This document specifies the minimum requirements for new mineral oil hydraulic fluids and is intended for hydraulic systems, particularly for hydrostatic hydraulic fluid power application. The purpose of this document is to guide suppliers and end users of mineral oil hydraulic fluids and to direct equipment manufacturers of hydraulic systems.

This document is written in a general form so that its application can accommodate various climatic conditions. This document also stipulates the requirements for mineral-oil hydraulic fluids at the time of delivery.
