Fire hazard testing - Part 10-3: Abnormal heat - Mould stress relief distortion test

Specifies the mould stress relief distortion test as a test method for use by product committees. It is applicable to electrotechnical equipment including parts made from polymeric materials. This test is intended to simulate the effects caused by the relieving of moulding stresses by conditioning the product or part at a temperature higher than the maximum normal operating temperature and observing the nature of the resulting changes. Has the status of a basic safety publication in accordance with IEC Guide 104.

Essais relatifs aux risques du feu - Partie 10-3 : Chaleur anormale - Essai de déformation par réduction des contraintes de moulage

L'IEC 60695-10-3:2016 spécifie un essai de déformation par réduction des contraintes de moulage. Elle est applicable aux matériels électrotechniques, y compris les parties composées de matériaux polymères. Cette méthode d'essai est destinée à évaluer les effets provoqués par la réduction des contraintes résiduelles induites par traitement, se produisant dans un assemblage polymère moulé d'un produit final. Cette réduction de contraintes se produit lorsque l'échantillon (sous ou hors tension) est exposé au conditionnement à une température définie pendant une période de temps définie. L'éprouvette d'essai est considérée comme ayant satisfait à l'essai si, après le conditionnement à température ambiante, elle satisfait aux critères d'essai définis. La présente publication fondamentale de sécurité est essentiellement destinée à être utilisée par les comités d'études dans le cadre de l'élaboration de normes conformément aux principes établis dans le Guide IEC 104 et le Guide ISO/IEC 51. Elle n'est pas destinée à être utilisée par les fabricants ou les organismes de certification. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - Références mises à jour; - Matériel mis à jour; - Termes et définitions ajoutés; - et Bibliographie ajoutée. Mots-clés: Risques du feu, Chaleur anormale, l'ingénierie de la sécurité incendie, déformation par réduction des contraintes de moulage

Preskušanje požarne ogroženosti - 10-3. del: Nenormalna toplota - Sproščanje obremenitve po porušitvenem preskusu odlitka (IEC 60695-10-3:2016)

Določa sproščanje obremenitve po porušitvenem preskusu odlitka kot preskusno metodo, ki jo uporabljajo tehnični odbori. Uporablja se za elektrotehnično opremo, vključno z deli, ki so izdelani iz polimernih materialov. Namen tega preskusa je simulacija vplivov, ki jih povzroči sproščanje obremenitev odlitka pri obdelavi izdelka ali njegovega dela pri temperaturi, ki je višja od najvišje običajne delovne temperature, in opazovanje lastnosti sprememb, ki so posledica teh vplivov. Ta standard ima status osnovne varnostne publikacije v skladu z vodilom 104 Mednarodne elektrotehniške komisije.

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 60695-10-3 has been prepared by IEC technical committee 89:
Fire hazard testing.
The text of this standard is based on the following documents:
FDIS Report on voting

ISO/IEC Guide 51.
This second edition of IEC 60695-10-3 cancels and replaces the first edition issued in 2002. It
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Updated references;
b) Updated equipment;
c) Added terms and definitions; and
d) Added Bibliography.
A list of all the parts in the IEC 60695 series, under the general title Fire hazard testing, can
be found on the IEC website.
The IEC 60695-10 series, under the general title Fire hazard testing, consists of the following
parts:
• Part 10-2: Abnormal heat – Ball pressure test
• Part 10-3: Abnormal heat – Mould stress relief distortion test
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
