49 METHOD FOR THE DETERMINATION OF THE PROOF
50 AND THE COMPARATIVE TRACKING INDICES
51 OF SOLID INSULATING MATERIALS
53 FOREWORD
54 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
55 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
56 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
57 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
58 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
59 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
60 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
61 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
62 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
63 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
64 consensus of opinion on the relevant subjects since each technical committee has representation from all
65 interested IEC National Committees.
66 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
67 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
68 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
69 misinterpretation by any end user.
70 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
71 transparently to the maximum extent possible in their national and regional publications. Any divergence between
72 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
73 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
74 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
75 services carried out by independent certification bodies.
76 6) All users should ensure that they have the latest edition of this publication.
77 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
78 members of its technical committees and IEC National Committees for any personal injury, property damage or
79 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
80 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
81 Publications.
82 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
83 indispensable for the correct application of this publication.
84 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
85 rights. IEC shall not be held responsible for identifying any or all such patent rights.
86 International Standard IEC 60112 has been prepared by IEC technical committee 112:
87 Evaluation and qualification of electrical insulating materials and systems.
88 This sixth edition cancels and replaces the fifth edition published in 2020 and its Amendment
89 1:2009. This edition constitutes a technical revision.
91 This edition includes the following significant technical changes with respect to the previous
92 edition:
93 • In Clause 7.3 resistivity has been replaced by conductivity
94 It has the status of a basic safety publication in accordance with IEC Guide 104.
95 The text of this International Standard is based on the following documents:
FDIS Report on voting

98 Full information on the voting for the approval of this International Standard can be found in the
99 report on voting indicated in the above table.
100 This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
101 The committee has decided that the contents of this document will remain unchanged until the
102 stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
103 the specific document. At this date, the document will be
104 • reconfirmed,
105 • withdrawn,
106 • replaced by a revised edition, or
107 • amended.

138 METHOD FOR THE DETERMINATION OF THE PROOF
139 AND THE COMPARATIVE TRACKING INDICES
140 OF SOLID INSULATING MATERIALS
144 1 Scope
145 This document specifies the method of test for the determination of the proof and comparative
146 tracking indices of solid insulating materials on pieces taken from parts of equipment and on
147 plaques of material using alternating voltage.
148 The document provides a procedure for the determination of erosion when required.
149 NOTE 1 The proof tracking index is used as an acceptance criterion as well as a means for the quality control of
150 materials and fabricated parts. The comparative tracking index is mainly used for the basic characterization and
151 comparison of the properties of materials.
152 This test method evaluates the composition of the material as well as the surface of the material
153 being evaluated. Both the composition and surface condition directly influence the results of
154 the evaluatio
