29、dization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International 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
30、 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 Stan
31、dards 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 Int
32、ernational 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 patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 4263-
33、1 was prepared by Technical Committee ISO/TC 28, Petroleum products and lubricants. ISO 4263 consists of the following parts, under the general title Petroleum and related products Determination of the ageing behaviour of inhibited oils and fluids TOST test: Part 1: Procedure for mineral oils Part 2
34、: Procedure for category HFC hydraulic fluids Part 3: Anhydrous procedure for synthetic hydraulic fluids Part 4: Procedure for industrial gear oils EN ISO 42631:2004 Licensed Copy: sheffieldun sheffieldun, na, Sun Nov 19 15:38:36 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 1 Petroleum and related pro
35、ducts Determination of the ageing behaviour of inhibited oils and fluids TOST test Part 1: Procedure for mineral oils WARNING The use of this part of ISO 4263 may involve hazardous materials, operations and equipment. This part of ISO 4263 does not purport to address all of the safety problems assoc
36、iated with its use. It is the responsibility 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 behaviou
37、r of rust- and oxidation- inhibited mineral oils having a density less than that of water, used as turbine oils (categories TSA, TGA, TSE, TGE of ISO 6743-5, see 4 in the Bibliography), hydraulic oils (categories HL, HM, HR, HV, HG of ISO 6743-4, see 3 in the Bibliography), and circulating oils (cat
38、egory CKB of ISO 6743-6, see 5 in the Bibliography). Oils containing synthetic components can be tested by this procedure, but no precision statement is available yet for such fluids. NOTE 1 For the purposes of this part of ISO 4263, the term “% (m/m)“ is used to represent the mass fraction of a mat
39、erial. NOTE 2 Other signs of oil deterioration, such as the formation of insoluble sludge, catalyst coil corrosion or decrease in pH value, may occur, which indicate oxidation of the oil, but are not reflected in the calculated oxidation lifetime. The correlation of these occurrences with field serv
40、ice is under investigation. This test method is widely used in specifications and is considered of value in comparing the oxidation stability of oils that are prone to contamination with water. However, because of the large number of individual field- service applications, the correlation between th
41、e results of this test and actual service performance can vary markedly, and is best judged on experience. The precision of this part of ISO 4263 for oxidation life was only determined on inhibited turbine oils, and applies to oxidation lives of 700 h to 3 900 h. 2 Normative references The following

45、 is reacted, in the absence of light, at 95 C with oxygen in the presence of water and a steel and copper catalyst coil. Small aliquots of the oil are withdrawn at regular intervals and the acid number is measured (see Note 2 in Clause 1). The test is continued until an acid number of 2,0 mg of pota
46、ssium hydroxide (KOH) per gram of test portion is reached and the number of hours is recorded as the oxidation life. For some requirements, the test may be discontinued at a fixed number of hours (e.g. 1 000 h) when the value of the acid number is still below 2,0 mg of KOH per gram of test portion.
47、4 Reagents and materials 4.1 Water, unless otherwise specified, in accordance with the requirements of grade 2 as defined in ISO 3696. Potable water means tap water, unless normal piped supplies are contaminated with particulate or highly soluble mineral content. 4.2 Heptane (C7H16), of minimum puri
48、ty 99,75 %. 4.3 Acetone (CH3COCH3), of general purpose reagent grade (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 durat
49、ion. Supply from an oxygen cylinder should be via a two-stage regulation 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-supply system regularly for leaks. If a leak is
