22、al Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (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 e
23、nd and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Com
24、mittee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in a
25、ccordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements 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
26、 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. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held re
27、sponsible 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 to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any diverg
28、ence 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 attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC ma
29、rks 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 this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual exper
30、ts 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 indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Pu
31、blication 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 the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Pu

International Standard IEC 60811-606 has been prepared by IEC technical committee 20: Electric cables. This Part 606 of IEC 60811 cancels and replaces Clause 8 of IEC 60811
33、-1-3:1993, 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 previous edition, but see the Foreword to IEC 60811-100:2012. 4 60811-606 IEC:2012 The text of this standard is based on the followi

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. This part of IEC 60811
35、 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 methods for non-metallic materials, can be found on the IEC website. The committee has decided that the contents of this publica

At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60811-606 IEC:2012 5 INTRODUCTION
37、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 standards for cable construction and for cable materials. NOTE 1 Non-metallic materials are typically used for insulating, sheathi
38、ng, 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 for the materials in all energy cables. They have also been widely accepted and used for other cables, in particular optical fibr
39、e cables, communication and control cables and cables for ships and offshore applications. 6 60811-606 IEC:2012 ELECTRIC AND OPTICAL FIBRE CABLES TEST METHODS FOR NON-METALLIC MATERIALS Part 606: Physical tests Methods for determining the density 1 Scope This Part 606 of IEC 60811 descries the metho
40、ds for determining the density for the most common types of insulating and sheathing compounds (cross-linked, PVC, PE, PP, etc.). 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 refe
41、rences, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60811-100:2012, Electric and optical fibre cables Test methods for non-metallic materials Part 100: General 3 Terms and definitions For the purposes o
42、f 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. Unless otherwise specified, tests shall be carried out at room temperature. 4.2 Suspension method (general method) 4.2.1 Testing
43、materials and equipment These shall comprise: a) ethanol (ethyl-alcohol) of analytical grade or another suitable liquid for densities below 1 g/ml; b) zinc chloride solution for densities equal to or greater than 1 g/ml; c) distilled or deionized water; d) mixing cylinder; e) thermostat; f) hydromet
44、er calibrated at (23,0 0,1) C; g) thermometer graduated in tenths of a degree Celsius. 60811-606 IEC:2012 7 4.2.2 Procedure From the insulation or the sheath to be tested, a sample shall be taken perpendicularly to the conductor axis and cut into small pieces of 1 mm to 2 mm edge length. The density
45、 shall be determined by putting the sample in suspension in a liquid which does not react with the material to be tested. The following liquids are suitable: for a density expected to be lower than 1 g/ml, a mixture of ethanol and water; for a density of 1 g/ml and higher, a mixture of zinc chloride
46、 and water. Three pieces of the sample shall be placed in the liquid at a temperature of (23,0 0,5) C, avoiding any formation of air bubbles. Distilled water shall be added to the liquid until the pieces are freely suspended within the liquid in the mixing cylinder. The liquid mixture shall be homog
47、eneous and maintained at the indicated temperature. The density of the liquid mixture shall be determined by means of the hydrometer and indicated to three decimal places; the determined density is the same as that of the samples under test. NOTE The gradient method specified in ISO 1183 may also be
48、 used. 4.3 Pycnometer method (reference method) 4.3.1 Testing equipment The testing equipment for this method consists of a balance with a precision of 0,1 mg, a pycnometer of 50 ml capacity, a liquid bath provided with a thermostatic control, immersion liquid (ethyl alcohol, 96 %). 4.3.2 Sample and
49、 test piece preparation The test piece shall be taken from the bare insulation or sheath. The mass of the test piece shall be not less than 1 g and not greater than 5 g. The test piece shall be made by cutting the sample of insulation or sheath into a number of small pieces; small tubes of insulation and sheath shall be cut longitudinally into two or more parts to prevent the enclosure
