ASTM D2896 Base Number Of Petroleum Products
New and used petroleum products can contain basic constituents that are present as additives. The relative amounts of these materials can be determined by titration with acids. The base number is a measure of the amount of basic substance in the oil, always under the conditions of the test. It is sometimes used as a measure of lubricant degradation in service; however, any condemning limits must be empirically established.

ASTM D924 Dielectric Dissipation Factor Tester
Dissipation Factor (or Power Factor)—This is a measure of the dielectric losses in an electrical insulating liquid when used in an alternating electric field and of the energy dissipated as heat. A low dissipation factor or power factor indicates low ac dielectric losses. Dissipation factor or power factor may be useful as a means of quality control, and as an indication of changes in quality resulting from contamination and deterioration in service or as a result of handling.

KN-NIR Near Infrared Spectrometer
KN-NIR Near Infrared Spectrometer adopts advanced MEMS Fourier transform technology. Optional spectral range of the instrument (1300nm~2600nm, 1150~1700nm, 1250~2100nm) meets the needs in testing multiple indicators and research. High signal to noise ratio is possible to analyze the parameters of low content of the sample. Built in wavelength calibration to ensure smaller difference between stations difference and better long-term stability. The tester equipped with a temperature control device, which can improve the data stability.

ASTM D613 Cetane Number of Diesel Fuel Oil
The cetane number of a diesel fuel oil is determined by comparing its combustion characteristics in a test engine with those for blends of reference fuels of known cetane number under standard operating conditions. This is accomplished using the bracketing handwheel procedure which varies the compression ratio (handwheel reading) for the sample and each of two bracketing reference fuels to obtain a specific ignition delay permitting interpolation of cetane number in terms of handwheel reading.
