Scope

ISO 11158:2009 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 ISO 11158:2009 is for the guidance of suppliers and end users of mineral oil hydraulic fluids and for the direction of equipment manufacturers of hydraulic systems.
ISO 11158:2009 is written in a general form so that its application can accommodate various climatic conditions throughout the world. ISO 11158:2009 also stipulates the requirements for mineral-oil hydraulic fluids at the time of delivery.
