Guidelines for the regeneration and use of phosphate ester hydraulic fluids
1 Scope
This document specifies the requirements for degradation classification, purification and regeneration, reuse after treatment, and scrap disposal of phosphate ester hydraulic fluids.
This document applies to the purification, regeneration and reuse of phosphate ester hydraulic fluid used in steam turbine electro-hydraulic speed control system and lubrication system. Other equipment
The phosphate ester hydraulic fluid used is implemented as per the reference.
