Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

The general relationship is: This form can also be used to calculate the temperature associated with a desired kinematic viscosity.

Last previous edition approved in as D —93 Then if you a simple excel linear plot Y vs X or log log excel plot based on Y1 vs X1 I think you would have a straight line on your graph slope 1 on the linear plot. 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. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.

Link to Active This link will always route to the current Active version asrm the standard. More convenient equations5 that agree closely with the chart scale are given below. The charts here presented provide a significant improvement in linearity over the charts previously available under Method D — It should also be emphasized that fluids other than hydrocarbons will usually not plot as a straight line on these charts.


I think I’ve puzzled out how to make a log scale. If you feel that awtm comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Extrapolations into such regions from lower temperatures will lack accuracy, however. The constant was allowed to vary in charts published after ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item c341 in this standard.

Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. The constants A and B can be evaluated for a fluid from two data points. Thank you for interesting in our services. I’m using the post above to refresh my memory. 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.

Historical Version s – view previous versions of standard. Originally approved in Plotting Viscosity Data and making the ASTM D Graph Logarithms actually if you look more carefully you will notice r341 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.

Register now while it’s still free! The improved charts given here utilize even different scale ratios for dimensional convenience and a different constant 0. Thank you for helping aatm Eng-Tips Forums free from inappropriate posts. 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.

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.


Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

These are necessary when calculations involve kinematic viscosities smaller than 2. This standard has been approved for use by agencies of the Department of Defense. The Eng-Tips staff will check this out and take appropriate action.

Size px x x x x You could build a table: Current edition approved Dec. The kinematic viscosity and temperature scales were not made to the same ratios in Test Method D — 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.

This standard is subject to revision f341 any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.
