ISO 20336 Apparatus for Total Sulfur of Solid Mineral Fuels
KN-20336 Apparatus for Total Sulfur of Solid Mineral Fuels conforms to ISO 20336 Solid mineral fuels----Determination of total sulfur by Coulomb titration method. In the presence of the catalyst, a weighed sample is combusted at 1150℃ in a stream of purified air. The sulfur oxides are formed and dissolved in the electrolytic solution. The sulfur dioxides are titrated by the iodine and bromine liberated from the electrolysis of the potassium iodide and potassium bromide solution. The quantity of the electricity consumed by electrolysis is integrated and used to calculate the content of sulfur dioxides. The instrument is calibrated with certified reference materials. The percentage of total sulfur in the sample is calculated according to the sulfur dioxides content and the prior calibration.

ASTM D6045 Colorimeter Of Petroleum Products
KN-6045 Colorimeter for Petroleum Products conforms to the ASTM D6045 Standard Test Method for Color of Petroleum Products by the Automatic Tristimulus Method. Determination of the color of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic because color is readily observed by the user of the product. In some cases, the color may serve as an indication of the degree of refinement of the material. When the color range of a particular product is known, a variation outside the established range may indicate possible contamination with another product. However, color is not always a reliable guide to product quality and should not be used indiscriminately in product specifications.

ASTM D4530 Micro Carbon Residue Apparatus
The carbon residue value of the various petroleum materials serves as an approximation of the tendency of the material to form carbonaceous type deposits under degradation conditions similar to those used in the test method, and can be useful as a guide in manufacture of certain stocks. However, care needs to be exercised in interpreting the results
