Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies).Each The member work of preparing International Standards is normally carried out through ISO technical committees. 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. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. 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 % of the member bodies casting a vote. Attention is drawn to the possibilit possibility y that some of the elements of this document docum ent m may ay be the subject of pate patent nt rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 11158 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants, lubricants , Subcommittee SC 4, Classifications and specifications. specifications. This second edition cancels canc els and replaces the first edition (ISO 11158:1997), which has been bee n technically revised.

INTERNATIONAL INTERNATIO NAL STANDARD
ISO 11158:2009(E)
Lubricants, industrial oils and related products (class L) — Family H (hydraulic systems) — Specifications for categories HH, HL, HM, HV and HG
WARNING — The handling and use of products as specified in this International In ternational Standard can 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 International Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
1
Scope
This International Standard 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 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 for mineral-oil hydraulic fluids at the time of delivery. Classification of fluids used in hydraulic applications is defined in ISO 6743-4. Of the categories covered by ISO 6743-4, only five types of mineral oil based fluids are covered in this International Standard. T These hese categories are HH, HL, HM, HV and HG.

Cleanliness Cleanliness level level expressed according to ISO 4406 may be established by agreement between the supplier and the end-user. It should be noted that the fluid is exposed to various influences during transport and storage; the cleanliness level required for the system should be guaranteed by careful filtering of the hydraulic fluid when filling. g
Initial acid acid number number is influenced by the presence of functional functional moieties in the additive package.
h The definition of compatibility for types of elastomers elastomers other than NBR 1 (e.g. FPM, EPDM, AU) may be agreed between the supplier and the end users. i
There are currently no pre precision cision da data ta for the method method when non-Eaton/Vickers test cartridges [e.g. Conestoga Conestoga USA, Inc.4) and Tokimec4)] are used. Consequently, no absolute mass loss limits can be stipulated until the precision of V104C pump cartridges from the new supplier has been determined. In the interim, the limits previously established for Eaton/Vickers cartridges may be used for guidance. It should be noted that ISO 20763 supersedes BS 2000: Part 281, IP 281 and DIN 51389 (all parts). For fluids evaluated under the aforementioned methods, the test data are considered to remain valid and no re-testing against ISO 20763 is required. j
AFNOR XP T 60-183 60-183 tribometer test method, or any other suitable suitable method agreed with the supplier supplier and /or the end-user, may be used to demonstrate
the frictional properties of the oil, and the absence of stick-slip phenomena (steel/steel contact).
