Fire hazard testing - Part 10-2: Abnormal heat - Ball pressure test

This part of IEC 60695 specifies the ball pressure test as a method for evaluating the
softening temperature and accelerated material flow under load of polymeric materials and
parts of end products in their ability to resist abnormal heat. It is applicable to the materials
used in electrotechnical equipment, subassemblies and components, and to solid electrical
insulating materials except ceramics.
NOTE The Ball Pressure test method is not appropriate for certain elastomers, foamed materials, and other
materials that tend to be soft at room temperature. Product Committees are encouraged to evaluate these
materials using other methods such as IEC 60695-10-3.
This basic safety publication is intended for use by technical committees in the preparation of
standards in accordance with the principles laid down in IEC Guide 104 and
ISO/IEC Guide 51.
One of the responsibilities of a technical committee is, wherever applicable, to make use of
basic safety publications in the preparation of its publications. The requirements, test
methods or test conditions of this basic safety publication will not apply unless specifically
referred to or included in the relevant publications.

IEC 60695-10-2:2014-02(en-fr) spécifie l'essai à la bille comme méthode d'essai permettant d'évaluer la température de ramollissement et le flux accéléré sous charge des polymères et parties de produits finis, afin de vérifier leur aptitude à résister à un échauffement anormal. Elle est applicable aux matériaux utilisés dans les matériels, sous-ensembles et composants électrotechniques, et aux matériaux isolants électriques solides à l'exception des céramiques. L'essai à la bille n'est pas approprié à certains élastomères, matériaux alvéolaires et autres matériaux qui présentent une tendance au ramollissement à la température ambiante. Les comités de produits sont encouragés à évaluer ces matériaux en appliquant d'autres méthodes, telles que celles de l'IEC 60695-10-3. Cette troisième édition annule et remplace la deuxième édition de l'IEC 60695-10-2 publiée en 2003. Elle constitue une révision technique. Les principales modifications apportées par rapport à l'édition précédente sont énumérées ci-dessous:  - Ajout d'une introduction qui renseigne l'utilisateur sur les documents directeurs de base publiés par le CE 89,  - Ajout d'une référence au Guide IEC 104 et au Guide ISO/IEC 51 dans le Domaine d'application,  - Ajout d'un nouvel Article 3 comportant des termes et définitions pertinents,  - 5.2: Exigences supplémentaires applicables au support d'éprouvette d'essai sur proposition du IECEE-CTL, afin d'améliorer la reproductibilité,  - 5.3: Clarification des exigences applicables à l'étuve sur proposition du IECEE-CTL, afin d'améliorer la reproductibilité,  - 5.4: Spécification d'une résolution minimale cohérente avec les exigences relatives aux méthodes utilisant un instrument de mesure optique,  - Nouveau mode opératoire d'essai aux Articles 6 et 8, qui présente des méthodes distinctes pour les essais de validité de produit fini (Méthode A) et les essais de performance des matériaux (Méthode B), et  - Mise à jour de l'Article 11 Rapport d'essai pour alignement avec les autres documents de l'IEC 60695.  Cette norme a le statut d'une publication fondamentale de sécurité, conformément au Guide IEC 104 et au Guide ISO/IEC 51.

FIRE HAZARD TESTING –

Part 10-2: Abnormal heat – Ball pressure test method

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 60695-10-2 has been prepared by IEC technical committee 89:
Fire hazard testing.
This third edition cancels and replaces the second edition of IEC 60695-10-2 published in
2003. It constitutes a technical revision.
It has the status of a basic safety publication in accordance with IEC Guide 104 and
ISO/IEC Guide 51.

INTRODUCTION
In the design of any electrotechnical product, the risk of abnormal heat and the potential
hazards associated with abnormal heat need to be considered. In this respect the objective of
component, circuit, and product design, as well as the choice of materials, is to reduce to
acceptable levels the potential risks during normal operating conditions, reasonable
foreseeable abnormal use, malfunction and/or failure. IEC/TC 89 has developed IEC 60695-1-
10, together with its companion, IEC 60695-1-11, to provide guidance on how this is to be
accomplished.
The primary aims of IEC 60695-1-10 and IEC 60695-1-11 are to provide guidance on how:
a) to prevent ignition caused by an electrically energized component part, and
b) to confine any resulting fire within the bounds of the enclosure of the electrotechnical
product in the event of ignition.
Secondary aims of IEC 60695-1-10 and IEC 60695-1-11 include the minimization of any flame
spread beyond the product’s enclosure and the minimization of the harmful effects of fire
effluents such as heat, smoke, toxicity and/or corrosivity.
Fires involving electrotechnical products can also be initiated from external non-electrical
sources.
