1 Scope This document specifies the requirements for environmentally acceptable hydraulic fluids and is intended for hydraulic systems, particularly hydraulic fluid power systems. The purpose of this document is to provide guidance and requirements for suppliers and users of environmentally acceptable hydraulic fluids, and for the direction of original equipment manufacturers of hydraulic systems. This document stipulates the requirements for environmentally acceptable hydraulic fluids at the time of delivery. Classification of fluids used in hydraulic application is defined in ISO 6743‑4. This document encompasses the four categories of environmentally acceptable fluids covered by ISO 6743‑4, namely HETG (triglycerides), HEPG (polyglycols), HEES (synthetic esters) and HEPR (polyalphaolefins and other synthetic hydrocarbons).
