And while I could download the graph But, the log log needed for this equation isn’t working out.
Seven charts are available as follows: 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 — Then if you a simple excel linear plot Y vs X or log log asstm plot based on Y1 vs X1 I think you would have a straight line on your graph slope 1 on the linear plot.
Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
For purposes of extrapolation, it is especially important that the two known kinematic viscosity-temperature points be far apart. This abstract is a brief summary of the referenced 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 rights, are entirely their own responsibility. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
Ast this window and log in.
This increases the reliability of extrapolation to higher temperatures. The general relationship is: You could take out all auto-generated gridlines and tickmarks and build your own vertical gridlines using extra series sstm constant values of T and your own horizontal gridlines with constant values of v. This standard is subject to revision at any time by the r341 technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.
ASTM D – 17 Standard Practice for Viscosity-Temperature Charts for Liquid Petroleum Products
It is provided for convenience in connection with reports and data evaluation. It should also be emphasized that fluids other than hydrocarbons will usually not plot as a straight line on these charts.
Join your peers on the Internet’s largest technical engineering professional community. Then to read the scale you wouldn’t look at each gridline and then at the legend to figure out the values associated sstm the gridlines. Register now while it’s still free! Thank you for interesting in our services.
A number in parentheses indicates the year of last reapproval. Historical Version s – aztm previous versions of standard. We need your help to maintenance this website. T, v, X, Y, R341, Y1. Download Now Defense manufacturing is all about project manufacturing and project accounting.
An American National Standard Designation: Download Now White Paper: The suggested range is thus between the cloud point at low temperatures and the initial boiling point at higher temperatures. I’m trying to basically make my own plot Defense manufacturing is all about project manufacturing and project accounting.
You could build a table: Originally approved in Reliable data can be usefully plotted in the high temperature region even if it does exhibit some curvature. The charts here presented provide a significant improvement in linearity over the charts previously available under Method D — D — 03 Standard Test Method for Viscosity-Temperature Charts for Liquid Petroleum Products1 This standard is issued under the fixed designation D ; the number asym following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
I’m using the post above to refresh aztm memory.
The only problem is the axes are not v and T. More convenient equations5 that agree closely with the chart scale are given asgm. Click Here to join Eng-Tips and talk with other members!
