What is Saybolt Furol viscosity test?
Saybolt Furol viscosity test is used to determine viscosity of liquid bitumens. 10.6.2. Scope. In this test, time in seconds is noted for 60 ml of the liquid bitumen at specified temperature to flow through an orifice of a specific size.
Is Saybolt code viscosity?
VISCOSITY TEST OF BITUMEN EMULSION BY SAYBOLT FUROL VISCOMETR (IS-3117-2004)
Which size in micron sieve is used for straining the emulsion in the Saybolt Furol viscosity test?
150 micron
Clean the oil tube with a solvent, such as benzene, and remove excess solvent from the gallery. Sieve the all sample through a 150 micron IS sieve before pouring into the oil tube.
What is meant by Saybolt viscometer?
Definition of Saybolt viscosity : viscosity as determined by the number of seconds required for an oil heated to 130° F for lighter oils and 210° F for heavier oils to flow through a standard orifice and fill a 60 milliliter flask.
What does Furol mean?
FUROL is an acronym for fuel and road oil. Saybolt universal viscosity is specified by the ASTM D2161. Both tests are considered obsolete to other measures of kinematic viscosity, but their results are quoted widely in technical literature.
What is viscosity test of bitumen?
Viscosity test of the bitumen sample is one of the important tests on bitumen to be conducted before road construction. Viscosity measures the degree of fluidity of the bitumen sample. It ensures the quality of the bitumen used as a binder by giving a measure of fluidity at a particular temperature.
What is the range of viscosity of bitumen?
Application of viscosity grade bitumen
| Grade | Viscosity Range at 60°C (Absolute Viscosity) |
|---|---|
| VG-10 Bitumen | 800-1200 |
| VG-20 Bitumen | 1600-2400 |
| VG-30 Bitumen | 2400-3600 |
| VG-40 Bitumen | 3200-4000 |
What is a Furol?
What is viscosity test?
Services Viscosity Testing The kinematic method uses gravity to force the sample through a glass viscometer (such as Ubbelohde) containing a capillary of known dimensions. This technique is good for Newtonian fluids and can be used to determine the intrinsic or inherent viscosity of a material.
How do we measure the viscosity of bitumen?
It is measured by a vacuum capillary viscometer. To measure the viscosity, a capillary (very thin) tube is placed in the water bath. The temperature of the water bath can be both 60 °C or 135 °C. The time that takes to pass bitumen through the capillary tube is recorded.
How viscosity test is done?
Viscosity can also be measured by applying oscillating vibrations to the sample and monitoring the damping effects of the fluid. These can be assessed by monitoring power input, the decay time of oscillations, or changes in the resonated frequency.
What are the uses of viscosity test?
Viscosity measurements are used in the food industry to maximize production efficiency and cost effectiveness. It affects the rate at which a product travels through a pipe, how long it takes to set or dry, and the time it takes to dispense the fluid into packaging.
Which apparatus is used for viscosity test of bitumen?
Saybolt Furol Viscometer
APPARATUS USED Viscometer- A Saybolt Furol Viscometer.
What is a viscosity test?
Viscosity is a measurement of a material’s resistance to flow, typically a fluid. Viscosity can be measured using two different approaches: Dynamic shear viscosity: shear stress (force) is mechanically applied to the fluid, and the rate the fluid layer moves over a stationary material is measured.
What is the difference between the Saybolt universal and Saybolt FUROL tests?
The Saybolt universal viscosity test occurs at 100 °F (38 °C), or more recently, 40 °C (104 °F). The Saybolt FUROL viscosity test occurs at 120 °F (49 °C), or more recently, 50 °C (122 °F), and uses a larger calibrated tube. This provides for the testing of more viscous fluids, with the result being approximately 1⁄10 of the universal viscosity.
What is the viscosity test for FUROL?
The Saybolt FUROL viscosity test occurs at 120 °F (49 °C), or more recently, 50 °C (122 °F), and uses a larger calibrated tube. This provides for the testing of more viscous fluids, with the result being approximately 1⁄10 of the universal viscosity.
What is the temperature of the Saybolt universal viscosity test?
The Saybolt universal viscosity test occurs at 100 °F (38 °C), or more recently, 40 °C (104 °F). The Saybolt FUROL viscosity test occurs at 120 °F (49 °C), or more recently, 50 °C (122 °F), and uses a larger calibrated tube.
What is the use of Saybolt viscometer?
SAYBOLT VISCOMETER. A device used to measure the viscosity of a fluid. The saybolt viscometer controls the heat of the fluid and the viscosity is the time is takes the fluid to fill a 60cc container. The device used for measurement of viscosity is known as viscometer .
