Thermal-links - Requirements and application guide
IEC 60694:2015 is applicable to thermal-links intended for incorporation in electrical appliances, electronic equipment and component parts thereof, normally intended for use indoors, in order to protect them against excessive temperatures under abnormal conditions. This standard may be applicable to thermal-links for use under conditions other than indoors, provided that the climatic and other circumstances in the immediate surroundings of such thermal-links are comparable with those in this standard. This standard may be applicable to thermal-links in their simplest forms (e.g. melting strips or wires), provided that molten materials expelled during function cannot adversely interfere with the safe use of the equipment, especially in the case of hand-held or portable equipment, irrespective of its position. Annex H of this standard is applicable to thermal-link packaged assemblies where the thermal-link(s) has already been approved to this standard but packaged in a metallic or non-metallic housing and provided with terminals/wiring leads. This standard is applicable to thermal-links with a rated voltage not exceeding 690 V a.c. or d.c. and a rated current not exceeding 63 A. The objectives of this standard are: to establish uniform requirements for thermal-links, to define methods of test, to provide useful information for the application of thermal-links in equipment. This standard is not applicable to thermal-links used under extreme conditions such as corrosive or explosive atmospheres. This standard is not applicable to thermal-links to be used in circuits on a.c. with a frequency lower than 45 Hz or higher than 62 Hz. This fourth edition cancels and replaces the third edition published in 2002, Amendment 1:2006 and Amendment 2:2010. This fourth edition constitutes a technical revision. This fourth edition includes the following significant technical changes with respect to the previous edition: - requirements for thermal-link packaged assemblies; - renew the requirements and definitions for Th-test; - change starting temperature for interrupt current test; - clarify requirements for marking (packing label); - minimum Proof Tracking Index 175 instead 120. Keywords: thermal protection of equipment, thermal-links

Protecteurs thermiques - Exigences et guide d'application
L'IEC 60691:2015 est applicable aux protecteurs thermiques destinés à être incorporés dans les appareils électriques, le matériel électronique et ses composants, normalement utilisés à l'intérieur d'un local, afin de les protéger contre les températures excessives lors de conditions anormales. La présente Norme peut s'appliquer aux protecteurs thermiques utilisés dans d'autres conditions que celles qui sont réunies à l'intérieur d'un local, pourvu que les conditions climatiques ou autres de l'entourage immédiat de tels protecteurs thermiques soient comparables à celles de la présente Norme. La présente Norme peut s'appliquer aux protecteurs thermiques dans leurs formes les plus simples (par exemple les lames ou les fils de fusion), pourvu que le matériau fondu, expulsé pendant le fonctionnement, ne soit pas préjudiciable à la sécurité du matériel, particulièrement dans le cas du matériel tenu à la main, ou mobile indépendamment de sa position. L'Annexe H de la présente Norme s'applique aux ensembles conditionnés de protecteurs thermiques déjà conformes à la présente Norme mais conditionnés dans un boîtier métallique ou non métallique et munis de bornes/conducteurs à fils. La présente Norme s'applique aux protecteurs thermiques dont la tension assignée n'excède pas 690 V en courant alternatif ou en courant continu, et dont le courant assigné n'excède pas 63 A. Les objectifs de la présente Norme sont les suivants: établir des exigences uniformes pour les protecteurs thermiques, définir des méthodes d'essai, fournir des renseignements utiles pour l'utilisation des protecteurs thermiques dans les matériels. La présente Norme n'est pas applicable aux protecteurs thermiques utilisés dans des conditions extrêmes, telles que des atmosphères corrosives ou explosives. La présente Norme n'est pas applicable aux protecteurs thermiques destinés à être utilisés dans des circuits en courant alternatif avec une fréquence inférieure à 45 Hz ou supérieure à 62 Hz. Cette quatrième édition annule et remplace la troisième édition parue en 2002, l'Amendement 1:2006 et l'Amendement 2:2010. Cette quatrième édition constitue une révision technique. Cette quatrième édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - exigences relatives aux ensembles conditionnés de protecteurs thermiques; - reformulation des exigences et des définitions relatives à l'essai Th; - modification de la température initiale pour l'essai de courant de coupure; - clarification des exigences de marquage (étiquette de conditionnement); - Indice de tenue au cheminement minimum égal à 175 au lieu de 120. Mots clés: protection thermique des matériels, protecteurs thermiques
Termični taljivi vložki - Zahteve in navodilo za uporabo (IEC 60691:2015 + popravek COR1:2016)
Ta mednarodni standard se uporablja za termične taljive vložke, namenjene za vgradnjo v električne naprave in elektronsko opremo ter njihove sestavne dele, ki so običajno predvideni za notranjo uporabo, z namenom zagotavljanja zaščite pred prekomernimi temperaturami v izrednih razmerah.
OPOMBA 1: Oprema ni zasnovana za ustvarjanje toplote.
OPOMBA 2: Učinkovitost zaščite pred prekomernimi temperaturami je seveda odvisna od položaja in načina vgradnje termičnega taljivega vložka ter toka, ki ga prevaja.
Ta standard se lahko uporablja za termične taljive vložke, namenjene za uporabo pri pogojih, ki ne vključujejo notranje uporabe, pod pogojem, da so podnebne in druge razmere v neposredni okolici bližini takih termičnih taljivih vložkov primerljive z razmerami, opisanimi v tem standardu.
Ta standard se lahko uporablja za termične taljive vložke v najosnovnejši obliki (npr. taljivi trakovi ali žice) pod pogojem, da staljeni materiali, ki se izločijo v primeru uporabe vložkov, ne vplivajo škodljivo na varno uporabo opreme, zlasti pri ročni ali prenosni opremi, ne glede na svoj položaj.
Priloga H tega standarda se uporablja za sklope termičnih taljivih vložkov, predhodno odobrenih za uporabo v skladu s tem standardom, ki so vstavljeni v kovinsko ali nekovinsko ohišje in vključujejo priključke/žične vodnike.
Ta standard se uporablja za termične taljive vložke z nazivno napetostjo največ 690 V izmenične ali
enosmerne napetosti in nazivnim tokom največ 63 A.
Namen tega standarda je:
a) vzpostaviti enotne zahteve za termične taljive vložke,
b) določiti preskusne metode,
c) podati uporabne informacije za uporabo termičnih taljivih vložkov v opremi.
Ta standard se ne uporablja za termične taljive vložke, ki se uporabljajo v ekstremnih pogojih, kot so korozivne ali eksplozivne atmosfere.
Ta standard se ne uporablja za termične taljive vložke, predvidene za uporabo v vezjih izmenične napetosti s frekvenco manj kot 45 Hz ali več kot 62 Hz.
