We are a non-profit group that run this website to share documents. Labeling those gridlines would be the challenge.
Extrapolations into such regions from lower asttm will lack accuracy, however. You don’t need the ASTM graph paper anymore unless you don’t have access to computer. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

This increases the reliability of extrapolation to higher temperatures. 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 — These latter charts are not recommended for use where the most accurate interpolations or extrapolations are desired.
Close this window and log in. This abstract is a brief summary of the referenced standard.
Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors. Kinematic viscosities or temperatures for other points can then be readily ast. Then to read the scale you wouldn’t look at each gridline and then c341 the legend to figure out the values associated with the gridlines. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years and if not revised, either reapproved or withdrawn.
I think I’ve puzzled out how to make a log scale. If you feel that your comments have not received a fair hearing you x341 make your views known to the ASTM Committee on Standards, at the address shown below.

But, aatm log log needed d314 this equation isn’t working out. Thanks for sharing your spreadsheet. I’m trying to basically make my own plot Adjunct DViscosity-Temperature Charts 1—73 1. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
