Sestavljeni gibki materiali za električno izolacijo - 2. del: Preskusne metode (IEC 60626-2:2009)
Ta mednarodni standard zagotavlja preskusne metode za sestavljene gibke materiale za električno izolacijo. Potrjene so bile nekatere lastnosti in ustrezne preskusne metode v skladu z zahtevami za zmogljivosti IEC 60626-3. Druge preskusne metode so opisane kot dodatek vodilu za nadaljnjo specifikacijo, o kateri se lahko dogovorita stranka in dobavitelj, da ustreza posebnim potrebam za končno uporabo. Materiali, skladni s to specifikacijo, ustrezajo vzpostavljenim ravnem delovanja. Vendar mora uporabnik material za določeno uporabo izbrati na podlagi dejanskih zahtev za ustrezno delovanje pri takšni uporabi in ne le na podlagi same specifikacije. VARNOSTNO OPOZORILO: Uporabnik je odgovoren, da se metode, ki so opisane v tem dokumentu ali na katere se dokument sklicuje, uporabljajo na varen način.

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 60626-2 has been prepared by IEC technical committee 15: Solid
electrical insulating materials.
This third edition cancels and replaces the second edition published in 1995 and constitutes a
major technical revision. The main changes from the previous edition are as follows: some
tests such as for edge tearing and stiffness, actually not used and not listed in the
requirements of Part 3, were deleted.

INTRODUCTION
This International standard deals with test methods of combined flexible materials consisting
of two or more different insulating materials laminated together as described in IEC 60626-1.
The components of flexible combined materials are polymer film and fibrous sheet material.
This standard does not include materials based on mica paper, as primary component,
covered by IEC 60371, but mica paper may be used as complementary material.
The series has three parts describing:
Part 1: Definitions and general requirements (IEC 60626-1)
Part 2: Methods of test (IEC 60626-2)
Part 3: Specifications for individual materials (IEC 60626-3)

COMBINED FLEXIBLE MATERIALS
FOR ELECTRICAL INSULATION –
Part 2: Methods of test
1 Scope
This International Standard provides the test methods for combined flexible materials for
electrical insulation. Some properties and relevant test methods, according to the perfomance
requirements of IEC 60626-3, were confirmed. Other test methods are described as a
supplement of guidance for further specification that could be agreed between customer and
supplier to meet specific needs of the end use.
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.

3 General requirements on tests
Unless otherwise specified, the test specimens, after being cut, shall be conditioned for 24 h
at (23 ± 2) °C and (50 ± 5) % relative humidity. If the test is not conducted in this standard
atmosphere, the test shall be made within 5 min after removal from the standard atmosphere.

4.1 Test apparatus
4.1.1 An external screw type micrometer having measuring faces of 6 mm to 8 mm diameter.
The measuring faces shall be flat to within 0,001 mm and parallel to within 0,003 mm. The
pitch of the screw shall be 0,5 mm and the graduations shall be 50 divisions of 0,01 mm,
enabling readings to be estimated to 0,002 mm.
The pressure exerted on the specimens shall be 100 kPa as described in 4.1.2.
4.1.2 A dead-weight dial type micrometer having two ground and lapped concentric circular
surfaces flat to within 0,001 mm and parallel to within 0,003 mm. The upper surface shall be 6
mm to 8 mm in diameter. The lower surface shall be larger than the upper one. The upper
surface shall move on the axis perpendicular to the surfaces. The dial shall be graduated to
read directly to 0,002 mm. The frame of the micrometer shall be of such rigidity that a force of
15 N applied to dial housing, out of contact with either the weight or the presser foot spindle,
will produce a deflection of the frame not greater than 0,002 mm as indicated on the
micrometer dial. The pressure exerted on the specimen shall be 100 kPa.
4.1.3 The setting gauge used to check the instruments shall be accurate to within
±0,001 mm of the nominal size. The indicated thickness by t
