23、l materials Requirements for rigid laminated sheets based on phenolic resins 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
24、international 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 (her
25、eafter referred 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 par
26、ticipate in 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,
27、an international 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 al
28、l reasonable 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 ap
29、ply IEC Publications 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
30、 conformity. 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 pu
31、blication. 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 indirec
32、t, 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 referenced publications is indispensable for the c
33、orrect 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. This consolidated version of IEC 60893-3-4 consists
34、 of the second edition (2003) documents 15C/1524/FDIS and 15C/1538/RVD and its amendment 1 (2012) documents 15/682/FDIS and 15/688/RVD. It bears the edition number 2.1. The technical content is therefore identical to the base edition and its amendment and has been prepared for user convenience. A ve
35、rtical line in the margin shows where the base publication has been modified by amendment 1. Additions and deletions are displayed in red, with deletions being struck through. 4 60893-3-4 IEC:2003+A1:2012 International Standard IEC 60893-3-4 has been prepared by subcommittee 15C: Specifications, of
36、IEC technical committee 15: Insulating materials. In this revision of the IEC 60893 series of specifications, new material types have been included, changes have been made to the property requirements of some existing types, a new method for testing permittivity and dissipation factor has been added
37、, and all non-specification data for each type has been moved to a new Part 4 document IEC 60893-4 Typical values. The amendment introduces revised limits for CHARPY and IZOD impact strengths for the requirements of all types of rigid laminated sheets based on phenolic resins. These revised limits a
38、re based on the results of round-robin testing. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of the base publication and its amendments will remain unchanged until the stability date indicated on the IEC web site und
39、er “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. IMPORTANT The “colour inside” logo on the cover page of this publication indicates that it contains colours which are c
40、onsidered to be useful for the correct understanding of its contents. Users should therefore print this publication using a colour printer. 60893-3-4 IEC:2003+A1:2012 5 INTRODUCTION This part of IEC 60893 is one of a series, which deals with industrial rigid laminated sheets based on thermosetting r
41、esins for electrical purposes. This series consists of four parts: Part 1: Definitions, designations and general requirements (IEC 60893-1) Part 2: Methods of test (IEC 60893-2) Part 3: Specifications for individual materials (IEC 60893-3) Part 4: Typical values (IEC 60893-4) IEC 60893-3-4 contains
42、one of the specification sheets comprising Part 3, as follows: Sheet 4: Requirements for rigid laminated sheets based on phenolic resins 6 60893-3-4 IEC:2003+A1:2012 INSULATING MATERIALS INDUSTRIAL RIGID LAMINATED SHEETS BASED ON THERMOSETTING RESINS FOR ELECTRICAL PURPOSES Part 3-4: Specifications
43、for individual materials Requirements for rigid laminated sheets based on phenolic resins 1 Scope This part of IEC 60893 gives the requirements for industrial rigid laminated sheets for electrical purposes based on phenolic resin and different reinforcements. Applications and distinguishing properti
44、es 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 necessary for adequate performance in that application and not based on
45、this specification alone. 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 any amendments) applies.
