ASTM D 341 chart representation

ASTM D 341 chart representation

(OP)
hi everyone,
do someone know about a program to draw the loglog viscosity followed in this code??? excell does not allow a loglog draft.

thanks in advanced  

RE: ASTM D 341 chart representation

Excel can display graphs with logarithmic scales on both axes.  Are you entering negative numbers for temperature?  Change to Kelvins.

RE: ASTM D 341 chart representation

You could also download the graph paper generators at http://www.printfreegraphpaper.com/ and plot the 40/500C and 100OC data and draw a straight line fit as per the ASTM D341 directions (I seem to recall that there are examples in the standard)
