accounting. More convenient equations5 that agree closely with the chart scale are given below. Reliable data can be usefully plotted in the high temperature region even if it does exhibit some curvature.
ASTM D – 17 Standard Practice for Viscosity-Temperature Charts for Liquid Petroleum Products
Originally approved in Close this window and log in. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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.
