21、us tests Measurement of mass increase of polyethylene and polypropylene compounds 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 pro

22、mote 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 Guides

23、 (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 als

24、o 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 possi

25、ble, 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. Whi

26、le 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 undertake

27、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 attestati

28、on 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 th

29、is 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 in

30、direct, 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 for

31、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 60811-407 has been

32、prepared by IEC technical committee 20: Electric cables. This Part 407 of IEC 60811 cancels and replaces Clause 11 of IEC 60811-4-2:2004, which is withdrawn. Full details of the replacements are shown in Annex A of IEC 60811-100:2012. There are no specific technical changes with respect to the previ

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 date

36、, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60811-407 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 sta

37、ndards 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 fo

38、r 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 60811-407 IEC:2012 ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALL

39、IC MATERIALS Part 407: Miscellaneous tests Measurement of mass increase of polyethylene and polypropylene compounds 1 Scope This Part 407 of IEC 60811 gives the procedure to examine possible interaction between insulation material and filling compound of filled cable. 2 Normative references The foll

40、owing 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 document (including any amendments) applies. IEC 60811-100:2

41、012, Electric 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 6

42、0811-100. This test is used to examine the possible interaction between insulation materials and filling compounds of filled cables. It is intended only for the purpose of material selection. 4.2 Apparatus For the purpose of this test, the different equipment used is as follows: a) a glass vessel; b

43、) an oven with natural air flow; c) an analytical balance with a precision of 0,1 mg. 4.3 Sampling and test pieces preparation Three samples of each colour of insulated core shall be taken from a cable before the filling process. Each sample of about 2 m shall be cut into three pieces of length 600

44、mm, 800 mm and 600 mm. 60811-407 IEC:2012 7 4.4 Test procedure The 800 mm test piece shall be immersed in about 200 g of filling compound contained in a glass vessel and pre-heated to the following temperature: (60 2) C for filling compound having a drop-point above 50 C and up to and including 70 C

45、; (70 2) C for filling compound having a drop-point above 70 C. NOTE For an explanation of the drop-point, see IEC 60811-601. At least 500 mm of the middle part of this test piece shall be immersed in the compound without contact with the glass vessel or another specimen. The ends of the test piece

46、shall be kept out of the compound. The glass vessel shall be stored for 10 24 h in an oven and the temperature shall be maintained continuously at the value specified above for the relevant filling compound. At the end of the period, the test piece shall be removed from the filling compound and care

47、fully cleaned with absorbent paper. The ends of the test piece shall then be cut away leaving at least 500 mm of the middle part that has been immersed in the filling compound. The two dry 600 mm pieces shall be cut back to the same length as the immersed test piece and the conductor shall be remove

48、d from all three. 4.5 Measurements The three test pieces shall be weighed at ambient temperature to the nearest 0,5 mg. 4.6 Expression of the result The mass increase W, expressed in per cent, shall be determined as follows: 100112=MMMW where M1is the mean mass of the two dry test pieces; M2is the m

49、ass of test piece immersed in the filling compound. 5 Test report The test report shall be in accordance with that given in IEC 60811-100. 8 60811-407 IEC:2012 Bibliography IEC 60811-4-2:2004, Insulating and sheathing materials of electric and optical cables Common test methods Part 4-2: Methods specific to polyethylene and polypropylene compounds Tensile strength and e
