IEC 61163-2:2020

Reliability stress screening - Part 2: Components

IEC 61163-2:2020 provides guidance on RSS techniques and procedures for electrical, electronic, and mechanical components. This document is procedural in nature and is not, and cannot be, exhaustive with respect to component technologies due to the rapid rate of developments in the component industry. This document is:
a) intended for component manufacturers as a guideline;
b) intended for component users as a guideline to negotiate with component manufacturers on RSS requirements;
c) intended to allow the planning of an RSS process in house to meet reliability requirements or to allow the re-qualification of components for specific, upgraded, environments;
d) intended as a guideline to sub-contractors who provide RSS as a service.
This document is not intended to provide test plans for specific components or for delivery of certificates of conformance for batches of components. The use of bi-modal Weibull analysis to select and optimize an RSS process without having to estimate the reliability and life time of all items is described. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) this version of the document is a complete rewrite and restructure from the previous version.

Déverminage sous contraintes - Partie 2: Composants

IEC 61163-2:2020 fournit des recommandations relatives aux techniques et procédures de RSS pour composants électriques, électroniques et mécaniques. Le présent document est de nature procédurale. En raison de l'évolution rapide de l'industrie des composants, elle n'est pas, ni ne peut être, exhaustive au regard de la technologie des composants. Le présent document est prévu pour:
a) les fabricants de composants, en tant que ligne directrice;
b) les utilisateurs de composants, en tant que ligne directrice pour la négociation relative aux exigences de RSS avec les fabricants de composants;
c) permettre la planification d'un processus de RSS interne, destiné à satisfaire aux exigences de fiabilité, ou pour admettre la requalification des composants pour des environnements spécifiques mis à niveau;
d) les sous-traitants qui proposent le RSS comme un service, en tant que ligne directrice.
Le présent document n'a pas pour but de fournir des plans d'essai pour soumettre des composants spécifiques à l'essai ni de délivrer des certificats de conformité pour des lots de composants. L'usage d'une analyse bimodale de Weibull visant à choisir et optimiser un processus de RSS, sans avoir à évaluer la fiabilité ni la durée de vie de toutes les entités, fait l'objet d'une description. Cette deuxième édition annule et remplace la première édition parue en 1998. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) cette version du document a fait l'objet d'une refonte intégrale et a été réorganisée par rapport à la version précédente.

Part 2: Components
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
