27、al 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 fields. To this e
28、nd 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 National Com
29、mittee 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 Standardization (ISO) in
30、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 representation from al
31、l 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 cannot be held r
32、esponsible 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 publications. Any diver
33、gence 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, access to IEC m
34、arks 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 individual expe
35、rts 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 upon, this IEC P
36、ublication 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 of this IEC P
37、ublication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62631-3-1 has been prepared by IEC technical committee TC 112: Evaluation and qualification of electrical insulating materials and systems. This
38、 first edition of IEC 62631-3-1 cancels and replaces the second edition of IEC 60093, published in 1980. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the second edition of IEC 60093: a) IEC 60093 has been completely
39、revised, both editorially and technically, and incorporated into the new IEC 62631 series; b) test methods have been updated to current day state of the art; c) volume and surface resistance and resistivity are now separated to appear in this part of IEC 62631 and in IEC 62631-3-2, respectively. 4 I
40、EC 62631-3-1:2016 IEC 2016 The text of this standard is based on the following documents: FDIS Report on voting 112/339/FDIS 112/350/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. This publication has been draft
41、ed in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 62631 series, published under the general title Dielectric and resistive properties of solid insulating materials, can be found on the IEC website. The committee has decided that the contents of this publication wil
42、l remain unchanged until the stability date indicated on the IEC website 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. IEC 62631-3-1:2016 IEC 2016 5 DIELECTRIC AN
43、D RESISTIVE PROPERTIES OF SOLID INSULATING MATERIALS Part 3-1: Determination of resistive properties (DC methods) Volume resistance and volume resistivity General method 1 Scope This part of IEC 62631 covers a method of test for the determination of volume resistance and volume resistivity of electr
44、ical insulation materials by applying a DC voltage. 2 Normative references The following documents, in 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 edi
45、tion of the referenced document (including any amendments) applies.

47、nitions For the purposes of this document, the following terms and definitions apply. 3.1 volume resistance part of the insulation resistance which is due to conduction through the volume Note 1 to entry: Volume resistance is expressed in the unit of . 3.2 volume resistivity volume resistance of a m
48、aterial related to its volume Note 1 to entry: Volume resistivity is expressed in the unit of m. Note 2 to entry: For insulating materials, the volume resistivity is usually determined by means of measuring electrodes arranged on a sheet of the material. Note 3 to entry: According to IEC 60050-121:
49、Electromagnetism, “conductivity” is defined as “scalar or tensor quantity, the product of which by the electric field strength in a medium is equal to the electric current density” and “resistivity” as “the inverse of the conductivity when this inverse exists”. Measured in this way, the volume 6 IEC 62631-3-1:2016 IEC 2016 resistivity is an average of the resistivity over possi
