21、ectrotechnical 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 field
22、s. 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
23、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 Standardizati
24、on (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 representa
25、tion 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 cann
26、ot 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 publication
27、s. 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 in conformity with an IEC P
28、ublication. 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 for any personal injury,
29、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 Normative references cited
30、 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 responsible for identifying
31、 any or all such patent rights. International Standard IEC 60454-2 has been prepared by IEC technical committee 15: Solid electrical insulating materials. This third edition cancels and replaces the second edition published in 1994, and constitutes a technical revision. This revision includes improv
32、ed text regarding the flame test (Clause 20), the improved text on adhesion (Clause 11) and a new Figures 9a and 9b. The text of this standard is based on the following documents: FDIS Report on voting 15/377/FDIS 15/387/RVD Full information on the voting for the approval of this standard can be fou

44、preparation Unless otherwise specified, rolls are to be conditioned for at least 24 h at (23 2) C and (50 5) % relative humidity and all test procedures are to be carried out in this atmosphere. Remove and discard the three outer turns before taking any test specimens from the conditioned roll. Spec
45、imen preparation shall be done with care in a clean environment. Specific specimen preparation details will be included with the appropriate test method. Further conditioning of test specimens may be required. 4 Determination of thickness 4.1 Test apparatus A dead-weight thickness gauge having two g
46、round and concentric circular surfaces, flat within 0,001 mm and parallel to within 0,003 mm. The upper surface shall be 6 mm to 8 mm in diameter and the lower surface larger than the upper one. The upper surface shall move on the axis perpendicular to the two faces. The gauge shall be graduated to
47、read directly to 0,002 mm. The frame of the thickness gauge shall be of such rigidity that a load of 15 N applied to the gauge housing, out of contact with either the weight or the pressure foot spindle, will produce a deflection of the frame not greater than 0,002 mm (as indicated on the thickness
48、gauge). The pressure exerted on the specimen shall be (50 5) kPa. The accuracy of the thickness gauge shall be checked frequently by means of a set of steel gauges; the measuring errors of the thickness gauge shall not exceed 0,005 mm. 4.2 Test specimens Five specimens, at least 75 mm long, are cut from the roll at intervals not less than 300 mm. The specimen shall be allowed to relax for at least 5 min. 4.3 Procedure Place the test specimen between the jaws of the t
