ASTM D5837 Apparatus for Furanic Compounds by HPLC
KN-5837 Furanic Compounds by HPLC conforms to ASTM D5837 Standard Test Method for Furanic Compounds in Electrical Insulating Liquids by High-Performance Liquid Chromatography (HPLC). Furanic compounds are generated by the degradation of cellulosic materials used in the solid insulation systems of electrical equipment. Furanic compounds which are oil soluble to an appreciable degree will migrate into the insulating liquid. High concentrations or unusual increases in the concentrations of Furanic compounds in oil may indicate cellulose degradation from aging or incipient fault conditions.

ASTM D7419 HPLC for Total Aromatics and Total Saturates
KN-7419 HPLC for Total Aromatics and Total Saturates conforms to ASTM D7419 Standard Test Method for Determination of Total Aromatics and Total Saturates in Lube Basestocks by High Performance Liquid Chromatography (HPLC) with Refractive Index Detection. The composition of a lubricating oil has a large effect on the characteristics and uses of the oil. The determination of saturates, aromatics and polars is a key analysis of this composition. The characterization of the composition of lubricating oils is important in determining their interchangeability for use in blending etcetera.

ASTM D7525， ASTM D7545 Rapid Small Scale Oxidation Stability Tester
A 5ml sample is introduced into a vessel which is then charged with oxygen to 500kPa at a temperature of 15 to 25℃. The test is initiated by starting the heater and heating the pressure vessel to a temperature of 140℃. The pressure is recorded continuously until the breakpoint is reached. Alternatively, the test maybe terminated when a predetermined minimum requirement is reached.

ASTM D972 Evaporation Loss For Lubricating Grease
The loss of volatile materials from greases and oils can adversely effect the original performance characteristics of a lubricant and therefore could be a significant factor in evaluating a lubricant for a specific use. Such volatiles can also be considered contaminants in the environment in which the lubricant is to be used. Correlation between results from this test method and service performance has not been established.
