1. Scope and Object

1.1

This International Standard 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.

NOTES: (1) The equipment need not be designed to generate heat. (2) The effectiveness of the protection against excessive temperatures logically depends upon the position and method of mounting of the thermal-link, as well as upon the current which it is carrying. (3) Attention is drawn to the fact that the external creepage distances and clearances specified in table 3 may in some cases be smaller than those required by certain appliance or equipment standards. In such cases, additional means should be provided when a thermal-link is mounted in the equipment in order to adjust the creepage distances and clearances to the values required by the relevant equipment standard.

1.2

This standard may be applicable to thermal-links for use under other than indoor conditions, provided that the climatic and other circumstances in the immediate surroundings of such thermal-links are comparable with those in this standard.

1.3

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 c ase of hand-held or portable equipment irrespective of its attitude.

1.4

This standard is applicable to thermal-links with a rated voltage not exceeding 660 V a.c. and a rated current not exceeding 63 A.

1.5

This standard is not applicable to thermal-links used under extreme conditions such as corrosive or explosive atmospheres.

1.6

This standard is applicable to thermal-links primarily intended for use in circuits operating on a.c. with a frequency between 45 Hz and 62 Hz.

1.7

The object of this standard is:

(a) to establish uniform requirements for thermal-links; (b) to define methods of test; (c) to provide useful information for the application of thermal-links in equipment. /

1. Domaine d'application et objet

1.1

La presente Norme internationale est applicable aux protecteurs thermiques destines a etre incorpores dans les appareils electriques, le materiel electronique et ses composants, normalement utilises a l'interieur d'un local, afin de les proteger contre les temperatures excessives lors de fonctionnement anormal.

NOTES. (1) L'appareil peut ne pas etre prevu pour produire de la chaleur. (2) L'efficacite de la protection contre des temperatures excessives depend logiquement de la position et du mode de montage du protecteur thermique ainsi que du courant qui le traverse. (3) L'attention est attiree sur le fait que les lignes de fuite et les distances d'isolement exterieures, specifiees dans le tableau 3, peuvent dans quelques cas etre plus petites que celles exigees par les normes de certains appareils ou equipements. Dans de tels cas, il convient que des moyens supplementaires soient prevus lorsqu'un protecteur thermique est monte dans l'equipement de facon a ajuster les lignes de fuite et les distances d'isolement aux valeurs exigees par la norme de l'equipement concerne.

1.2

Cette norme peut s'appliquer aux protecteurs thermiques utilise s dans d'autres conditions que celles qui sont reunies a l'interieur d'un local, pourvu que les conditions climatiques ou autres de l'entourage immediat de tels protecteurs thermiques soient comparables a celles de la presente norme.

1.3

Cette 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 materiau fondu, expulse pendant le fonctionnement, ne soit pas prejudiciable a la securite du materiel, particulierement dans le cas du materiel tenu a la main, ou mobile independamment de sa position.

1.4

Cette norme est applicable aux protecteurs thermiques dont la tension assignee n'excede pas 660 V en courant alternatif et le courant assigne 63 A.

1.5

Cette norme n'est pas applicable aux protecteurs thermiques utilises dans des conditions extremes, telles que des atmospheres corrosives ou explosives.

1.6

Cette norme est applicable principalement aux protecteurs thermiques destines a etre utilises en courant alternatif avec une frequence comprise entre 45 Hz et 62 Hz.

1.7

La presente norme est destinee: (a) a etablir des prescriptions uniformes pour les protecteurs thermiques; (b) a definir des methodes d'essai; (c) a fournir des renseignements utiles pour l'utilisation des protecteurs thermiques dans les appareils.
