21、est for the assessment of carbon black dispersion in polyethylene and polypropylene FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to p

22、romote 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 Reports, Publicly Available Specifications (PAS) and Guid

23、es (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 non-governmental organizations liaising with the IEC a

24、lso 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 of IEC on technical matters express, as nearly as pos

25、sible, 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 accepted by IEC National Committees in that sense. W

26、hile 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 international uniformity, IEC National Committees undertak

27、e 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 the latter. 5) IEC itself does not provide any attesta

28、tion 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 users should ensure that they have the latest edition of

29、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 other damage of any nature whatsoever, whether direct or

30、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. Use of the referenced publications is indispensable fo

31、r 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 rights. International Standard IEC 60811-607 has bee

34、d 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 general title Electric and optical fibre cables Test

35、 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 data related to the specific publication. At this da

36、te, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60811-607 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. These test methods are intended to be referenced in s

37、tandards 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 been developed and used over many years principally

38、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 60811-607 IEC:2012 ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-META

39、LLIC MATERIALS Part 607: Physical tests Test for the assessment of carbon black dispersion in polyethylene and polypropylene 1 Scope This Part 607 of IEC 60811 specifies test methods for carbon black dispersion that are applicable specifically to PE and PP compounds, including cellular compounds and

40、 foam skin for insulation. 2 Normative references The following documents, 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 do

41、cument (including any amendments) applies. IEC 60811-100:2012, Electric and optical fibre cables Test methods for non-metallic materials Part 100: General ISO 18553:2002, Method for the assessment of the degree of pigment or carbon black dispersion in polyolefin pipes, fittings and compounds 3 Terms

42、 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. The assessment shall be carried out in accordance with ISO 18553. The method is suitable for u

43、se with granules of polyethylene or granule of polypropylene compound or extrusion of polyethylene or polypropylene (for example a sheath). NOTE The method applies with less than 3 % carbon black content. ISO 18553 gives two procedures for the preparation of test specimens. Either may be used, but t

44、he following recommendations apply: the compression procedure is primarily intended for use with polyethylene compounds, but may be used for extrusions; the microtome procedure is intended for use with polyethylene extrusions. 4.2 Procedure Prepare the specified number of test specimens in accordanc

45、e with ISO 18553. 60811-607 IEC:2012 7 Using the microscopic examination technique given in ISO 18553, examine the test specimens for a) degree of dispersion. b) rating of appearance. 4.3 Expression of results Express the results of the examination in the manner given in ISO 18553. 4.4 Requirements

46、Unless otherwise stated in the relevant cable standard, the limits recommended in Annex D of ISO 18553:2002 shall be taken to indicate an acceptable degree of dispersion. NOTE Annex D of ISO 18553:2002 states: “The following limits are recommended: Grading: mean (see 5.1) 3. Appearance rating: not w

47、orse than micrograph B in Annex B (i.e. only dispersion ratings comparable to photomicrographs A1, A2, A3 and B are acceptable).” 5 Test report The test report shall be in accordance with that given in IEC 60811-100. 8 60811-607 IEC:2012 Bibliography IEC 60811-4-1:2004, Insulating and sheathing mate
