IEC 62435-8:2020

Electronic components - Long-term storage of electronic semiconductor devices - Part 8: Passive electronic devices

IEC 62435-8:2020 on long-term storage is applied to passive electronic devices in long-term storage that can be used as part of obsolescence mitigation strategy. Long-term storage refers to a duration that can be more than 12 months for product scheduled for storage. Storage typically begins when components are packed at the originating supplier where the pack date or date code are assigned to the product. It is the responsibility of the distributor and the customer to control and manage the aging inventory upon receipt of the dated product. Alternatively, a supplier-customer agreement can be established to manage the aging inventory. Philosophy, good working practice, and general means to facilitate the successful long-term storage of electronic components are also addressed.

Composants électroniques - Stockage de longue durée des dispositifs électroniques à semiconducteurs - Partie 8 : Dispositifs électroniques passifs

IEC 62435-8:2020 relative au stockage de longue durée s’applique aux dispositifs électroniques passifs à stockage de longue durée qui peuvent être utilisés dans le cadre d’une stratégie de réduction de l’obsolescence. Le stockage de longue durée fait référence à une durée qui peut être supérieure à 12 mois, pour un produit destiné à être stocké. Le stockage commence généralement avec l’emballage des composants dans les locaux du fournisseur d’origine et l’attribution au produit de la date d’emballage ou du code de date. Le distributeur et le client sont tenus de contrôler et gérer le stock des produits vieillissants à réception du produit marqué d’une date. En variante, un accord fournisseur‑client peut être mis en place pour gérer le stock des produits vieillissants. Les concepts, les bonnes pratiques de travail et les moyens généraux de nature à faciliter les bonnes conditions de stockage de longue durée des composants électroniques sont aussi traités.

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 interna-
tional 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, Tech-
nical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publica-
tion(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 Interna-
tional 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 inter-
ested 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 misinter-
pretation 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 be-
tween 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 ex-
penses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publica-
tions.
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.
