24、lectrotechnical 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 fiel
25、ds. To this end 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
26、 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 this preparation. IEC collaborates closely with the International Organization for Standardizat
27、ion (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 international consensus of opinion on the relevant subjects since each technical committee has represent
28、ation 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 reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC can
29、not 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 Publications transparently to the maximum extent possible in their national and regional publicatio
30、ns. 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. Independent certification bodies provide conformity assessment services and, in some areas, ac
31、cess 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. 7) No liability shall attach to IEC or its directors, employees, servants or agents including in
32、dividual 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 costs (including legal fees) and expenses arising out of the publication, use of, or reliance upo
33、n, 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 application of this publication. 9) Attention is drawn to the possibility that some of the elements
34、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 61212-3-2 has been prepared by IEC technical committee 15: Solid electrical insulating material. This third edition cancels and rep
35、laces the second edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: Details of test for insulation resistance after immersion in water are changed. 4 61212-3-2 IEC:2013 The
36、text of this standard is based on the following documents: FDIS Report on voting 15/700/FDIS 15/710/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
37、 Directives, Part 2. A list of all parts in the IEC 61212 series, published under the general title Insulating materials Industrial rigid round laminated tubes and rods based on thermosetting resins for electrical purposes, can be found on the IEC website. The committee has decided that the contents
38、 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, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61212-3-2 IEC:2013
39、 5 INTRODUCTION This part of IEC 61212 is one of a series which deals with industrial rigid round laminated tubes and rods based on thermosetting resins for electrical purposes. This series consists of three parts: Part 1: Definitions, designations and general requirements (IEC 61212-1) Part 2: Meth
40、ods of test (IEC 61212-2) Part 3: Specifications for individual materials (IEC 61212-3) IEC 61212-3-2 contains one of the specification sheets comprising Part 3, as follows: Sheet 2: Round laminated moulded tubes. 6 61212-3-2 IEC:2013 INSULATING MATERIALS INDUSTRIAL RIGID ROUND LAMINATED TUBES AND R
41、ODS BASED ON THERMOSETTING RESINS FOR ELECTRICAL PURPOSES Part 3: Specifications for individual materials Sheet 2: Round laminated moulded tubes 1 Scope This part of IEC 61212 gives requirements for industrial rigid round laminated moulded tubes for electrical purposes, based on different resins and
42、 different reinforcements. Applications and distinguishing properties are given in Table 1. Materials which conform to this specification meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements neces
43、sary for adequate performance in that application and not based on this specification alone. Safety Warning: It is the responsibility of the user of the methods contained or referred to in this document to ensure that they are used in a safe manner. 2 Normative references The following documents, in
44、 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 61212-1, Insulating materials

46、s Part 2: Methods of test 3 Terms and definitions For the purposes of this document, the following term and definition apply. 3.1 moulded tube tube formed by rolling impregnated layers of material on a mandrel, curing the assembly in a cylindrical mould under heat and pressure, and then removing the
47、 mandrel SOURCE: ISO 472:1999, modified In the ISO definition, the term “laminated moulded tube” is used instead of “moulded tube” and an indication “or other suitable” is provided between the words “cylindrical” and “mould”. 61212-3-2 IEC:2013 7 4 Designations and abbreviations 4.1 General The moul
48、ded tubes covered by this Part 3 sheet are classified into types which differ in the resin and reinforcement used, the method of manufacture and their distinguishing properties. 4.2 Designation Individual types are designated by: a two-letter abbreviation denoting the resin; a second two-letter abbr
49、eviation, denoting the reinforcement; a serial number of two digits, the first digit denoting the form of the material, a “3” indicates moulded tubes, and, a second digit denoting sub-grades of the same type. The abbreviations are given in 4.3. The complete designation of the moulded tube is denoted by: description: moulded tube; number of the IEC standard: I
