Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 The kinematic vi

Thecharts here presented provide a significant improvement inlinearity over the charts previously available under MethodD 341 43. This increases the reliability of extrapolation tohigher temperatures

The charts provide improved linearity in both lowkinematic viscosity and at temperatures up to 340C (approxi

Some high-boiling point materials canshow a small deviation from a straight line as low as 280C(approximately 550F), depending on the individual sample oraccuracy of the data. Reliable data can be usefully plotted inthe high temperature region even if it does exhibit somecur

Experimental data takenbelow the cloud point or temperature of crystal growth willgenerally not be of reliable repeatability for interpolation orextrapolation on the charts. It should also be emphasized th
