In rubber the curing process is also called vulcanization. As rule the equations for getting viscosity from flow time are empirically determined each cup by way of calibration tests with reference standards. The same word in some cases Latinized Lygus was used botany and zoology for various taxonomic groups component of names . That is substances which are neither completely elastic nor entirely viscous. To measure viscosity laminar flow required

For example submitting fluid to too high shear rate during the test can result turbulent flow. Any change in temperature always influences viscosity but for different fluids the size of this varies. Figure Comparing highviscosity fluid to lowviscosity . Generally microviscometer best suited for measuring liquids the lowviscosity range

For a Newtonian liquid this function straight line curve see figure. The greater part of automated capillary viscometers features special capillaries working with less measuring volume than original types covering extended viscosity range
