Petroleum and related products - Determination of the ageing behaviour of inhibited oils and fluids - TOST test - Part 3: Anhydrous procedure for synthetic hydraulic fluids (ISO 4263-3:2006)

This standard outlines a method for determining the ability of oils and related products to inhibit oxidation and fluid aging, specifically focusing on synthetic hydraulic fluids in a water-free environment. The procedure is designed to assess the oxidative stability of these fluids under controlled conditions. The test involves subjecting the fluid to a combination of heat, oxygen, and mechanical stress to simulate real-world operational conditions. The results provide valuable information on the fluid's performance and longevity. The method is based on established international guidelines and is intended for use in quality control and product development processes. The test conditions and procedures are clearly defined to ensure consistency and repeatability across different laboratories.
