motor oil

Industrial machinery; Industrial lubricants

Oil that is used to lubricate the moving components of an internal-combustion engine.

multigrade oil

Industrial machinery; Industrial lubricants

An oil meeting the requirements of more than one SAE viscosity grade classification, and may therefore be suitable for use over a wider temperature range than a single-grade oil.

infrared spectroscopy

Industrial machinery; Industrial lubricants

An analytical method using infrared absorption for assessing the properties of used oil and certain contaminants suspended therein. See FTIR.

infrared spectra

Industrial machinery; Industrial lubricants

A graph of infrared energy absorbed at various frequencies in the additive region of the infrared spectrum. The current sample, the reference oil and the previous samples are usually compared.

infrared analysis

Industrial machinery; Industrial lubricants

A form of absorption spectroscopy that identifies organic functional groups present in a used oil sample by measuring their light absorption at specific infrared wavelengths; absorbance is ...
