Tests on lubricating oils can be broadly divided into chemical and physical tests ;
Physical Tests include :
Density
Viscosity
Colour (Appearance)
Flash Point
Lubricity
Wear tests (eg 4 Ball, Timken, etc)
Chemical Tests include :
Estimation of additive levels - eg metals (typ Zn, Ca, Mg, Na and wear metals) by AAS or ICP or quantitative FTIR, phosphorous, sulphated ash
Total Acid and Total Base number by titration
Water Content by distillation, titration or quantitative IR/FTIR
Copper Strip / Silver Strip test (used to determine corrosivity)
Determination of aromaticity by chromatography (GC / GCMS)
For a more complete list try the ASTM guidelines for analysis of petroleum products.

There are several types of chemical analysis, including qualitative analysis, quantitative analysis, instrumental analysis, and spectroscopic analysis. These methods are used to determine the composition, structure, and properties of substances.
What specific properties of a substance can be determined by conducting a chemical analysis, and what methods can be used to perform this analysis Ask a chemist for expert advice.?
Chemical analysis can determine properties such as composition, purity, and concentration of a substance. Methods like spectroscopy, chromatography, and titration are commonly used for this purpose. Consulting a chemist for expert advice on specific techniques and interpretation of results is recommended.
What is semimicro analysis?
Semimicro analysis is a method of chemical analysis that involves using smaller quantities of substances (typically 1-10 milligrams) compared to conventional methods. It is useful for analyzing trace amounts of substances and is commonly used in qualitative and quantitative analysis in chemistry laboratories.
How are you able to find the concentration of a chemical in water?
The concentration of a chemical in water can be found using various methods such as spectrophotometry, titration, or chromatography. These methods involve measuring the absorbance, volume, or separation of the chemical in water to calculate its concentration. accurate measurements and proper calibration are essential for determining the concentration of a chemical in water.
What are the main lubricants used in forging?
Lubricants used are oil, graphite, water and synthetic lubricants.
What methods can be used for predicting the solubility of organic compounds?
Various methods can be used to predict the solubility of organic compounds, including quantitative structure-activity relationships (QSAR), molecular modeling, and experimental data analysis. These methods involve analyzing the chemical structure of the compound and its interactions with solvents to estimate its solubility.
What is application of nuclear magnetic resonance in engineering?
It would be used in any branch of engineering involving the analysis of chemicals, such as chemical engineering, petroleum engineering etc. It could also be used to indentify various lubricants or fuels used by engineers, but it's mostly an analytical chemist would carry out the tests.
What are the methods used to predict products of chemical reactions?
