Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 YO of the member bodies casting
a vote.
International Standard IS0 11 158 was prepared by Technical Committee
lSO/TC 28, Petroleum products and lubricants, Subcommittee SC 4,
Classifications and specifications.
Annexes A and B of this International Standard are for information only.

WARNING - The handling and use of products as specified in this International Standard
may be hazardous, if suitable precautions are not observed. This International Standard
does not purport to address all of the safety problems associated with its use. It is the
responsibility of the user of this standard to establish appropriate safety and health
practices and determine the applicability of regulatory limitations prior to use.
1 Scope
This International Standard specifies the requirements of mineral oil hydraulic fluids and is
intended for hydraulic systems, particularly for hydrostatic hydraulic fluid power application. The
purpose of this International Standard is for the guidance of suppliers and end users of mineral oil
hydraulic fluids and for the direction of equipment manufacturers of hydraulic systems.
This International Standard is written in a general form so that its application can accommodate
various climatic conditions throughout the world. This International Standard also stipulates the
requirements of mineral oil hydraulic fluids at the time of delivery.
Classification of fluids used in hydraulic applications is defined in IS0 6743-4. Of the categories
IS0 6743-4, six types only of mineral oil based fluids are embraced in this
covered by
specification. These categories are: HH, HL, HM, HR, HV and HG.
NOTE - Although specifications given in this International Standard refer only to mineral oil based hydraulic
fluids, this specification can be applicable to certain types of hydrocarbon synthetic fluids e.g. polyalphaolefin
(type HS).
