NON-CELLULOSIC PAPERS FOR ELECTRICAL PURPOSES –

Part 1: Definitions and general requirements

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 60819-1 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 minor revision and technical updating.
The main changes from the previous edition are as follows: the list of materials to be used in
combination was updated with the addition of new materials made available by progress in
technology and described in Subclauses 2.7 and 2.8.

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all the parts in the IEC 60819 series, under the general title Non-cellulosic papers for
electrical purposes, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site 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.

INTRODUCTION
This International Standard forms an element of a series which deals with non-cellulosic
papers for electrical purposes.
The series consists of three parts:
Part 1: Definitions and general requirements (IEC 60819-1)
Part 2: Methods of test (IEC 60819-2)
Part 3: Specifications for individual materials (IEC 60819-3)

NON-CELLULOSIC PAPERS FOR ELECTRICAL PURPOSES –

Part 1: Definitions and general requirements

1 Scope
This part of IEC 60819 gives the definitions and general requirements for non-cellulosic
papers for electrical purposes.
Materials which conform to this specification meet established levels of performance.
However, the selection of a 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 Terms and definitions
For the purpose of this document, the following definitions apply:
2.1
aramid (aromatic polyamide) paper
wet-laid, non-woven paper in which the fibres are synthetic aromatic polyamide having at
least 85 % of the amide linkage attached directly to two aromatic rings. Aramid paper may
contain materials with or without the addition of suitable organic and/or inorganic filler and/or
binder materials.
2.2
polyethylene paper
wet-laid, non-woven paper made from specially prepared polyethylene (PE) fibres with or
without the addition of suitable organic and/or inorganic filler and/or binder materials
2.3
polypropylene paper
wet-laid, non-woven paper made from specially prepared polypropylene fibres (PP) with or
without the addition of suitable organic and/or inorganic filler and/or binder materials
2.4
glass paper
wet-laid, non-woven paper made from glass micro-fibres made with or without the addition of
suitable organic and/or inorganic filler and/or binder materials. In cases of poor fibre
adhesion, the situation may be remedied by acid treatment to produce a slight gelation which
will act as a binder, or by adding an inorganic binder.
2.5
ceramic paper
wet-laid, non-woven paper made from ceramic fibres. For examples, alumina-silica paper
composed of approximately 51 % alumina (Al O ) and 47 % silica (SiO ). Ceramic papers
2 3 2
may be modified with or without the addition of suitable organic and/or inorganic filler and/or
binder materials.
– 6 – 60819-1 © IEC:2009
2.6
poly(ethylene)-terephthalate paper
dry-laid fibre mat paper made from specially prepared polyethylene-terephthalate (PET) fibres
with or without the addition of suitable organic and/or inorganic filler and/or binder materials
NOTE Polyethylene-terephthalate paper is sometimes erroneously called PETP paper.
2.7
filled glass paper
paper in which at least 65 % of the raw material composition is glass fibres and inorganic
fillers (such as silicate of aluminium) with or without the addition of other fibres and/or binder
material
2.8
hybrid inorganic-organic paper
wet-laid, non-woven paper made from organic polymer fibres, such as Aramid or PET fibres
and inorganic fillers, such as silicates of alumina with or without addition of other fibres
and/or binder materials
3 General requirements
3.1 All materials in any one consignment shall be consistent and have properties within the
limits of this standard throughout the whole sheet or throughout the whole length of each roll.
The surface shall be uniform, reasonably smooth and reasonably free from defects such as
bubbles, pin holes, creases and flaws.
3.2 When delivered in rolls, it shall be capable of being unrolled without damage.
3.3 The combined materials shall be free of conducting particles and other undesirable
inclusions.
3.4 Materials delivered in sheets cut to length shall be reasonably free from warp.
4 Dimensions
Thickness and thickness tolerances are dealt with in the Sheets of the IEC 60819-3 series.
Other dimensions and tolerances shall be agreed by the purchaser and the supplier.
5 Joins
For material in roll form, the allowable frequency of joins, the details of their construction, and
identification shall be agreed by the purchaser and the supplier.
6 Conditions of supply
Material in roll form shall be supplied on cardboard roll or other suitable core. The inner
diameter of the core shall be agreed by purchaser and supplier, and it should preferably b
