ASTM E2412 – 10(2018) Standard Practice for Condition Monitoring of In-Service Lubricants by Trend Analysis Using Fourier Transform Infrared (FT-IR) Spectrometry
The method of differential IR Fourier Spectrometry (analysis of working oil sample spectra as compared to the new oil sample spectra) allows to quickly control the state of engine oils in the process of operation.
Oils change their properties under the influence of loads, high temperatures and as a result of equipment wear – there is a depletion of additives, oxidation of basic components, water and fuel pollution, the accumulation of nitrogen and sulfur oxides. Negative changes in operating parameters of oils and greases lead to equipment failures.
IROS P01 IR Fourier spectrometer with liquid cell and
POilSpec software, with built-in graduation, allows to perform express analysis of working oil samples according to
ASTM E2412 – 10 standard.
