IEC 60819-3-3:2011

Non-cellulosic papers for electrical purposes - Part 3: Specifications for individual materials - Sheet 3: Unfilled aramid (aromatic polyamide) papers

IEC 60819-3-3:2011 is a sheet of IEC 60819-3 specifies requirements for four types of unfilled aramid papers:
- Type 1: calendered paper;
- Type 2: calendered paper, with improved tearing resistance and conformability;
- Type 3: uncalendered paper;
- Type 4: calendered paper, with lower density for laminating.
This edition includes the following significant technical changes with respect to the previous edition:
- normative references change: all the requirements are now determined according the clauses of test methods from IEC 60819-2 specific for non cellulosic papers, instead of IEC 60554-2:2001 generally valid for cellulosic papers;
- and some new, very thin thicknesses, of type 4, calendered paper with lower density for laminating, were added.

Papiers non cellulosiques pour usages électriques - Partie 3: Spécifications pour matériaux particuliers - Feuille 3: Papiers en aramide non chargé (polyamide aromatique)

La CEI 60819-3-3:2011 est une feuille de la CEI 60819-3 qui spécifie les exigences pour quatre types de papiers en aramide non chargé:
- Type 1: papier calandré;
- Type 2: papier calandré, avec une résistance au déchirement et une adaptabilité améliorées;
- Type 3: papier non calandré;
- Type 4: papier calandré, avec une densité plus faible de stratification.
Cette édition inclut les modifications techniques significatives suivantes par rapport à l'édition précédente:
- modification des références normatives: toutes les exigences sont à présent déterminées conformément aux articles des méthodes d'essai figurant dans la CEI 60819-2 spécifique aux papiers non cellulosiques, au lieu de la CEI 60554-2:2001 généralement valable pour les papiers cellulosiques;
- certains nouveaux papiers calandrés, d'épaisseurs très minces, de type 4, avec une densité plus faible de stratification, ont été ajoutés.

NON-CELLULOSIC PAPERS FOR ELECTRICAL PURPOSES –

Part 3: Specifications for individual materials –
Sheet 3: Unfilled aramid (aromatic polyamide) papers


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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks 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 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 60819-3-3 has been prepared by IEC technical committee15: Solid
electrical Insulating materials.
This third edition cancels and replaces the second edition published in 2006. This edition
constitutes a technical revision. This edition includes the following significant technical
changes with respect to the previous edition:
– normative references change: all the requirements are now determined according the
clauses of test methods from IEC 60819-2 specific for non cellulosic papers, instead of
IEC 60554-2:2001 generally valid for cellulosic papers;
– some new, very thin thicknesses, of type 4, calendered paper with lower density for
laminating, were added.

INTRODUCTION
This International Standard is one 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).
This standard is one of the sheets comprising Part 3:
Sheet 3: Unfilled aramid (aromatic polyamide) papers

NON-CELLULOSIC PAPERS FOR ELECTRICAL PURPOSES –

Part 3: Specifications for individual materials –
Sheet 3: Unfilled aramid (aromatic polyamide) papers



1 Scope
This sheet of IEC 60819-3 specifies requirements for four types of unfilled aramid papers:
Type 1: calendered paper;
Type 2: calendered paper, with improved tearing resistance and conformability;
Type 3: uncalendered paper;
Type 4: calendered paper, with lower density for laminating.
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.
IEC 60819-1, Non-cellulosic papers for electrical purposes – Part 1: Definitions and general
requirements
IEC 60819-2: 2001, Non-cellulosic papers for electrical purposes – Part 2: Methods of test
IS0 186:2002, Paper and board – Sampling to determine average quality
3 Requirements
Papers shall satisfy the general requirements in IEC 60819-1, and shall in addition comply
with the requirements specified in Table 1 of this part. In assessing conformity with the
requirements in Table 1, the sampling procedures used shall be in accordance with ISO 186.
In all cases, the values given in Table 1 are the central values, with the number of test pieces
to be in accordance with the reference test methods.
