Get more information about the standard at ASTM D7418-23.
ASTM D7418 is a standard practice that outlines the setup and operational parameters for Fourier Transform Infrared (FT-IR) spectrometers used in monitoring the condition of in-service oils. This practice ensures consistent and reliable acquisition of FT-IR spectra from used oil samples, facilitating accurate assessments of lubricant health and machinery performance.
Details
This practice provides guidelines for configuring and operating FT-IR spectrometers to monitor in-service petroleum and hydrocarbon-based lubricants. It covers both direct trend analysis and differential (spectral subtraction) trend analysis approaches.
Operators are guided on how to collect FT-IR spectra from in-service oil samples using a standardized transmission cell. The practice emphasizes the importance of maintaining consistent instrument configurations and operating parameters to achieve comparable results across different instruments and laboratories.
