Water and Sediment in Middle Distillate Fuels

This test method determines the amount of water and sediment in middle distillate fuels (e.g., diesel fuel, fuel oils) using centrifugation. These impurities can cause corrosion, filter plugging, and poor combustion performance.

Viscosity R&D

This test method is a procedure for the measurement of viscosity of liquids using a digital rotary viscometer. This method can capture data points at a multitude of temperatures, rotational speeds, and rotor diameters, and is especially effective for data determination in non-Newtonian fluids

Unsaponifiable Matter

This test method is a standard analytical procedure used to determine the unsaponifiable matter content in fats and oils. Unsaponifiable matter includes components that do not form soaps when treated with alkali, such as sterols, hydrocarbons, alcohols, and certain vitamins.

Temperature

This test method is used to determine the temperature of a substance using a certified thermometer.

Titer

This test method is the official Titer Test, which determines the solidification point of the fatty acids obtained from a saponified fat or oil sample. It is applicable to animal fats, vegetable oils, and marine oils and is used to characterize hardness and composition.

Total Fatty Acids

This test method is a standardized procedure developed by the American Oil Chemists’ Society for determining total fatty acids in fats and oils.

Saponification Value

This test method is a standardized procedure to determine the saponification value of fats and oils, which measures the amount of potassium hydroxide (KOH) in milligrams required to saponify one gram of the sample.

Soap in Oils

This test method is a standardized procedure used to determine the soap content in fats and oils, particularly refined vegetable oils. This method is crucial for processors monitoring the efficiency of oil refining and verifying product compliance with industry standards.

Soluble Protein Potassium Hydroxide

This test method determines potassium hydroxide (KOH) protein solubility, and is an effective, rapid screening tool to detect overprocessing in oilseed byproducts.

Specific Gravity / Density

This test method is an official method used to determine the specific gravity and density of alcoholic beverages. The method involves measuring the mass and volume of a known quantity of sample at a standardized temperature. Specific gravity is calculated as the ratio of the sample’s density to the density of water at the same… Continue reading Specific Gravity / Density
