KN-4530 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 resultsRead

KN-323Z Automatic Reid Vapor Pressure Bath
Vapor pressure is an important physical property of volatile liquids. This test method is used to determine the vapor pressure at 37.8°C (100°F) of petroleum products and crude oils with initial boiling point above 0°C (32°F).
Vapor pressure is critically important for both automotive and aviation gasolines, affecting starting, warm-up, and tendency to vapor lock with high operating temperatures or high altitudes. Maximum vapor pressure limits for gasoline are legally mandated in some areas as aRead

KN-6079 Diesel Lubricating High Frequency Reciprocating Testing Machine(HFRR)
Diesel fuel injection equipment has some reliance on lubricating properties of the diesel fuel. Shortened life of engine components, such as diesel fuel injection pumps and injectors, has sometimes been ascribed to lack of lubricity in a diesel fuelRead

KN-5453 Ultraviolet Fluorescence Sulfur Tester
Some process catalysts used in petroleum and chemical refining can be poisoned when trace amounts of sulfur bearing materials are contained in the feedstocks. This test method can be used to determine sulfur in process feeds sulfur in finished products, and can also be used for purposes of regulatory control.Read

KN-7621 Apparatus for Hydrogen Sulfide in Fuel Oils
KN-7621 Apparatus for Hydrogen Sulfide in Fuel Oils conforms to ASTM D7621 Standard Test Method for Determination of Hydrogen Sulfide in Fuel Oils by Rapid Liquid Phase Extraction. A weighed test specimen is introduced into a heated test vessel containing a diluent base oil. Air is bubbled through the oil to extract the H2S gas. The air with the extracted H2S is passed, via a vapor phase processor (Procedure A only), to an H2S specific electro-chemical detector enabling the H2S content of the aiRead

KN-1500 Colorimeter for Petroleum Products
Determination of the color of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic, since 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 guideRead
