25、deration 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 be represented on that com
26、mittee. 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 Standards are drafted in accord
27、ance 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 International Standard require
28、s 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 4263-4 was prepared by Technical
29、 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: Procedure for category

31、 the ageing behaviour of inhibited oils and fluids TOST test Part 4: Procedure for industrial gear 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 associated with its
32、 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 behaviour of gear oils
33、 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, 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 nu
34、mber increase, the sediment content by filtration, the additives content variation and the infra-red oxidation. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated referenc
35、es, the latest edition of the referenced document (including any amendments) applies.

38、d Copy, (c) BSI 2 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 insoluble content precipitation number number of millilitres of precipitate formed when 10 ml of lubricating oil are mixed with 90 ml of precipitation naphtha, and centrifuged
39、under the conditions of the test 3.2 sediment by filtration amount of insoluble matter, expressed in milligrams per 100 ml, retained on a filtration membrane of 1,2 m pore size after filtration under vacuum 4 Principle A test portion is reacted, in the absence of light, in the presence of air, and a
40、t 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 number), the increase in acid number (if req
41、uired), 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. Potable water means tap water, unless normal pi
42、ped 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 pressure. Supply from air cylinders or from a
43、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 was based, is chromosulfuric acid (see the f
44、ollowing 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 part of orthophosphoric acid (concentrated
45、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 chromosulfuric acid cleaning solution, eye protection
46、 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 with standard procedures for toxic laborat
47、ory waste (chromium is highly dangerous to the environment).

48、ardous in contact with organic materials, but do not contain chromium 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 permi

The design and dimensions shall be as illustrated in Figure 1. New corks should be used for each test. 6.2 Heati
