COMBINED FLEXIBLE MATERIALS
FOR ELECTRICAL INSULATION –
Part 3: Specifications for individual materials
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
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 (hereafter 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 participate 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, 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 all 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 apply 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in 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 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 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 responsible for identifying any or all such patent rights.
International Standard IEC 60626-3 has been prepared by IEC technical committee 15: Solid
electrical insulating materials.
This third edition cancels and replaces the second edition published in 1996 and its
amendment 1 (1999), and constitutes a technical revision. The main changes from the previous
edition are as follows:
– consolidation of amendment 1 published in 1999 which was mainly describing the sheets
from 340 to 459;
– revision and reordering of previous tables of 1996 edition.

COMBINED FLEXIBLE MATERIALS
FOR ELECTRICAL INSULATION –
Part 3: Specifications for individual materials
1 Scope
This part of IEC 60626 specifies dimensional and performance requirements for individual
combined flexible materials for electrical insulation. This part is in the form of groups of sheets.
Sheets are numbered in accordance with Table 1, which provides a complete list of all the
specification sheets belonging to this standard.
Materials which conform to this specification meet established levels of performance. However,
the selection of 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 document 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 any amendments) applies.
The list of normative references is extensive because, in order to obtain a combination of two
or more materials for electrical insulation, it is necessary that those base materials (paper, film,
etc.) shall conform to the requirements set forth, in the appropriate specification of the base
material alone, for that purpose. This rule shall be applied also in the development of new
possible combinations; to this end, specifications of materials not actually used, but
referenced, may be eligible for future developments.

3 Requirements
In addition to complying with the general requirements of IEC 60626-1, each flexible combined
laminate shall conform to the requirements set forth in the appropriate sheet corresponding to
its type, as shown in the sheets of this standard.
4 Designation
Table 1 lists material designations and constructions appropriate to each sheet. Material
conforming to this specification shall be identified by a designation containing the IEC standard
number, the material designation from IEC 60626-1 and the nominal thickness. For example:
IEC 60626-3, Sheet 112, P-C/F-PET/P-C, 0,15 mm
5 Thermal classification
Performance experience provides information about the thermal capability of combined flexible
materials in electrical insulation systems. This information is given in each individual sheet.
Thermal classification information on these sheets is not to be considered as a requirement.
6 Specification sheets
The presently 31 sheets listed in the Introduction are organised according to the composition of
the laminates as described in the following master listing Table 1, including sections that could
be offered by the market in the future; therefore classification numbering is already provided
for future growth.

Sheet 100
Requirements for combined flexible duplex materials of two layers –
F-PET/P-C (23 μm PET film with presspaper or paper)
1 Description
This sheet gives the requirements for duplex materials consisting of paper or presspaper
containing sulphate wood pulp fibres (P-C) laminated on a polyethylene terephthalate film
(F-PET) having a nominal thickness of 23 μm.
2 Thermal classification
Experience has shown that the combined flexible materials listed in this sheet may be suitable
for use in electrical apparatus with ratings up to and including the range of 120 °C to 130 °C.
3 Single-layer requirements
Use paper which meets the requirements for classes 1.1, 1.2, 1.3 or 1.4 of IEC 60554-1 and
IEC 60554-3. Alternatively, use presspaper which meets the requirements for P2, P4 or P6 of
IEC 60641-1 and IEC 60641-3-2. Each of these presspapers or papers can have a different
density, which will affect the nominal grammage of the laminate.
Use a PET film, which has a nominal thickness of 23 μm and meets the requirements of
IEC 60674-1 and IEC 60674-3-2.
4 Breakdown voltage requirements
For all laminates listed in Clause 5, the minimum electric breakdown voltage using 6 mm
diameter electrodes is
– for unfolded specimens: 6 kV;
– for folded specimens: 5 kV.
However, in accordance with IEC 60626-2, a minimum electric breakdown voltage on folded
specimens is not required for laminates of nominal thickness greater than 0,5 mm.
