The work of preparing International
23、Standards is normally carried 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, al
24、so 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 committ
25、ees 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 poss
26、ibility that some of the elements 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 4263-3 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants. This second edition cancels and replac
27、es the first edition (ISO 4263-3:2006), of which it is a minor revision with changes to the title, Clause 3 (last sentence), 8.8, 8.9 and 10.1 plus some minor editorial modifications. ISO 4263 consists of the following parts, under the revised general title Petroleum and related products Determinati

31、ing the TOST test Part 3: Anhydrous procedure for synthetic hydraulic fluids WARNING The use of this part of ISO 4263 can involve hazardous materials, operations and equipment. This part of ISO 4263 does not purport to address all of the safety problems associated with its use. It is the responsibil
32、ity of the user of this part of ISO 4263 to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1 Scope This part of ISO 4263 specifies a method for the determination of the ageing behaviour of synthetic hydraulic fluids of catego
33、ries HFDR, HFDU, HEES and HEPG as defined, for example, in ISO 129224and ISO 153805. The ageing is accelerated by the presence of oxygen and metal catalysts at elevated temperature, and the degradation of the fluid is followed by changes in acid number. Other parts of ISO 4263 specify similar proced
34、ures for the determination of ageing behaviour of mineral oils and specified categories of fire-resistant fluids used in hydraulic and other applications. NOTE Other signs of fluid deterioration, such as the formation of insoluble sludge, catalyst coil corrosion or decrease in viscosity, can occur w
35、hich indicate oxidation of the fluid, but are not reflected in the calculated oxidation lifetime. The correlation of these occurrences with field service is under investigation. This test method can be used to compare the oxidation stability of fluids that are not prone to contamination with water.
36、However, because of the large number of individual field-service applications, the correlation between the results of this test and actual service performance can vary markedly, and is best judged on experience. The precision of this test method for synthetic hydraulic fluids is not known because in
37、terlaboratory data are not available. This method might not be suitable for use in specifications or in the event of disputed results as long as these data are not available. However, precision for inhibited turbine oils is given in Clause 11 for guidance as an indication of the precision that could
38、 be obtained for synthetic hydraulic fluids. 2 Normative references The following referenced documents are indispensable for the application of this document.

41、pper catalyst coil. Small aliquots of the fluid are withdrawn at regular intervals and the acid number is measured (see the Note in Clause 1). The test is continued until an acid number increase of 2,0 mg of potassium hydroxide (KOH) per gram of test portion is reached and the number of hours is rec
42、orded as the oxidation lifetime. For some requirements, the test may be discontinued at a fixed number of hours (e.g. 500 h or 1 000 h) when the value of the acid number has still not increased by 2,0 mg of KOH per gram of test portion. 4 Reagents and materials 4.1 Water, unless otherwise specified,
43、 in accordance with the requirements of grade 2 of ISO 3696:1987. Potable water means tap water, unless normal piped supplies are contaminated with particulate or highly soluble mineral content. 4.2 Heptane (C7H16), of minimum purity 99,75 %. 4.3 Acetone (CH3COCH3), of general purpose reagent grade
44、(GPR). 4.4 Propan-2-ol (CH3CHOHCH3), of general purpose reagent grade (GPR). 4.5 Oxygen, of minimum purity 99,5 %, supplied through a pressure-regulation system adequate to maintain the specified flow rate throughout the test duration. Supply from an oxygen cylinder should be via a two-stage regulat
45、ion system and a needle valve to improve the consistency of gas-flow regulation. WARNING Use oxygen only with equipment validated for oxygen service. Do not allow oil or grease to come into contact with oxygen and clean and inspect all regulators, gauges and control equipment. Check the oxygen-suppl
46、y system regularly for leaks. If a leak is suspected, turn off immediately and seek qualified assistance. 4.6 Cleaning solutions 4.6.1 Strong oxidizing acid solution The reference strong oxidizing cleaning solution on which precision was based, is chromosulfuric acid (see the following warning), but
47、 alternative non-chromium containing solutions, such as ammonium persulfate in concentrated sulfuric acid (8 g/l), have been found to give satisfactory cleanliness. A 10 % solution of three parts of hydrochloric acid (1 mol/l) and one part of orthophosphoric acid (concentrated GPR grade) removes iro
48、n oxide deposits. WARNING Chromosulfuric acid is a health hazard. It is toxic, a recognized carcinogen as it contains Cr(VI) compounds, highly corrosive and potentially hazardous in contact with organic materials. When using a chromosulfuric acid cleaning solution, eye protection and protective clot
49、hing are essential. Never pipette the cleaning solution by mouth. After use, do not pour cleaning solution down the drain, but neutralize it with great care owing to the concentrated sulfuric acid present, and dispose of it in accordance with standard procedures for toxic laboratory waste (chromium is highly dangerous
