Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Intemational organizations, governmental and non-g
6、overnmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters o f electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies f

13、which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibil

16、987, Petroleum products and lubricants - Petroleum oils and other fluids - Determination of rust-preventing characteristics in the presence of water. 3 Principle A test portion of grease is run in a specialized and carefully cleaned test rig under prescribed conditions for a total of 24 h, in three
17、separate 8 h periods, after introduction of an aqueous test fluid. At the end of the test period, the apparatus is dismantled and the condition of the outer ring track of the bearing is examined for corrosion and rated on an arbitrary scale. 4 Reagents and materials During the analysis, use only rea
18、gents of recognized analytical grade. 4.1 aromatic, low volatility hydrocarbon. Wash solvent, consisting of low-sulfur, low NOTE 1 White spirit to British Standard BS 245 or mineral spirit to ASTM D 235 (all classes) is suitable (see annex B). 4.2 Water, conforming to grade 3 of IS0 3696. NOTE 2 Wat
19、er as defined in 4.2 is used as a wash solvent but water quality in the test fluids (4.3) is critical, and for these a different grade is specified. 4.3 Test fluid. Use one of the following types: a) water conforming to grade 2 of IS0 3696, or b) synthetic sea water conforming to the specification g

21、 an 0,5 mol/l solution of sodium chloride prepared using water conforming to grade 2 of IS0 3696, at a pH o f 8,0 to 8,2, by titration with sodium hydroxide solution. NOTE 3 Other water types can be used in this test, although the precision when using other water types has not been determined. It is
22、 recommended that the pH of other water types is determined before use. 4.4 Propan-2-01. 4.5 Ammonia solution, 3,2 mol/l concentration. NOTE 4 The ammonia solution is equivalent to a tenfold dilution of 35 % ammonia solution (p = 880 kg/m3) with water conforming to grade 3 of IS0 3696. This ammonia
23、concentration is critical to the results of the test. 4.6 Solvent rinse solution, consisting of nine volumes of propan-2-01 (4.4) mixed with one volume of ammonia solution (4.5). 4.7 Silver nitrate solution, O, 1 mol/l concentration. 4.8 Cloth, absorbent, lint-free. 4.9 Protective gloves, smooth, cl
