Many petroleum products are tested for their viscosity, thus making viscosity testing an essential focus in our industry. Therefore, it is important to hold a high standard for the instrumentation used for viscosity testing. Recently, there has been a push to improve the viscosity instrumentation available in the market, to help simplify the testing procedure while maintaining accurate results. These new instruments are easy to use with automatic operations, produce accurate and consistent results, can test many samples per hour, can handle a wide variety of samples, use only a small amount of sample and cleaning solvent, and are manageable to service. Additionally, instrumentation using both Ubbelohde and Houillon tube designs has seen these improvements. These advances as well as recent changes in the ASTM methods are discussed in this paper. When considering ASTM methods, the newly developed instruments can be used for ASTM D445, ASTM D446, ASTM D2170, ASTM D2171, ASTM D2270, and ASTM D7279. Overall, the recent advances in viscosity instrumentation will serve our industry efficiently and effectively for years to come.
