23、ndards 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 be represented on that committee. International or
24、ganizations, 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 Standards are drafted in accordance with the rules give
25、n 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 International Standard requires approval by at least 7
26、5 % 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 4263-4 was prepared by Technical Committee ISO/TC 28, Pe

28、: Anhydrous procedure for synthetic hydraulic fluids Part 4: Procedure for industrial gear oils EN ISO 4263-4:20061Petroleum and related products Determination of the ageing behaviour of inhibited oils and fluids TOST test Part 4: Procedure for industrial gear oils WARNING The use of this part of IS
29、O 4263 may 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 responsibility of the user of this part of ISO 4263 to establish appropriate safety and health practices and determine the
30、 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 gear oils of categories CKC, CKD, CKS and CKT as defined in ISO 6743-65. The ageing is accelerated by the presence of air and elevated temperatures
31、, and the degradation of the oil is assessed by the change in kinematic viscosity at 100 C, the insoluble content (precipitation number), and possibly the acid number increase, the sediment content by filtration, the additives content variation and the infra-red oxidation. 2 Normative references The

35、mination of density Oscillating U-tube methodEN ISO 4263-4:200623 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1insoluble content precipitation numbernumber of millilitres of precipitate formed when 10 ml of lubricating oil are mixed with 90 m
36、l of precipitation naphtha, and centrifuged under the conditions of the test 3.2sediment by filtration amount of insoluble matter, expressed in milligrams per 100 ml, retained on a filtration membrane of 1,2 mpore size after filtration under vacuum 4 Principle A test portion is reacted, in the absen
37、ce of light, in the presence of air, and at a temperature appropriate to the type of industrial gear oil under test: 95 C for CKC type; 121 C for CKD type; 150 C for CKS and CKT types. At the end of a 312 h period, the increase in kinematic viscosity at 100 C, the insoluble content (precipitation nu
38、mber), the increase in acid number (if required), the sediment content by filtration, the additives depletion and the infra-red oxidation, are determined. 5 Reagents and materials 5.1 Water, unless otherwise specified, in accordance with the requirements of grade 2 as defined in ISO 3696:1987. Potab
39、le water means tap water, unless normal piped supplies are contaminated with particulate or highly soluble mineral content. 5.2 Heptane (C7H16), of reagent grade and of minimum purity 99,75 %. 5.3 Acetone, (CH3COCH3), of general purpose reagent grade (GPR). 5.4 Air, dried, oil-free, at constant pres
40、sure. Supply from air cylinders or from a compressed air circuit is possible; this should be utilized via a regulation system to improve the consistency of the air flow. 5.5 Cleaning solutions 5.5.1 Strong oxidizing acid solution The reference strong oxidizing cleaning solution on which precision wa
41、s based, is chromosulfuric acid (see the following warning), but alternative non-chromium containing solutions, such as ammonium persulfate in concentrated sulphuric 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 p
42、art of orthophosphoric acid (concentrated GPR grade) removes iron 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 chromosulfu
43、ric acid cleaning solution, eye protection and protective clothing 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
44、with standard procedures for toxic laboratory waste (chromium is highly dangerous to the environment). EN ISO 4263-4:20063Strongly oxidizing acid cleaning solutions that are chromium-free are also highly corrosive and potentially hazardous in contact with organic materials, but do not contain chromi
45、um which has special disposal problems. 5.5.2 Surfactant cleaning fluid A proprietary strong surfactant cleaning fluid is a preferred alternative to the strong oxidizing cleaning solution whenever the condition of the glassware permits this. 5.5.3 Laboratory detergent The detergent shall be water so

The design and dimensions shall be as illus
47、trated in Figure 1. New corks should be used for each test. 6.2 Heating bath, consisting of a thermostatically controlled bath capable of maintaining the test oil portion in the oxidation cell at the specified temperature r 0,2 C. It shall be large enough to hold the required number of oxidation cel
48、ls (6.1) immersed in the heat-transfer medium so that the bath liquid is at least 50 mm above the level of the oil sample. It shall be constructed to ensure that light is excluded from the test portions during the test. If a fluid bath is used, it shall be fitted with a suitable stirring system to p
49、rovide a uniform temperature throughout the bath. If the fluid bath is fitted with a top, the total length of the oxidation cell within the bath shall be 390 mm r 10 mm. 6.3 Flowmeters, capable of measuring a flow of air of 10 l/h with an accuracy of r 0,5 l/h, one per oxidation cell is required. 6.4 Temperature-measurement devices 6.4.1 Heating bath. The temperature in liquid heating baths shall be measured by either a liquid-in-glass thermometer meeting the requirements of the specification
