16、ICAL COMMISSION _ INSULATING MATERIALS INDUSTRIAL RIGID ROUND LAMINATED TUBES AND RODS BASED ON THERMOSETTING RESINS FOR ELECTRICAL PURPOSES Part 3: Specifications for individual materials Sheet 3: Round laminated moulded rods FOREWORD 1) The International Electrotechnical Commission (IEC) is a worl
17、dwide 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 end and in addition to other a
18、ctivities, 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 Committee interested in the subj
19、ect 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 accordance with conditions de
20、termined 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 interested IEC National Com
21、mittees. 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 responsible for the way in whi
22、ch 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 divergence between any IEC Publica
23、tion and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure th
24、at they have the latest edition of 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 na
25、ture 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 Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenc
26、ed 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 Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. Internati
27、onal Standard IEC 61212-3-3 has been prepared by IEC technical committee 15: Standards on specifications for electrical insulating materials. This second edition cancels and replaces the first edition published in 1995 and constitutes a technical revision. The main changes from the previous edition
28、are as follows: added application use and safety statements. Reformatted document to bring it up to current IEC document format. Type EP GC 43 has been added.

34、 1 Scope This part of IEC 61212-3 gives requirements for industrial rigid round laminated moulded rods for electrical purposes, based on different resins and different reinforcements. Applications and distinguishing properties are given in Table 1. Materials which conform to this specification meet
35、established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. Safety Warning: It is the responsibility of the us
36、er 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 referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, t
37、he latest edition of the referenced document (including any amendments) applies.

41、andard 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 abbreviation, denoting the reinforc
42、ement; a serial number of two digits, the first digit denoting the form of the material, a “4” indicates moulded rods, and, a second digit denoting sub-grades of the same type. The abbreviations are given in 4.3. The complete designation of the moulded rod is denoted by: description: Moulded rod; nu
43、mber of the IEC standard: IEC 6121233; designation of the individual type; dimensions (in millimetres of the moulded rod: diameter x length) a letter designating the finish on the external diameter of the moulded rod: “A“ designating rods in the “as produced“ condition; “B“ designating rods in groun
