The work of preparing International Standards is normally carr
20、ied out through 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.
21、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 Internatio
22、nal 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 possibility that some of the elem
23、ents of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 4404-1 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants.This second edition cancels and replaces the first edition (ISO 4404-
24、1:2001), which has been technically revised.ISO 4404 consists of the following parts, under the general title Petroleum and related products Determination of the corrosion resistance of fire-resistant hydraulic fluids: Part 1: Water-containing fluids Part 2: Non-aqueous fluidsiv ISO 2012 All rights

It evaluates the corrosion protection provided by these fluids towards metal components used in hydraulic sy

33、lly submerged in the test fluid at a specific temperature and for a specific period. The change in mass of each test strip, its surface appearance and the change in the appearance of the fluid during the test are determined.NOTE 1 When assessing the corrosivity of HFAE and HFAS fluids, it may be nec
34、essary to dilute an additive concentrate with water and the quality of the water can significantly affect the test results. The diluent, therefore, needs to be chosen carefully and, preferably, to be representative of commercial use. The selection could be one of the test waters listed in Annex A, d
35、eionized water or mains water as agreed between the user and the fluid supplier.NOTE 2 The selection of the metals for corrosion testing may depend on the application and on the type of fluid being tested. For example, aluminium may not be used in mining applications while contact between HFC fluids
36、 and zinc shall be minimized as far as possible.5 Reagents and materials5.1 Acetone, analytical grade.5.2 Heptane, analytical grade.5.3 Water, selected from one of the following:a) a test water of composition specified in Annex A,b) deionized water conforming to grade 3 of ISO 3696:1987, orc) the su
