Contaminants monitored include water, soot, ethylene glycol, fuels and incorrect oil. Oxidation, nitration and sulfonation of base stocks are monitored as evidence of degradation. The objective of this monitoring activity is to diagnose the operational condition of the machine based on fault conditions observed in the oil.<a class=\"partenaire\" href=\"https:\/\/normalab.com\/partenaires\/#eralytics\">Eralytics<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Standard Practice for Condition Monitoring of In-Service Lubricants by Trend Analysis Using Fourier Transform Infrared (FT-IR) Spectrometry<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":3231,"menu_order":0,"template":"","meta":{"_acf_changed":false},"groupe-norme":[105],"class_list":["post-4390","normes","type-normes","status-publish","hentry","groupe-norme-astm-en"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.9 -
