Classification of environmental conditions - Part 3-4: Classification of groups of environmental parameters and their severities - Stationary use at non-weatherprotected locations

IEC 60721-3-4:2019 classifies groups of environmental parameters and their severities to which products are subjected when installed for stationary use at non-weatherprotected locations. Weatherprotected locations where products can be mounted for stationary use permanently or temporarily are addressed in IEC 60721-3-3. This third edition cancels and replaces the second edition published in 1995 and Amendment 1:1996. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Clause 1: reworded. b) Clause 2: normative references have been updated. c) Clause 3: definitions have been updated. d) Clause 4: reworded and simplified. e) Clause 5: revised and updated. Several classes have been replaced by completely new classes based on the use of new information obtained from referenced technical reports. f) Defined values of chemically active substances are now by reference to ISO 9223. g) Tables 1 through 5: updated.

Classification des conditions d'environnement - Partie 3-4: Classification des groupements des agents d'environnement et de leurs sévérités - Utilisation à poste fixe, non protégé contre les intempéries

L’IEC 60721-3-4:2019 classifie les groupements d’agents d’environnement et leurs sévérités, auxquels sont soumis des produits montés pour une utilisation à poste fixe dans des emplacements non protégés contre les intempéries. Les emplacements protégés contre les intempéries où peuvent être montés les produits pour une utilisation fixe de manière permanente ou temporaire sont traités dans l’IEC 60721-3-3. Cette troisième édition annule et remplace la deuxième édition parue en 1995, ainsi que son amendement 1:1996. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) Article 1: reformulation. b) Article 2: mise à jour des références normatives. c) Article 3: mise à jour des définitions. d) Article 4: reformulation et simplification. e) Article 5: révision et mise à jour. Plusieurs catégories ont été remplacées par des catégories totalement nouvelles fondées sur l’utilisation de nouvelles informations obtenues dans les rapports techniques cités en référence; f) Les valeurs définies des substances chimiquement actives font désormais référence à l’ISO 9223. g) Tableaux 1 à 5: mise à jour.

Klasifikacija okoljskih pogojev - 3-4. del: Klasifikacija skupin okoljskih parametrov in njihove resnosti - Stacionarna uporaba na lokacijah, ki niso zaščitene pred vremenskimi vplivi (IEC 60721-3-4:2019)

Ta del standarda IEC 60721 razvršča skupine okoljskih parametrov in njihove resnosti, katerim so izdelki lahko izpostavljeni pri namestitvi za stacionarno uporabo na lokacijah, ki niso zaščitene pred vremenskimi vplivi. Lokacije, ki so zaščitene pred vremenskimi vplivi, kjer so izdelki nameščeni za trajno ali začasno stacionarno uporabo obravnava standard IEC 60721-3-3.
Okoljski pogoji, navedeni v tem dokumentu, so omejeni na tiste, ki lahko neposredno vplivajo na delovanje izdelkov. Obravnavani so samo okoljski pogoji, ki ustrezajo zgornjemu opisu. Na izdelkih ni podan noben poseben opis vplivov teh pogojev.
Okoljski pogoji, ki so neposredno povezani z nevarnostjo požara ali eksplozije, mikroklimo v izdelku, in pogoji, ki so povezani z učinki ionizirajočega sevanja, so izključeni. Vsakršni drugi nepredvideni dogodki so prav tako izključeni.
Navedeno je omejeno število razredov okoljskih pogojev, ki zajemajo široko področje uporabe.
