Excerpt from Determination of Absolute Viscosity by Short-Tube Viscosimeters Unfortunately none of the units of T able 1 have been generally employed by oil refiners and jobbers, although, according to Denton,7 tests for viscosity have been in use for over 30 years. In the oil industry in the United States viscosity is usually meas ured by an instrument called a viscosimeter or viscometer, which permits a certain volume of oil to discharge through a short capillary tube, the viscosity, so called, being reported as the time of discharge in seconds, a value which is of little significance unless the make of instrument is stated and is well known.

This book is written for scientists involved in the calibration of viscometers. A detailed description for stepping up procedures to establish the viscosity scale and obtaining sets of master viscometers is given in the book. Uncertainty considerations for standard oils of known viscosity are presented. The modern viscometers based on principles of tuning fork, ultrasonic, PZT, plate waves, Love waves, micro-cantilever and vibration of optical fiber are discussed to inspire the reader to further research and to generate improved versions. The primary standard for viscosity is pure water. Measurements of its viscosity with accuracy/uncertainty achieved are described. The principles of rotational and oscillation viscometers are explained to enhance the knowledge in calibration work. Devices used for specific materials and viscosity in non SI units are discussed with respect to the need to correlate viscosity values obtained by various devices. The description of commercial viscometers meets the needs of the user.
