IEC 60695-10-2:2014

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

IEC 60695-10-2:2014 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. 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 third edition cancels and replaces the second edition of IEC 60695-10-2 published in 2003. It constitutes a technical revision. The main changes with respect to the previous edition are as follows:
- The addition of an introduction introduces the user to the basic guidance documents published by TC 89,
- Addition of a reference to IEC Guide 104 and ISO/IEC Guide 51 in the Scope,
- Additional relevant Terms and Definitions in new Clause 3,
- 5.2: Additional requirements to the test specimen support at the suggestion of IECEE-CTL to improve reproducibility,
- 5.3: Clarification of heating oven requirements at the suggestion of IECEE-CTL to improve reproducibility,
- 5.4: Specification of minimum resolution consistent with method requirements for optical measurement instrument,
- New Test Procedure in Clauses 6 and 8 which introduces separate methods for End Product proof testing (Method A) and material performance testing (Method B) and
- Updated Clause 11 Test Report to be consistent with other IEC 60695 documents.
Key words: Abnormal heat, Ball pressure test method, Fire hazard

Essais relatifs aux risques du feu - Partie 10-2: Chaleurs anormales - Essai à la bille

IEC 60695-10-2:2014 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.

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.
