7、ISO 2003 All rights reserved ISO 4404-2:2003(E) ISO 2003 All rights reserved iii Foreword ISO (the International 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
8、 ISO 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. ISO collaborate
9、s 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
10、. 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 possibility that some of the elements of this
11、 document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 4404-2 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants. ISO 4404 consists of the following parts, under the general title Petroleum and

13、n resistance of fire-resistant hydraulic fluids Part 2: Non-aqueous fluids WARNING The use of this International Standard may involve hazardous materials, operations and equipment. This International Standard does not purport to address all of the safety problems associated with its use. It is the r
14、esponsibility of the user of this International Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1 Scope This part of ISO 4404 specifies a procedure for the determination of the corrosion-inhibiting properties of no
15、n- aqueous hydraulic fluids within the category HFD, as classified in ISO 6743-4. It provides a qualitative assessment of corrosion of five of the most common metals used in the construction of hydraulic systems, but other metals and/or alloys could be added or substituted for these metals for parti
16、cular installations. NOTE The determination of corrosion resistance of aqueous hydraulic fluids within categories HFA, HFB and HFC is described in ISO 4404-1. 2 Normative references The following referenced documents are indispensable for the application of this document.

19、ly and in pairs, in the test fluid for 672 h at 35 C. At the end of the test period, the change in mass of the test piece is recorded and the appearance of both the test pieces and test fluid is assessed against arbitrary classification scales. 4 Reagents and materials 4.1 Heptane, commercial grade.
20、 4.2 Toluene, conforming to the requirements of grade 2 of ISO 5272. 4.3 Abrasive cloth or paper, made of silicon carbide, of nominal grit sizes 125 m, 65 m, 37 m and 26 m. NOTE Papers and cloths are often sold against arbitrary grit sizes. The above represent P 120, P 240, P 400 and P 600 respectiv
