Saybolt Universal Seconds (SUS) or Saybolt Furol Seconds (SFS) are units used to measure viscosity.īrookfield Rotational Viscometer Test: The Brookfield Rotational Viscometer is a cutting-edge device used to gauge bitumen viscosity. The bitumen takes longer to flow the greater the viscosity. It is timed how long it takes for a certain amount of bitumen to pass through the tube. In this test, a predetermined amount of heated bitumen is poured into a calibrated viscometer tube after being heated to a certain temperature (usually 135☌). Saybolt Furol Viscosity Test: An empirical test technique used to determine the viscosity of bitumen at a certain temperature is the Saybolt Furol Viscosity test. The two most popular techniques for calculating bitumen 60/70's viscosity are: Techniques for Measuring Viscosity: There are several ways to measure the viscosity of bitumen, from conventional methods to more sophisticated and accurate ones. This article will go through how bitumen 60/70, a regularly used grade in road building, is measured for viscosity. Bitumen's viscosity, or resistance to flow, is a crucial factor in evaluating its quality and applicability for certain uses. The choice of method depends on factors such as the desired accuracy, precision requirements, availability of equipment, and specific industry standards.īitumen, a very viscous and semi-solid type of petroleum, is essential to many sectors of the economy, including waterproofing, roofing, and road building. The system makes use of a distinctive single position auto-sampling that offers integrated sample heating of up to 200 ✬ and utilizes a preheated solvent to efficiently clean the viscometer tube.The viscosity of bitumen 60/70 can be accurately measured using either the Saybolt Furol Viscosity test or the Brookfield Rotational Viscometer test. Measurements are conducted with excellent accuracy and within acceptable temperature stability with the help of sophisticated temperature control.

Fully opaque fluids without any challenges or limitations can be detected using these tubes, and the need to use reverse-flow tubes is eliminated, thanks to specially designed thermal sensors. The well-known and tested Ubbelohde design serves as the foundation for viscometer tubes. The BitUVisc is a member of the U-Visc family of completely automatic viscometer systems from Omnitek. This automatic kinematic viscometer model fully complies with ASTM D445 and D2170 and was specifically designed to address sample types that pose a great threat to automatic sampling, measurement, and cleaning as a result of their viscosity and high pour point. With Omnitek BitUVisc it is possible to test samples with high viscosities what is considered 'extreme samples' for the kinematic viscometer market.
