  • Base number of diesel engine Testing a lubricant's base number measures its alkaline reserve - or its ability to neutralize degradation acids. Although viscosity is most important, base number determines an oil's suitability for continued use and is critical to safely extending drain intervals. A decrease in base number is typically ...
  • Total Base Number (TBN) Total Base Number(TBN) is a measure of reserve alkaline additives put into lubricants to neutralize acids, to retard oxidation and corrosion, enhance lubricity, improve viscosity characteristic and reduce the tendency of sludge buildup. Simply put, it is a test to measure the ability to neutralize corrosive ...
  • Using conditions of Acid Number Tester KL632 1. Environmental temperature : 20℃ - 40℃2. Relative humidity : < 75%3. Concentration of neutral fluid: 0.02-0.03mol/L (Test oil type pH value ＜ 0.01mgKOH/g) 0.03-0.05mol/L (Test oil type pH value ＞ 0.01mgKOH/g)
  • Color Determination Methods Tristimulus MethodCovers the automatic determination of the color according to ASTM & Saybolt Color Scale Method ASTM ColorFor a wide range of petroleum products, including lubricating oils, heating oils, diesel oils, insulating oils etc. Saybolt ColorFor colorless to slightly yellowish petroleum ...
  • Color Determination Instrument Using Scope The using scope of color determination instrument includes aviation fuel, benzene, biodiesel, biofuel, chemicals, diesel, dyes, engine oil, fuel, gasoline, hydraulic fluid, insulating oil, transformer oil, jet fuel, jet lube, kerosene, light oil, lubricating oil, mineral oil, naphtha, solvent, turbine ...
  • Functions of Saybolt Color The function of Saybolt Color is to control manufacturing quality of oil. The color is an important quality characteristic of oil, and is easily for user's observation. Under some conditions, the color may serve as an indication of the degree of refinement. For some oil which the color range is known, ...
  • Saybolt Color of Petroleum Products Saybolt color --- an empirical definition of the color of a clear petroleum liquid based on a scale of -16 (darkest) to +30 (lightest). The number is derived by finding the height of a column of the sample that, when viewed through the length of the column, visually matches the appropriate one of three ...
  • SAE Viscosity Ratings SAE viscosity ratings in order of preference from best to worst:The best possible: SAE 0W-60 (Very expensive)The best available: SAE 5W-50 (Possible only with fully synthetic motor oil)2nd best: SAE 5W-40 for colder climates (Synthetic or Blend) SAE 10W-50 for warmer climates (Synthetic ...
  • Which SAE viscosity rating is the best? SAE 0W-60 is the best but it is now not available.Theoretically the best possible SAE viscosity rating is 0W-60, but only small experimental quantities of such lubricants were ever produced. The NASA SynLube is rated SAE 0W-60, but it sells for USD95 per liter, therefore it is not economical or practical ...
  • SAE and ISO viscosity classification system SAE --- The Society of Automotive Engineers is an engineering society founded to develop, collect, and disseminate knowledge of mobility technology.ISO viscosity classification system, approved by the International Standards Organization, for classifying industrial lubricants according to viscosity. ...
