Depends on how complex you want to get and what type of oil (engine, hydraulic, transmission, etc), but basically :
Viscosity vs standard range (40°C/100°C/VI)
Appearance
Odour
Oxidation by IR
Fuel Dilution - either by GC or flashpoint
Wear metals - AAS / ICP
Water - "crackle test"/ Karl Fischer / IR or "Dean & Stark" distillation
Particulates - filtration, hexane insolubles or IR
Residual TBN (Total Base Number) for engine oils or TAN (Total Acid Number) as an indicator of oxidation in hydraulic oils
Demulsibility (the oil's ability to separate water) - Turbine oils
Unsulphonatable residue - Medicinal White Oils and some agricultural oils

How do you check they purity of herione?
The purity of heroin can be checked using chemical testing methods, such as gas chromatography or mass spectrometry. These tests analyze the composition of the substance to determine the percentage of heroin present and detect any potential adulterants or contaminants. It is important to use these tests for harm reduction purposes and to ensure the safety of individuals using the drug.
How to test the purity of deionized water?
To test the purity of deionized water, you can use a conductivity meter to measure the electrical conductivity. The lower the conductivity, the purer the water. Additionally, you can use a Total Organic Carbon (TOC) analyzer to check for organic impurities. Conducting these tests will help determine the purity of deionized water.
How can you check the purity of BaSO4 crystals?
The purity of BaSO4 crystals can be checked using techniques such as X-ray diffraction to determine the crystal structure, elemental analysis to measure the composition, and methods like infrared spectroscopy or UV-Vis spectroscopy to identify impurities in the crystal lattice. Additional tests like melting point determination or specific surface area measurements can also provide information about the purity of the crystals.
What are the different ways to test the purity of water?
There are several methods to test the purity of water, including chemical tests, physical tests, and biological tests. Chemical tests involve analyzing the levels of specific substances in the water, such as pH, dissolved solids, and contaminants. Physical tests measure properties like turbidity, temperature, and odor. Biological tests assess the presence of bacteria and other microorganisms in the water. These tests help determine if the water is safe for drinking and other uses.
What is the purpose of a purity test?
Purity tests are used to determine the extent to which a particular substance is what is claimed. A classic purity test for gold is nitric acid; if the item being examined reacts to the acid it is not gold, or at least not pure gold.
What is purity testing of microorganisms?
purity testing of microorganism is to check weahter the microbial culture contain one type of cells of species or it get contaminated or mixed with other type.the best way to check this is by sub culturing and staining.
Why do you check the conductivity of liquids?
Sometime it is needed to check purity of a liquid, to check metal content of a liquid.
What measures are in place to ensure the purity of methamphetamine in the production process?
In the production process of methamphetamine, measures such as using high-quality chemicals, following strict manufacturing protocols, and conducting purity tests are in place to ensure the quality and purity of the final product.
How do you check the purity of pure wool?
Your answer depends on the purpose of your test.
What tests are there to check for HIV?
Can i test
How do you check a chemical for purity?
Chemical analysis is used to test the purity of materials. We know today a very great number of analysis methods.
Is oil a translucent liquid?
No, oil is typically not translucent but opaque. It has a yellowish, brownish, or greenish hue, and its opacity can vary depending on the type and purity of the oil.
