SH/T 0935-2016 in English

This standard provides a method for the monitoring of the sulfation condition of used petroleum-based and hydrocarbon-based lubricating oils using Fourier transform infrared spectroscopy (FT-IR) trend analysis. It outlines the procedures for sample preparation, data acquisition, and interpretation of spectral data to assess the condition of the oils. The method is designed to support trend analysis, enabling the detection of early signs of degradation or contamination. The standard specifies the equipment requirements, calibration procedures, and analytical techniques necessary for accurate and consistent results. It also includes guidelines for the storage and handling of samples to ensure the integrity of the data obtained. The method is applicable for routine monitoring in industrial and maintenance settings.
