21、 Standardization) 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
22、right to 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.The procedu
23、res used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial
24、rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).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. Details of any patent rights ide
25、ntified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation

27、 ISO/TC 28, Petroleum products and related products of synthetic or biological origin.This third edition cancels and replaces the second edition (ISO 4263-3:2010). The main change is the revision of the calculation in Clause 9 to include calculations for both a test oil reaching a TAN of 2,0 mg KOH
28、per gram and for a test oil reaching an increase of TAN of 2,0 mg KOH per gram. In addition, the inclusion of HETG and exclusion of HFDR from the scope have been adopted.ISO 4263 consists of the following parts, under the general title Petroleum and related products Determination of the ageing behav

31、e ageing behaviour of inhibited oils and fluids using the TOST test Part 3: Anhydrous procedure for synthetic hydraulic fluidsWARNING 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 proble
32、ms 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 applicability of regulatory limitations prior to use.1 ScopeThis part of ISO 4263 specifies a method for the determination of the ageing be
33、haviour of synthetic hydraulic fluids of categories HFDU, HEES, HEPG and HETG as defined, for example, in ISO 129221and ISO 153802. 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.
34、 Other parts of ISO 4263 specify similar procedures 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 c
35、orrosion or change in viscosity, can occur which 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 may be used to compare the oxidation stability of fluids that
36、 are not prone to contamination with water. 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 synthe
37、tic hydraulic fluids is not known because interlaboratory 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.2 Normative referencesThe following documents, in whole or in part, are normativel

40、in the absence of light, at 95 C with oxygen and a steel and copper 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 either an acid number of 2,0 mg of potassium hydroxide ISO 2015 Al
41、l rights reserved 1BS EN ISO 4263-3:2015ISO 4263-3:2015(E)(KOH) per gram is reached or until an increase of 2,0 mg of potassium hydroxide (KOH) per gram of test portion is reached and the number of hours is recorded as the oxidation lifetime. For some requirements, the test may be discontinued at a
42、fixed number of hours (e.g. 500 h or 1 000 h) when the value of the acid number has still not either reached or increased by 2,0 mg of KOH per gram of test portion.4 Reagents and materials4.1 Water, unless otherwise specified, in accordance with the requirements of grade 2 of ISO 3696. Potable water
43、 means tap water, unless normal piped supplies are contaminated with particulate or high levels of soluble mineral content.4.2 Heptane, (C7H16),of minimum purity 99,75 %.4.3 Acetone, (CH3COCH3), of general purpose reagent grade (GPR).4.4 Propan-2-ol, (CH3CHOHCH3), of general purpose reagent grade (G
44、PR).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 regulation system and a needle valve to improve the consistency of gas-flow regul
45、ation.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 suspected, turn off immediately
46、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 alternative non-chromium containing solutions, such as ammonium persulfate
47、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 iron oxide deposits.WARNING Chromosulfuric acid is a health hazard. It is toxic
48、, 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 clothing are essential. Never pipette the cleaning solution by mouth. After use,
49、 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 to the environment).Strongly oxidizing acid cleaning solutions that are chromium-free are also highly corrosive and potentially hazardous in contact with organic materials, but do not contain chromium which has special disposal problems.4.6.2 Surfactant cleaning fluid.A proprietary st
