What is the importance of Saybolt viscosity test?

What is the importance of Saybolt viscosity test?

Saybolt Furol viscosity test is used to determine viscosity of liquid bitumens. 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. The higher the viscosity of the bitumen more time will be required for a quantity to flow out.

What is the unit of Saybolt Universal viscometer?

seconds
The unit of measure is time in seconds; it is reported as Saybolt Universal Seconds (SUS); for example, 350 SUS at 100 F. The Saybolt Furol Viscometer is the same in principle as the Universal Viscometer with the exception that it is designed with a larger orifice to accommodate more viscous fluids.

How many types of Saybolt viscosity are there?

There are two types: 1-saybolt universal viscosity: It is the corrected efflux time in seconds of 60 mL of sample flowing through a calibrated universal orifice under specified condition. The viscosity value is reported in Saybolt universal seconds abbreviated SUS, at a specified temperature.

What is Saybolt Furol viscosity?

Saybolt Furol viscosity – the efflux time in seconds required for 60 milliliters of a petroleum product to flow through the calibrated orifice of a Saybolt Purol viscometer, under carefully controlled temperature, as prescribed by test method ASTM D 88.

What is Saybolt color?

Saybolt color (reference ASTM D156, ASTM D6045) is primarily used in characterizing fuels including automobile and aviation gasolines, jet fuel, diesel fuel and other petroleum products. The Saybolt color scale varies from near water white (30) to dark yellow (-16).

Which oil is used in Redwood viscometer?

A redwood viscometer is used to measure the flow of eight different liquids including engine oil, sunflower oil, soybean oil, glycerol, thermic fluid (Hy- therm), coconut oil, water and ghee.

What is Saybolt number?

ASTM D156 defines the Saybolt color scale (+30 to -16 Saybolt) Used for determining the color of: Gasoline. Jet fuel. Kerosene.

What is ASTM Colour?

Sometime referred to as the “mineral oil color value”, the ASTM Colour Scale is widely used for the grading of petroleum products such as lubricating oils, heating oils and diesel fuel oils.

What is ASTM D1500?

ASTM D1500 is a single number, one dimensional, colour scale ranging from a pale straw through to a deep red in sixteen steps (0.5 – 8.0 units in increments of 0.5 units). Visual Comparators can achieve a resolution of 0.5 units, automatic Lovibond® PFX and PFXi instruments achieve a resolution of 0.1.

What is VI improver?

VI improvers (also known as viscosity modifiers) are additives that increase the viscosity of the fluid throughout its useful temperature range.

What color is Saybolt?

Saybolt color (reference ASTM D156, ASTM D6045) is primarily used in characterizing fuels including automobile and aviation gasoline, jet fuel, diesel fuel and other petroleum products. The Saybolt color scale varies from near water white (30) to dark yellow (-16).

What is ASTM scale?

What is D86 distillation?

ASTM D86 is the standard test method used to experimentally measure the batch distillation curve of a petroleum-derived fuel at atmospheric pressure [4]. A distillation curve obtained using the ASTM D86 method is commonly known as a D86 distillation curve.

What is Saybolt Colour?

The Saybolt Colour scale is used for grading light coloured petroleum products including aviation fuels, kerosine, naphthas, white mineral oils, hydrocarbon solvents and petroleum waxes.

What is viscosity improver?

A viscosity index improver is a complex polymer additive that expands at elevated temperatures to thicken the lubricant and ensure a more stable and consistent viscosity. This ensures the lubricant fully protects the equipment at both low and high temperatures.
