19、RD 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 international co-operation on all questions concerning standardization in the elect
20、rical 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 referred to as “IEC Publication(s)”). Their preparation is entrusted to tech
21、nical 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 this preparation. IEC collaborates closely with the International Orga
22、nization 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 international consensus of opinion on the relevant subjects since each technica
23、l 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 reasonable efforts are made to ensure that the technical content of IEC Publicat
24、ions 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 Publications transparently to the maximum extent possible in their nationa
25、l 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be i
26、n conformity with an IEC Publication. 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 experts and members of its technical committees and IEC National Committees
27、 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 Publication or any other IEC Publications. 8) Attention is drawn to the
28、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 Publication may be the subject of patent rights. IEC shall not be held r
29、esponsible for identifying any or all such patent rights. International Standard IEC 61061-1 has been prepared by IEC technical committee 15: Solid electrical insulating materials. This third edition cancels and replaces the second edition published in 1998, and constitutes a technical revision. The
30、 main changes from the previous edition are as follows: addition of application use and safety statements; redefinition of ring and sheet; appropriate additions to the subclauses; reformatting of text to bring it in line with current IEC document format. 61061-1 IEC:2006 3 This bilingual version, pu
31、blished in 2009-09, corresponds to the English version. The text of this standard is based on the following documents: FDIS Report on voting 15/343/FDIS 15/350/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. The
32、French version of this standard has not been voted upon. A list of all parts of the IEC 61061 series, under the general title Non-impregnated densified laminated wood for electrical purposes, can be found on the IEC website. The committee has decided that the contents of this publication will remain
33、 unchanged until the maintenance result 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. 4 61061-1 IEC:2006 NON-IMPREGNATED DENSIF
34、IED LAMINATED WOOD FOR ELECTRICAL PURPOSES Part 1: Definitions, designation and general requirements 1 Scope This part of IEC 61061 includes the definitions required for the understanding of all three parts of the standard, the designation of the material types and the general requirements applicabl
35、e to non-impregnated densified laminated wood for electrical purposes. This specification is intended to cover only sheets and rings of nominal thicknesses between 6 mm and 100 mm, inclusive. Materials which conform to this specification meet established levels of performance. However, the selection
36、 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 user of the methods contained or referred to in this docume
37、nt 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, the latest edition of the referenced document (including a
38、ny amendments) applies. IEC 60296, Fluids for electrotechnical applications Unused mineral insulating oils for transformers and switchgear IEC 61061-2, Non-impregnated, densified laminated wood for electrical purposes Part 2: Methods of test IEC 61061-3 (all sheets), Non-impregnated, densified lamin
39、ated wood for electrical purposes Part 3: Specifications for individual materials 3 Terms and definitions For the purposes of this document, the following terms and definitions apply: 3.1 veneer single non-laminated ply with a thickness of not more than 2,5 mm in the non-pressed condition, for examp
40、le produced from beech (fagus silvatica), North-American maple (acer saccherem) or birch (betula pendula) 3.2 non-impregnated densified laminated wood laminated wood made from layers of wood veneer bonded together under controlled conditions of heat and pressure using a thermosetting synthetic resin

42、ing out the ring from a sheet made with crosswise arrangement of veneers (positioned at 90 to one another); b) pressing substantially tangentially arranged veneers laid up in a circular form; or c) pressing veneers assembled in a circular form, with each layer arranged at 45 to the layer preceding i
43、t NOTE Because of the different methods of manufacture which may be used, the three types clearly differ in their properties and therefore the required type of ring should be specified in the purchase contract. 4 Designation 4.1 General The types of material covered by this specification shall be de
44、signated by: the shape of the material: sheet or ring; the number of the IEC standard: IEC 61061; a letter to denote the arrangement of the veneers according to 4.2; a digit to denote the range of densities according to 4.3; a letter to denote the kind of wood according to 4.4; the dimensions of the
45、 sheet: thickness in millimetres width in millimetres length in millimetres; ring: thickness in millimetres radial ring width in millimetres outer diameter in millimetres. 4.2 Arrangements of veneers The arrangement of veneers shall be denoted by the following letters: P: parallel arrangement; C: cr
46、osswise arrangement; T: tangential arrangement; A: veneers arranged at 45 to the preceding layer. NOTE In arrangements P and T, for manufacturing reasons, up to 20 % of the veneers may be arranged in such a manner that the fibres are perpendicular to the fibres of the rest of the veneers. When arran
47、ging the layers crosswise, it is permissible to have two veneers on top of each other in the same direction, in order to compensate for the variation in mass of each ply of veneer. 4.3 Apparent density in grams per cubic centimetre (g/cm 3 ) The apparent density shall be denoted by the following dig
48、its: 6 61061-1 IEC:2006 1: apparent density 0,7 0,9 g/cm 3 ; 2: apparent density 0,9 1,1 g/cm 3 ; 3: apparent density 1,1 1,2 g/cm 3 ; 4: apparent density 1,2 1,3 g/cm 3 . 4.4 Kind of wood The kind of wood shall be denoted by the following letters: B: birch; M: maple; R: beech. 4.5 Examples of compl
