21、ICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 603: Physical tests Measurement of total acid number of filling compounds FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees

22、 (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Repo

23、rts, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and n

24、on-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements

25、of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are

26、 accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote inter

27、national uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in t

28、he latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All user

29、s should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or othe

30、r damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. U

31、se of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent

32、 rights. International Standard IEC 60811-603 has been prepared by IEC technical committee 20: Electric cables. This Part 603 of IEC 60811 cancels and replaces Clause 7 of IEC 60811-5-1:1990, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. There are n

33、o specific technical changes with respect to the previous edition, but see the Foreword to IEC 60811-100:2012. 4 60811-603 IEC:2012 The text of this standard is based on the following documents: FDIS Report on voting 20/1312/FDIS 20/1361/RVD Full information on the voting for the approval of this st

34、andard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This part of IEC 60811 shall be used in conjunction with IEC 60811-100. A list of all the parts in the IEC 60811 series, published under the

35、general title Electric and optical fibre cables Test methods for non-metallic materials, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the

36、data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60811-603 IEC:2012 5 INTRODUCTION The IEC 60811 series specifies the test methods to be used for testing non-metallic materials of all types of cables. T

37、hese test methods are intended to be referenced in standards for cable construction and for cable materials. NOTE 1 Non-metallic materials are typically used for insulating, sheathing, bedding, filling or taping within cables. NOTE 2 These test methods are accepted as basic and fundamental and have

38、been developed and used over many years principally for the materials in all energy cables. They have also been widely accepted and used for other cables, in particular optical fibre cables, communication and control cables and cables for ships and offshore applications. 6 60811-603 IEC:2012 ELECTRI

39、C AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 603: Physical tests Measurement of total acid number of filling compounds 1 Scope This Part 603 of IEC 60811 gives the test methods to examine the filling compound for corrosive elements. 2 Normative references The following doc

40、uments, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60811-100:2012, Elec

41、tric and optical fibre cables Test methods for non-metallic materials Part 100: General 3 Terms and definitions For the purposes of this document, the terms and definitions given in IEC 60811-100 apply. 4 Test method 4.1 General This part of IEC 60811 shall be used in conjunction with IEC 60811-100.

42、 Unless otherwise specified, tests shall be carried out at room temperature. This test is used to examine the filling compound for corrosive elements. The total acid number is defined as the quantity of base, expressed in milligrams of potassium hydroxide (KOH), that is required to titrate all acidi

43、c constituents present in 1 g of sample. 4.2 Apparatus The apparatus comprises a 50 ml burette graduated in 0,1 ml subdivisions or a 10 ml burette graduated in 0,05 ml subdivisions. 4.3 Reagents 4.3.1 General The reagent shall be of an analytical reagent quality. Distilled water shall be used throug

44、hout. 60811-603 IEC:2012 7 4.3.2 Potassium hydroxide solution, standard alcoholic (0,1 N) Add 6 g of solid KOH to approximately 1 l of anhydrous isopropyl alcohol (containing less than 0,9 % water) in a 2 l Erlenmeyer flask. Boil the mixture gently for 10 min to 15 min, stirring to prevent the solid

45、s from forming a cake on the bottom. Add at least 2 g of barium hydroxide (Ba(OH)2) and again boil gently for 5 min to 10 min. Cool to room temperature, allow to stand for several hours, and filter the supernatant liquid through a fine sintered glass or porcelain filtering funnel. Avoid unnecessary

46、exposure to carbon dioxide (CO2) during filtration. Store the solution in a chemically resistant dispensing bottle out of contact with cork, rubber or saponifiable stopcock lubricant and protected by a guard tube containing soda, lime or soda asbestos. Standardize frequently enough to detect changes

47、 of 0,000 5 N, preferably against pure potassium acid phthalate in about 100 ml of CO2-free water using phenolphthalein to detect the end point. NOTE 1 To simplify calculations, the standard KOH solution may be adjusted so that 1,00 ml is equivalent to 5,00 mg of KOH. NOTE 2 Sodium hydroxide (NaOH)

48、may be substituted for KOH. 4.3.3 p-Naphtholbenzein indicator solution Dissolve 10 g of p-naphtholbenzein per litre of titration solvent as defined in 4.3.4. p-Naphtholbenzein shall conform with Annex A. 4.3.4 Titration solvent Add 500 ml of toluene and 5 ml of water to 495 ml of anhydrous isopropyl

49、 alcohol. 4.4 Test procedure Introduce approximately 25 g of the filling compound, weighed to the nearest 0,1 g, into a 250 ml Erlenmeyer flask. Add 100 ml of the titration solvent and 0,5 ml of the indicator solution and, without stoppering, swirl until the sample is entirely dissolved by the solvent. Titrate immediately at a temperature below 30 C. Add 0,1 N KOH solution in increments and swirl to d
