24、FROM CABLES Part 1: Determination of the halogen acid gas content 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 promote internation
25、al 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 (hereafter refe
26、rred 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 also participate in
27、 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 possible, an internat
28、ional 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. While all reasonabl
29、e 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 to apply IEC Pub
30、lications 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 attestation of conformity
31、 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 this publication.
32、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 indirect, or for c
33、osts (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 the correct appl
34、ication 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 60754-1 has been prepared by IEC te
35、chnical committee 20: Electric cables. It has the status of a group safety publication in accordance with IEC Guide 104. This third edition cancels and replaces the second edition, published in 1994, and constitutes a technical revision. The significant technical changes with respect to the previous
36、 edition are as follows: improved definition of safety requirements relating to capture of gases and use of reagents; introduction of guidance on preparation of test specimens for a more even combustion; improvements to the procedure for establishing the heating regime; improved expression of tolera
37、nces and precision; 60754-1 IEC:2011 5 definition of the procedure for the blank test; introduction of an informative annex giving details of a methodology for the determination of the halogen acid gas content of a sample representative of a cable construction. The text of this standard is based on
38、the following documents: FDIS Report on voting 20/1266/FDIS 20/1276/RVD Full information on the voting for the approval of this standard 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. A list of a
39、ll the parts in the IEC 60754 series, published under the general title Test on gases evolved during combustion of materials from cables, 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 I
40、EC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 60754-1 IEC:2011 INTRODUCTION IEC 60754 consists of the following parts, under the general title Test
41、on gases evolved during combustion of materials from cables: Part 1: Determination of the halogen acid gas content Part 2: Determination of acidity (by pH measurement) and conductivity IEC 60754-1 was developed due to concerns expressed by cable users over the amount of acid gas which is evolved whe
42、n some cable insulating, sheathing and other materials are burned, as this acid can cause extensive damage to electrical and electronic equipment not involved in the fire itself. This standard provides a method for determining the amount of acid gases evolved by burning cable components so that limi
43、ts can be agreed for cable specifications. As the test is not carried out on a complete cable test piece, for a hazard assessment the actual material volumes of the cable components should be taken into consideration. 60754-1 IEC:2011 7 TEST ON GASES EVOLVED DURING COMBUSTION OF MATERIALS FROM CABLE
44、S Part 1: Determination of the halogen acid gas content 1 Scope This part of IEC 60754 specifies the apparatus and procedure for the determination of the amount of halogen acid gas, other than hydrofluoric acid, evolved during the combustion of compounds based on halogenated polymers and compounds c
45、ontaining halogenated additives taken from electric or optical fibre cable constructions. NOTE 1 This test method is not able to determine hydrofluoric acid. A suitable method may be found in IEC 60684-2. NOTE 2 This test method may be used to test materials to be used in cable manufacture, but a de
46、claration of cable performance should not be made based on such a test. NOTE 3 The relevant cable standard should indicate which components of the cable should be tested. NOTE 4 For the purposes of this standard, the term “electric cable” covers all insulated metallic conductor cables used for the c
47、onveyance of energy or signals. The method specified in this standard is intended for the testing of individual components used in a cable construction. The use of this method will enable the verification of requirements which are stated in the appropriate cable specification for individual componen
48、ts of a cable construction. NOTE 5 By agreement between the producer and purchaser, the methodology given in this standard may be used to test combinations of materials representing a cable construction, but a declaration of cable performance to this standard should not be made based on such a test.
49、 Information on such a method is given in Annex A. For reasons of precision this method is not recommended for reporting values of halogen acid evolved less than 5 mg/g of the sample taken. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the lat
