Environmental testing - Part 1: General and guidance

IEC 60068-1:2013 includes a series of methods for environmental testing along with their appropriate severities, and prescribes various atmospheric conditions for measurements and tests designed to assess the ability of specimens to perform under expected conditions of transportation, storage and all aspects of operational use. Although primarily intended for electrotechnical products, this standard is not restricted to them and may be used in other fields where desired. Other methods of environmental testing, specific to the individual types of specimen, may be included in the relevant specifications. The framework of environmental test tailoring process is given in order to assist the production of test specifications with appropriate tests and test severities. This seventh edition cancels and replaces the sixth edition, published in 1988, and constitutes a technical revision. The main changes with respect to the previous edition are listed below: - updated normative reference list; - indication of normative and informative annexes; - new informative Annex C, Environmental test tailoring.

Essais d'environnement - Partie 1: Généralités et lignes directrices

La CEI 60068-1:2013 comporte une série de méthodes d'essais d'environnement et leurs sévérités appropriées et spécifie différentes conditions atmosphériques pour les mesures et les essais, conçues pour garantir l'aptitude de spécimens à être utilisés dans des conditions prévisibles de transport, de stockage et d'utilisation opérationnelle sous toutes ses formes. Bien qu'elle soit destinée en premier lieu à des produits électrotechniques, la présente norme ne s'applique pas uniquement à ceux-ci et peut être utilisée dans d'autres domaines, si on le désire. D'autres méthodes d'essais d'environnement, spécifiques à des types particuliers de spécimens, peuvent être incluses dans la spécification particulière correspondante. Le cadre du processus d'adaptation des essais d'environnement est donné afin d'aider à l'établissement de spécifications d'essai proposant des essais et des sévérités appropriés. Cette septième édition annule et remplace la sixième édition, publiée en 1988, et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - une liste de références normatives mise à jour; - une indication des annexes normatives et informatives; - Une nouvelle Annexe informative - Annexe C: 'Adaptation des essais d'environnement'.

Okoljsko preskušanje - 1. del: Splošno in navodila

Serija standardov IEC 60068 vključuje niz metod za okoljsko preskušanje z ustreznimi stopnjami ter predpisuje različne atmosferske pogoje za meritve in preskuse, ki so bili zasnovani za vrednotenje zmožnosti delovanja preskusnih vzorcev v pričakovanih pogojih med transportom in skladiščenjem ter v vseh vidikih operativne uporabe. Čeprav je primarno namenjen elektrotehničnim izdelkom, ta standard ni omejen nanje in se lahko poljubno uporablja na drugih področjih. Druge metode okoljskega preskušanja, ki so značilne za individualne tipe preskusnih vzorcev, so morda vključene v ustreznih specifikacijah. Okvir za postopek prilagajanja okoljskega preskušanja je podan kot pomoč pri izdelavi preskusnih specifikacij z ustreznimi preskusi in preskusnimi stopnjami. Serija standardov IEC 60068 navaja niz enotnih in ponovljivih okoljskih, klimatskih, dinamičnih in kombiniranih preskusov, ki se izvedejo in izmerijo v standardnih atmosferskih pogojih, za tiste, ki pripravljajo specifikacije, in za tiste, ki se ukvarjajo s preskušanjem izdelkov. Te preskusne metode temeljijo na razpoložljivih mednarodnih inženirskih izkušnjah in presoji ter so prvenstveno zasnovane za zagotavljanje informacij o naslednjih lastnostih preskusnih vzorcev:
a) zmožnost delovanja v okviru določenih mejnih vrednosti temperature, tlaka, vlažnosti, mehanskih vplivov ali drugih okoljskih pogojev in kombinacij teh pogojev;
b) zmožnost odpornosti na pogoje transporta, shranjevanja in namestitve.
OPOMBA 1 Serija standardov IEC 60721 navaja sistem za razvrščanje okoljskih pogojev in vsebuje ustrezne definicije. Preskusi v tem standardu omogočajo primerjavo zmožnosti delovanja vzorčnih izdelkov. Za ocenjevanje kakovosti ali življenjske dobe dane proizvodne serije se morajo preskusne metode uporabljati v skladu s primernim načrtom vzorčenja in se lahko po potrebi nadgradijo z ustreznimi dodatnimi preskusi. OPOMBA 2 Standard ISO določa »kakovost« kot stopnjo, do katere nabor svojstvenih lastnosti izpolnjuje zahteve. OPOMBA 3 »Življenjska doba«: v danih pogojih je to časovno obdobje, ki se začne ob točno določenem času in konča, ko postane pogostost odpovedi izdelka nesprejemljiva ali ko izdelka zaradi okvare ni več mogoče popraviti. Nekateri preskusni postopki imajo več stopenj, da se zagotovijo preskusi, ki so primerni za različne stopnje intenzivnosti okoljskih pogojev. Te različne stopnje se pridobijo s spreminjanjem časa, temperature, zračnega tlaka ali katerih drugih odločilnih dejavnikov, ločeno ali v kombinaciji. Ker morajo preskusi in stopnje temeljiti na resničnih okoljskih pogojih, na katere lahko določeni preskusni vzorec naleti, so navedeni okvir in potrebne faze za postopek prilagajanja okoljskega preskušanja. Postopek za prilagajanje preskušanja se lahko uporabi za izdelavo zahtevanih ustreznih preskusnih specifikacij za določeni preskusni vzorec.

Part 1: General and guidance
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 60068-1 has been prepared by IEC technical committee 104:
Environmental conditions, classification and methods of test.
This seventh edition cancels and replaces the sixth edition, published in 1988, and constitutes
a technical revision.
The main changes with respect to the previous edition are listed below:
– updated normative reference list;
– indication of normative and informative annexes;
– new informative Annex C, Environmental test tailoring.
