26、ional Organization for Standardization) is a worldwide federation of national standards bodies(ISO member bodies). The work of preparing International Standards is normally carried out through ISOtechnical committees. Each member body interested in a subject for which a technical committee has beene
27、stablished has the right to be represented on that committee. International organizations, governmental andnon-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the InternationalElectrotechnical Commission (IEC) on all matters of electrotechnical standardiz
28、ation.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 Standardsadopted by the technical committees are circulated to the member bodies for voting.
29、 Publication as anInternational Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patentrights.

31、 The use of this International Standard may involve hazardous materials, operations andequipment. This International Standard does not purport to address all of the safety problemsassociated with its use. It is the responsibility of the user of this International Standard to establishappropriate saf
32、ety and health practices and determine the applicability of regulatory limitations prior touse.1ScopeThis International Standard specifies procedures for the determination of steel-on-steel anti-wear properties ofhydraulic fluids by means of performance in a vane-type hydraulic pump. It covers a ran
33、ge of hydraulic fluids,both anhydrous and aqueous, intended for applications where high-speed sliding contacts, such as those foundin a vane pump, are encountered.For mineral oils of categories HM and HV, and fire-resistant fluids of category HFD, the method is applicable toviscosity classes ISO VG
34、32, ISO VG 46 and ISO VG 68, as specified in ISO 34481. Under different specifiedconditions, the method is applicable to aqueous fire-resistant hydraulic fluids in categories HFA, HFB and HFC,as specified in ISO 129223, within the same viscosity classes.NOTE Viscosity classes below ISO VG 32 and abo
35、ve ISO VG 68 can be tested by this technique, but require differentconditions of pump inlet viscosity, and have not been widely assessed. This International Standard is confined to thespecified limiting values defined.2 Normative referencesThe following referenced documents are indispensable for the
